01 / Summary

⚡ Quick answers

For readers who want the conclusions first. Every claim carries a source reference [in brackets], indexed in the sources table at the end.

  1. 01

    🏁 Step zero: check your PMS

    Rent Manager ships a full phone platform (rmVoIP); evaluate it before buying anything here. AppFolio, Buildium, and Rentvine all text natively but ship no staff phone, and AppFolio's Realm-X now answers leasing calls with voice [S23, S43, S44]. Full table in the PM-native stack section.

  2. 02

    💰 Cheapest complete phone platform

    Zoom Phone US & CA Unlimited at $16/user/month with unlimited calling and texting [S5, verified]. Dialpad is $1 cheaper but caps texting.

  3. 03

    📞 Best voice AI receptionist

    Zoom Virtual Agent Receptionist: $24.99 to $29.99/month per 100 minutes, roughly $0.25 to $0.30 a minute, self-serve, and it works with any phone platform [S7, verified]. Best PM-native: Super, from $415/month with 1,000 minutes plus unlimited email and SMS handling, roughly $0.40 a minute [S31, verified].

  4. 04

    📊 Voice AI by the minute

    Published rates run $0.25 to $0.30 (Zoom), $0.29 to $0.49 (Aircall, whose pages have shown two competing rate sets since a July 30, 2026 price cut; we cite the higher, which its billing docs charge; custom bundles from $0.19 at 10,000+ minutes), $0.40 (Super, LeadSimple), and $0.50 overage (RingCentral). Quo prices per call ($0.45 to $1.00), and Dialpad publishes no rate. Full comparison table in the AI section.

  5. 05

    🔌 Best for automation and integrations

    Aircall, scoring 19/20 on our Connectability framework [S2, S3].

  6. 06

    🛠️ Best API for a custom build

    Aircall, the only platform that delivers transcripts, sentiment, and summaries as webhook events, with API access on every plan [S3, verified]. Broadest overall surface: RingCentral, including the only documented API-level call supervision [S37]. Dialpad's API requires Pro, a $75/month real floor [S36], and Zoom's API docs indicate Business tier or above [S9]. Full build comparison in the Connectability section.

  7. 07

    😊 Cheapest sentiment analysis

    Aircall's $9/license AI Assist [S16, verified]. It's expensive everywhere else: RingCentral wants a $60/user/month add-on [S11], and Dialpad only sells sentiment inside its $80+/user contact-center products, not its phone plans [S10, verified].

  8. 08

    🧮 Full AI stack for a 5-person office

    Roughly $170/month on Zoom, $317/month on Aircall, $264 or $564/month on RingCentral depending on whether you add sentiment [calculated].

  9. 09

    🧰 Thinking of building it yourself on Twilio?

    The unit prices are the cheapest in this guide (numbers from $1.15/month, calls from $0.0085/minute [S4, verified]) and they buy parts, not a phone: softphones, queues, voicemail, E911, and A2P compliance all become your engineering. Build features there, not your phone platform; the full argument is in the build-it-yourself section below.

02 / Method

🔍 How we verified this (and what we couldn’t)

Every price in this guide was read from the vendor’s own live pricing page, checkout flow, or billing documentation, with a full-page screenshot archived as evidence for each one. Third-party pricing articles drift out of date; primary sources don’t, and buyers who rely on secondhand numbers walk into sales calls anchored wrong. That discipline is how this guide caught a recent Zoom price increase most published comparisons still miss: Unlimited is now $16, not the widely cited $15.

Our verification hierarchy, in order of preference: 1. Vendor billing documentation (help center articles that explain actual invoices must match what customers are charged). 2. Vendor pricing and product pages for plan structure, feature lists, minimums, and displayed rates. 3. Independent corroboration where vendors hide numbers, requiring agreement across at least three independent 2026 analyses, noting conflicts rather than picking one silently.

Confidence labels: Verified means it comes from the vendor’s own documentation. Corroborated means three or more independent 2026 sources agree. Estimated means we calculated it and show the math.

And it stays verified. An automated watch re-checks roughly 100 claims in this guide against the vendors’ live pages every week, and material changes land in the dated update log at the end. That system caught Aircall’s July 30 AI price cut the day it happened, and, eleven days later, that same cut appearing and disappearing between page sessions.

What we could not fully verify: Zoom’s Virtual Agent Receptionist volume tiers above the 100-minute entry bundle (not published anywhere public). Dialpad’s seat minimums (Standard 1, Pro 3; its checkout hides license counts behind account creation, so these remain corroborated only). Dialpad’s AI Agent pricing (quote-only by design) [S13]. RingCentral’s real-world invoice inflation, which remains a corroborated estimate [S17]. Everything else, including Zoom’s checkout-only Global Select price, is verified against vendor pages or vendor checkout flows.

03 / Requirements

What actually matters for a PMC

Seven things separate a phone platform that works for property management from one that fights you.

Unlimited texting

Tenants text. Owners text. Vendors text. Any plan that caps SMS is a trap for a PMC. Two of the plans below have caps that will bite you within the first week.

Call recording you can actually retrieve

When a tenant claims you never told them about the lease violation, the recording is your defense. Check how long recordings are stored and how hard they are to pull. Aircall's entry plan, for example, keeps recordings a year but only surfaces the last six months in the dashboard [S2].

Ring groups and routing by department

Leasing calls go to leasing. Maintenance calls go to maintenance. After-hours emergencies escalate. If setting this up requires an IT consultant, the platform is wrong for your size.

After-hours coverage

This is where AI receptionists have gotten genuinely good in the last year. A system that answers at 11pm, determines whether the call is "my heat is out" or "when is rent due," and routes accordingly is now a $30 to $50 per month line item, not an enterprise project [S7].

A2P compliance handled for you

If you send automated texts (rent reminders, showing confirmations), US carriers require 10DLC registration. The good platforms handle this registration inside the product. If a vendor can't explain how they handle it, walk.

Channel parity

Tenants who call also text, and they expect the same treatment on both. Whatever a product does for calls, demand it for SMS: if the AI answers calls, it should answer texts (Aircall's messaging agents and RentEngine AI do; many voice agents don't), and if calls log into your systems, texts must too. A stack with voice-only AI leaves half your inbound conversations unhandled.

You can change it yourself

Setup happens once; changes happen forever. Routing tweaks, a new after-hours flow, deploying or reconfiguring an AI agent: on the right platform these are a settings page your office manager owns, and on the wrong one they're IT tickets. A platform you can't change without help costs more than its price, and this requirement decides our 500+ door recommendation below.

04 / The map

🗺️ First, sort the market: platforms, specialists, or build it yourself

The single most confusing thing about this market is that vendors blur different kinds of products. Sort everything into one of three buckets before comparing anything, because the buckets don't compete with each other. (One term note: the industry says phone system; this guide says phone platform for bucket one, so the platform your team staffs is never confused with the specialists you add on top.)

☎️ Bucket one: phone platforms. You need exactly one.

The test: your team logs into it to make and take calls. This is where your seats, numbers, and softphones live, and everything in this bucket competes with everything else in it.

Phone platformWhat kind

DialpadStandalone platform; the small-shop pick (reviewed below)

LeadSimple Phone + InboxCRM-native phone platform
Your PMS's built-in phonePMS-native phone platform. Rent Manager's rmVoIP is the only full one we've verified; if your PMS ships one, evaluate it before anything else in this guide

Google Voice doesn’t get a row on purpose. It technically passes the bucket-one test (your team logs into it to call), but it’s a consumer product: no real IVR, no A2P texting compliance path at business scale, no support. If it’s carrying your business line today, any row in this table is an upgrade.

🧩 Bucket two: specialists. You add zero or more on top.

The test: it takes one specific job on your phone tree, answering or handling those calls before, after, or instead of your team, and nobody on your staff logs into it as their phone. Think of how you staff: a leasing specialist, a maintenance coordinator, a front-desk receptionist each own one kind of call. Bucket two is the software version of those roles. Specialists attach at different scopes: some take a single branch of your phone tree (a leasing line, an after-hours maintenance line), and some want the trunk (your main number, which is Super’s model). In practice a PMC assembles a phone tree out of products, and the platform is whatever holds the trunk and the humans. Whichever specialists you pick, your team still needs seats from bucket one. Within this bucket, the critical distinction is portability.

SpecialistWorks withExamples
Generic AI receptionistsAny phone platformZoom Virtual Agent Receptionist ($24.99-29.99/mo per 100 min) [S7], RingCentral AIR standalone ($49/mo) [S18]
PM-native AI receptionistsAny phone platformSuper (from $415/mo) [S31], EliseAI (quote-only, platform-scale) [S49], Haven AI (quote-only) [S32]
Platform-bound AI agentsOnly their own platformAircall AI Voice + Messaging Agents [S1, S34, S35], Quo's Sona [S28], LeadSimple's AI voice agent [S24], Dialpad's AI Agent [S13]
Leasing specialistsAny phone platformTenant Turner ($1.17-2.43/unit) and ShowMojo ($1.30-2.70/unit) [S25]; RentEngine (results-based pricing, voice AI answering) [S40]; AppFolio Realm-X Leasing Performer (native to AppFolio, multilingual voice) [S44]
Maintenance specialistsAny phone platformLatchel, Property Meld MAX On-Call (add-on), Vendoroo, EZ Repair Hotline [S26, S33]

Three rules fall out of this. One: pick exactly one phone platform; adding a second is how PMCs end up paying for empty seats. Two: platform-bound agents are a switching cost in disguise; if you build your after-hours flow on Aircall’s agent or Quo’s Sona, it doesn’t come with you when you change platforms, while Super, Haven, Zoom VA, and RingCentral AIR all do. Three: every call a specialist resolves is a call your phone platform never rings for, so choose your specialists first and size your seats second.

🧰 Bucket three: build it yourself. You own the engineering.

The test: nothing exists until you build it, and nothing stays working unless you maintain it. This is programmable telephony. Twilio sells the raw materials every product in buckets one and two is made of (numbers, minutes, messages, APIs) at unit prices that embarrass everyone [S4], and in 2026 an AI coding assistant makes the demo look easy. Two paths run through this bucket:

PathWhat it is
Raw TwilioNumbers, minutes, and APIs; every phone-platform feature your team relies on becomes your engineering (reviewed below)
Twilio + Super as the agent harnessThe middle path builders are taking: cheap dial tone from Twilio, with Super supplying the PM-trained agent layer. Per our July 2026 conversations, Super supports this builder configuration directly: prompts are self-serve editable, the agent behaviors come PM-trained out of the box, and its team works with builders on implementation [S39]

The rule for this bucket, argued in full in its review below: build features on Twilio; don’t build your phone platform on it. For a PMC, bucket three is the right door only when phone capability is a feature of your software, not the office phone.

05 / The platforms

☎️ The four platforms

Generic phone-platform roundups will push you toward Nextiva, 8x8, or GoTo Connect. In the PM operator communities we work in and researched for this guide, those names essentially never come up. These four are what PMCs actually discuss and deploy, plus a wildcard, two affiliate-marketed imports, a word-of-mouth pick, and the build-it-yourself door (Twilio) reviewed after them.

🏷️ The value pick

Zoom Phone

Price: $16/user/month for US & CA Unlimited with unlimited domestic calling and unlimited SMS/MMS [S5, verified]. A $10.50 metered plan exists but caps texting at roughly 20 messages per month, which rules it out for any PMC that texts tenants [S5, S12]. Global Select (sold at checkout as Pro Global Select Unlimited) is $22/user/month billed annually ($264/year) or $25 monthly; Zoom only shows this price inside its checkout flow, and third-party sources still widely cite the outdated $20 [S12, verified]. Workplace bundles: Pro Plus at $20.50 and Business Plus at $24.50 per user/month annual [S5, verified]. Two billing gotchas: Zoom bills annual plans as a single upfront charge, and the "monthly" rates shown on its pricing page are for comparison only; true month-to-month billing runs higher (Business Plus is $29 billed monthly). Zoom also raised these prices recently (Unlimited was $15 into mid-2026), so most third-party comparisons you'll find are a dollar or two stale.

What’s verified good: Zoom's own pricing and features pages confirm that unlimited auto-attendants/IVR, call queues with automatic call distribution and overflow rules, barge/monitor/whisper/takeover, holiday routing, call park, and call recording are included on every Phone plan, including the cheapest [S5, S22, verified]. Competitors reserve most of that list for plans costing twice as much. AI Companion post-call summaries, voicemail prioritization, and voicemail task extraction are included at no extra charge [S5, verified]. In July 2026, Zoom launched its Virtual Agent Receptionist as a standalone product from $29.99/month per 100 minutes ($24.99 with annual billing) that answers around the clock, books appointments, routes calls, and works even without Zoom Phone [S7, verified]. Zoom Phone plans include a free Virtual Agent Receptionist trial with 100 minutes [S5]. Add-ons are cheap and published too: extra numbers are $5/month (Aircall charges $6) and the Power Pack, with enhanced call queue analytics, is $25/month [S5, verified].

What’s not: CRM and software integrations are surface-level. monday.com's native Zoom integration covers meetings, not phone [S8, verified]. Connecting Zoom Phone to your operations stack means the API [S9] and custom work. Zoom also prices its bundles to pull you into the full Workplace suite, which is a good deal if you'll use it and shelf-ware if you won't.

Right for: PMCs of any size that want maximum calling features at minimum cost and don't need deep software integrations out of the box.

🎙️ The small-shop pick

Dialpad

Price: $15/user/month (Standard, annual), $25 Pro [S13, verified]. Monthly billing: $27 and $35 [S13, verified]. Standard has no seat minimum; Pro requires 3 licenses and Enterprise 100 [S13, corroborated].

What’s verified good: Real-time call and voicemail transcription and AI call summaries (Recaps) are included at the $15 base price with no add-on [S10, S13, verified]. No other platform here matches that. For a small PMC, every maintenance call automatically transcribed and searchable is a quiet superpower. And it's the only platform a true solo operator can buy without paying for empty seats.

What’s not: Sentiment analysis is not in the phone product, despite what nearly every third-party comparison claims (including an earlier draft of this guide): Dialpad's own help center states sentiment analysis is available on Dialpad Sell and Dialpad Support, the contact-center products, on all their plans, which places it behind an $80+/user seat rather than the $15 one [S10, verified]. SMS overages kick in after 250 messages per user per month (pooled across the office) at $0.008 per delivery attempt, and the allowance requires 10DLC Campaign Registry registration [S19, verified]. CRM integrations (Salesforce, HubSpot, Zendesk) require the $25 Pro tier [S13]. The $15 Standard plan has no API access at all; Dialpad's help center states API keys can only be created on Pro and Enterprise plans [S36, verified], and 24/7 customer support is likewise listed as a Pro addition [S13, verified]. Great AI, no plumbing, and thin help when something breaks: the real floor for a business that needs an API or round-the-clock support is Pro at $25 with its 3-seat minimum, $75/month. Deeper AI like CSAT scoring lives in Dialpad Support, a separate product at $80/$115/$150 per user/month [S13, verified]. And its AI voice agents are quote-only with conversation-based pricing that Dialpad does not publish [S13], so after-hours AI answering means a sales call just to learn the cost.

Right for: Solo operators and small PMCs under roughly 250 doors that want call intelligence cheap and don't need an AI receptionist yet.

🔌 The operations pick

Aircall

Price: $30/license/month Essentials, $50 Professional, annual billing, with a 3-license minimum confirmed on Aircall's own pricing page [S2, verified]. Monthly billing: $40 and $70 [S2, verified]. Real floor: $90/month.

What’s verified good: Aircall publishes its AI billing mechanics in more detail than any vendor here, which we respect [S1]. The platform integrates natively with 250+ business tools [S2], the API is clean and well documented [S3], and every major automation platform supports it deeply. Call tagging, dispositions, and analytics are genuinely useful for tracking whether leasing calls become showings. Its AI Voice Agent is self-serve with no contract: enable it in the dashboard and pay for what you use [S1, verified]. The published rates as of August 10, 2026: pay-as-you-go $0.49/minute up to 2,500 minutes and $0.39 past that, bundles at $175 for 500 minutes and $725 for 2,500 ($0.35 and $0.29/minute), custom bundles from $0.19/minute at 10,000+ minutes, and 50 free minutes per account per month [S34, verified August 10]. Those rates moved twice while we watched: Aircall cut them roughly 25 percent on July 30, 2026 ($130 and $550 bundles, pay-as-you-go from $0.37), a change our automated price watch caught the day it happened, then largely walked it back: by August 10 our repeated fresh-session captures mostly show the pre-cut rates again, with the cut rates ($130/$550 bundles) still appearing in a minority of sessions the same day, which looks like price testing or a staggered rollback; we cite the higher set because Aircall's billing documentation charged it the entire time [S1, S34] and a sales quote we reviewed dated August 7 was priced at it too [S47]. The takeaway for a buyer: this meter's price is in motion, so check the live pricing page the week you sign, get the all-in rate in writing, and treat published tiers as a ceiling in any sales conversation. Aircall is also the only vendor in this guide publishing per-conversation pricing for AI messaging agents on SMS and WhatsApp: $0.35/conversation pay-as-you-go dropping to $0.29 past 1,000 conversations/month, with bundles at $250 for 1,000 and $1,500 for 10,000 [S35, verified].

What’s not: It's the most expensive option, and the pricing stacks add-ons. AI Assist (transcription, summaries, key topics, action items, and sentiment analysis) is a $9/license add-on that must be applied to every license on the account, included free only on the $50 Professional tier [S16, verified]. AI Assist Pro with live transcription and real-time coaching is $49/license [S16, verified]. The power dialer and Salesforce CTI require Professional [S2, verified]. Each plan includes one phone number; extras are $6/month [S2]. And the seat price isn't the whole seat price: a real August 2026 quote adds $4.98/user/month in compliance/administrative and E911 recovery fees that appear on no public page [S47]; details in the billing-predictability ranking.

Right for: Growing PMCs (roughly 250 to 1,500 doors) where the phone team is a real department, call data needs to flow into your operations system, and the productivity gain justifies the premium.

🏢 The established pick

RingCentral

Price: Core $20, Advanced $25, Ultra $35 per user/month annual; $30/$35/$45 monthly [S11, verified]. Add regulatory fees of roughly $3 to $5 per seat per month; multiple independent 2026 analyses report real invoices running 15 to 30 percent above sticker [S17, corroborated].

What’s verified good: The most complete feature set of the group. Advanced at $25 is the sweet spot: automatic call recording, call monitoring, and CRM integrations from a catalog RingCentral itself puts at over 500 apps [S11, S21]. (Core includes on-demand recording only [S11, verified].) Video meetings and team chat are bundled, so it can replace two or three other subscriptions. AI transcription is included even on Core [S11].

What’s not: The Core plan caps texting at 25 SMS per user per month, Advanced at 100, and even Ultra caps at 200 [S11, verified]. For a PMC, Core's cap is gone by Tuesday, which makes Advanced your real starting price. Sentiment analysis requires the Conversational Intelligence add-on (formerly RingSense), starting at $60/user/month and built for enterprise sales coaching [S11, verified]. The AI Receptionist (AIR) is $39/month as a RingEX add-on or $49/month standalone, with 100 minutes included and then $0.50/minute billed in 30-second increments [S18, verified], the steepest AI metering in this comparison. Like Zoom's receptionist, the standalone version works with any phone platform. And our take from hands-on work: it's the heaviest platform here to administer. The depth is real, but day-to-day changes an office manager makes in minutes on a modern platform tend to become admin-console projects here; we weigh this against it in the 500+ recommendation below.

Right for: Mid-size PMCs (500+ doors) that want one vendor for phone, video, and chat, and have someone on staff who will actually read the invoice.

06 / The rest of the field

🃏 The wildcard, two listicle regulars, and one the listicles never find

Quo (formerly OpenPhone) stays out of our category rankings to keep the four-way comparisons clean, but at the solo end it’s the platform your peers will actually mention. Starter $15, Business $23, Scale $35 per user/month annual [S28, verified]. Every plan now includes Sona, Quo’s AI agent that answers calls 24/7, with 10 AI-handled calls a month free; past that, credit packs run $25/month for 40 calls up to $199 for 600, with per-call overages from $1.00 down to $0.45 [S28, verified]. Note the unit: Quo prices AI answering per call while everyone else prices per minute, which makes it cheap for short “is the unit still available” calls and expensive for a 12-minute maintenance walkthrough. Quo also lists ChatGPT/Claude MCP support on its plans, making it the only platform in this guide besides Zoom speaking MCP. The tradeoff: this is a phone for a small customer-facing team, not a phone department. Right for solo operators and sub-100-door shops: $15/month all-in if 10 AI calls cover your after-hours volume.

KrispCall is $12/user/month billed annually ($15 monthly) for Essential, capped at 5 users, and $32 ($40 monthly) for Standard [S29, verified]. Here’s what the listicles don’t lead with: every KrispCall plan is metered. “Calling & SMS charges applicable” appears on all three tiers, meaning pay-per-minute calling and pay-per-segment texting on top of the seat price, plus itemized 10DLC pass-through fees [S29, verified]. Calling and SMS are limited until you complete KYC document verification. It’s built for cheap international virtual numbers, and it’s fine at that job. But this guide’s standing rule applies: for a PMC, skip metered plans entirely.

CallHippo is the more serious contender: Starter at $19/user/month billed yearly ($25 monthly) includes unlimited US and Canada calling; Professional at $30 ($40) adds call recording and multilingual IVR; Ultimate at $42 ($55) adds multilevel IVR and holiday routing [S30, verified]. The PMC problems are in the fine print: texting caps at 100, 500, and 1,000 SMS per month by tier, an AI Voice Agent at $45/user/month (the most expensive AI answering path in this guide), and two add-ons that tell you something the marketing doesn’t: a $100-per-number “Remediation Service” to remove spam flags and a $3/number/month “Spam Watch” [S30, verified]. When a vendor sells spam-flag cleanup for its own numbers, weigh number reputation before routing your leasing line through it.

Bottom line: if budget is what’s driving you here, Dialpad at $15 and Zoom at $16 beat both on PMC fit with unlimited calling, real included AI, and no metering surprises. Both KrispCall and CallHippo run aggressive affiliate programs, which is why review sites rank them highly. Neither appears in the PM operator communities we researched.

📇 The one the listicles never find: SimpleVoIP

SimpleVoIP (simplevoip.com) is the mirror image of KrispCall and CallHippo: it appears in no “best VoIP” roundups, runs no affiliate program, and publishes no prices, but it’s running in real AppFolio shops. It got into this guide the way no listicle entry does: an operator told us about it. It’s a managed, white-glove VoIP provider for multi-location SMBs with a dedicated property-management product, CRM Connect, listed in the AppFolio Stack Marketplace [S41]. Pricing is quote-only; the plans page lists tiers with features but no numbers [S41]. One real-world data point: an AppFolio-based PMC we interviewed in July 2026 pays about $170/month for a four-number setup (one main line plus rollover lines), the same or slightly less than their previous provider [S42, interview-sourced].

What it does that nothing else in bucket one does for AppFolio shops: CRM Connect embeds into AppFolio through a Chrome extension and mobile app. Inbound calls auto-load the matching tenant, owner, or vendor record; dialing from inside AppFolio routes through SimpleVoIP and gets logged; and calls, AI transcriptions and summaries, and recordings attach themselves to the right record with no manual entry [S41]. The operator we interviewed confirmed it works as advertised: transcripts land on the tenant, owner, and vendor cards, and the screen pop is real, real enough that they toggled it off on desktop because the auto-opening tab interrupts other work (worth asking about in the demo) [S42]. This is the caller-context workflow Rent Manager shops get natively from rmVoIP, and it’s the closest thing to it that exists for AppFolio. SimpleVoIP also launched its own voice AI in 2026, Simple Agent: inbound and outbound handling, trainable, with configurable guardrails, and unpriced [S41]. The operator we interviewed doesn’t use it; they run RentEngine for AI leasing calls alongside SimpleVoIP, which is exactly the platform-plus-specialists architecture this guide recommends.

The caveats: no public pricing means this guide’s sales-call rule applies, the site lists Platform and Customer APIs but publishes no documentation (so we can’t give it a Connectability Score), and with no self-serve signup you’re buying a managed-service relationship: white-glove support on one side, nothing you can spin up and test on a Tuesday on the other. Right for: AppFolio shops that want every call documented against the right record out of the box. If that’s your pain, this is the only phone platform in this guide purpose-built to fix it.

🧰 Bucket three reviewed: the build-it-yourself door (Twilio)

Bucket three deserves a full review, because the pitch is real: skip phone platforms entirely and build on programmable telephony. Twilio sells the raw materials every phone product is made of: numbers, minutes, messages, and APIs. The unit prices embarrass everything above: US local numbers from $1.15/month, inbound calls at $0.0085/minute, outbound at $0.0140, SMS at $0.0083 a message, and browser-based call legs at $0.0040/minute [S4, verified]. A five-seat office’s raw telephony (two numbers, roughly 3,000 minutes, 1,500 texts) runs about $46 a month in usage [estimated; rerun with your volumes]. Zoom charges $80 for the same office. That gap is the entire pitch, and in 2026 an AI coding assistant will get a working Twilio call flow running in an afternoon, which makes the pitch feel even better.

Here is what the afternoon demo doesn’t include, because on Twilio nothing exists until you build it: softphones your team logs into, ring groups, queues, voicemail, holiday routing, recording storage and a retention policy, an admin panel, presence, analytics, E911 registration, A2P 10DLC brand and campaign registration, spam-reputation monitoring, and someone on call when any of it breaks. That is not configuration; that is a product. Every platform in bucket one is thousands of engineering hours wrapped around these exact parts (several products in this guide are assembled from this same class of infrastructure), and Twilio sells its own packaged contact-center product precisely because parts are not a phone platform. The honest math: the ~$34/month saved versus Zoom is erased by the first hour of monthly maintenance, before the build itself costs a dollar [estimated].

When Twilio IS the right answer for a PMC: when phone capability is a feature of your software rather than the office phone. A rent-reminder SMS service wired to your PMS, a custom voice AI experiment, an after-hours line with logic no vendor sells: those are point builds where you want an API, not a seat. Which is also the advanced-build trap in reverse: for the integration-heavy stacks this guide recommends, a platform API such as Aircall’s, with its event stream and AI data on top of an already-working phone, gets you the custom behavior without owning dial tone. Build features on Twilio; don’t build your phone platform on it. One pattern worth knowing about, described to us by Super in July 2026 [S39]: builders increasingly pair Twilio’s telephony with a hosted agent platform as the harness, keeping the dial tone cheap while renting the agent infrastructure. Super is the concrete PM-native option for that harness: it gives builders a PM-trained agent layer without making them buy a phone platform around it, with agent prompts that are self-serve editable after onboarding and, per our conversations, a team that works directly with builders on implementation [S39]. That’s a middle path between raw parts and a finished product, and it’s where bucket three is heading.

07 / The PM-native stack

🏠 The part generic comparisons miss: PM software is eating the phone platform

Four categories of PM-specific software are already answering calls that would otherwise hit your phone platform. Size your phone platform for what’s left.

Your PMS might already be a phone platform. Rent Manager’s rmVoIP is a full hosted phone platform built into the PMS: when the phone rings, a screen pop shows the caller’s payment history and open service issues, and every call is recorded and attached to the contact’s record automatically [S23]. If you’re on Rent Manager, evaluate rmVoIP before anything in this guide. AppFolio and Buildium have no equivalent native voice, but be precise about which channel is missing: both text natively. AppFolio handles resident texting through Realm-X Messages, a central inbox for text and email, and Buildium lets you send and receive texts without leaving your Buildium account, free as a feature with resident opt-in tracked [S43]. What neither ships is a phone your team can call from. On the AI side, though, AppFolio crossed into voice in June 2026, and we initially missed it: Realm-X Leasing Performer is now generally available with multilingual voice, answering leasing calls natively 24/7 and scheduling showings in an average of 2.5 minutes on the phone by AppFolio’s numbers [S44]. In this guide’s terms that’s a PMS-native leasing specialist: it takes the leasing branch of your phone tree, but your team still can’t make or take a call inside AppFolio, and the rest of AppFolio’s AI (Smart Maintenance, Resident Messenger) remains chat and email-first [S27, S44]. Rentvine is the same story without the voice chapter: chat, email, and text are native, there’s no calling, and the documented phone path for Rentvine shops is LeadSimple’s Phone + Inbox via its direct Rentvine integration [S45]. That has a channel-parity consequence: an AppFolio or Buildium shop buying from this guide is buying the voice half of conversations its PMS already half-handles by text, which is exactly why calls need to log back into the PMS (SimpleVoIP’s CRM Connect, reviewed above, bolts that screen-pop-and-auto-log workflow onto AppFolio from the Stack Marketplace). Short of that, AppFolio and Buildium shops are the ones shopping this guide’s four platforms.

Here’s the whole picture in one place. Step zero of any phone decision is this table: find your PMS’s row, and buy only the channels it doesn’t already cover.

Buildium✅ Send and receive in-app, free, opt-in tracked [S43]Buy voice from bucket one
Rentvine✅ Native, with templates and mass texting [S45]LeadSimple Phone + Inbox has a direct Rentvine integration [S45]

Yardi and Entrata sit outside this table: their call products, RentCafe Connect and Entrata’s AI voice, are contact-center services and agents, bucket-two specialists sold into enterprise multifamily, not staff phone platforms.

Your CRM might already be a phone platform. LeadSimple, the CRM most process-driven PMCs run their sales and operations on, now bundles Phone + Inbox: VoIP calling, texting, call recording, IVR, ring groups, warm transfers, and its own AI voice agent, in one timeline tied to your workflows. Its pricing has moved three times in the three weeks we’ve been watching: a $29 Core tier with 300 minutes existed on July 24, was gone by July 29 (one $59 plan), and by August 10 a two-tier structure is back in a new shape. Core at $29/user/month ($35 month-to-month) is the shared inbox with an IVR phone menu; Pro at $59/user/month ($65 month-to-month) adds ring groups, warm transfers, hours-based routing, call recording, and the AI voice agent, with 600 call minutes, 1,200 SMS segments, and 45 AI voice minutes per user [S24, verified August 10, 2026]. The overage rates published in July (5 cents per call minute, 2.5 cents per SMS, $0.40 per AI voice minute) are no longer on the pricing page; assume they still apply and confirm before you buy. It’s sold as its own plan, pairable with LeadSimple’s CRM or Operations products (a Core + CRM bundle runs $128/month for the first seat), with a per-door contract offered that bundles everything with unlimited calling and texting. Two honest caveats: the seat plans are metered minutes, not unlimited calling, and the seat to compare against a phone platform is the $59 Pro, because that’s where the routing and the voice agent live. The case for it is no longer price; it’s that a phone that logs itself against the right process beats a better phone that doesn’t.

Leasing calls mostly shouldn’t reach your phone platform at all. Showing-scheduling platforms answer them first, and they price per unit, not per seat. Tenant Turner runs $1.17/unit/month on annual Pro plans, or $2.43/unit for Ultra, which adds a live leasing call center; ShowMojo’s equivalent plans are $1.30 and $2.70/unit with its Live Answer agents [S25, verified]. AppFolio shops have an option in the PMS itself: Realm-X Leasing Performer answers leasing calls with multilingual voice, natively, 24/7 (pricing not published; Performers are an add-on with minimum spend) [S44], and it belongs in this comparison before you buy a separate leasing line. RentEngine (rentengine.io) is the fuller-platform entry in this lane: marketing and syndication to 30+ listing sites, a leasing CRM, two-way texting and calling, rental applications, PMS sync, and an open API, priced on results rather than a monthly software fee (one-time onboarding fee; rates are quote-only) [S40, verified as displayed]. Its RentEngine AI is the one leasing specialist here that answers calls with voice, not just chat: it picks up inbound leasing calls 24/7, answers questions, qualifies, and schedules tours, alongside text [S40]; its faster-leasing claims are vendor-reported. Disclosure: LaunchEngine builds a monday.com integration for RentEngine; the description here comes from their published pages like every other entry. At 200 doors, a fully live-answered leasing line costs about $500/month, and every leasing call it absorbs is one your team never handles. If your leasing line still rings to a human in your office, fixing that will do more for you than any phone platform swap in this guide.

After-hours maintenance is its own market, and it’s the real competitor to AI receptionists. Latchel pairs AI-guided troubleshooting with human experts who pick up in about 15 seconds (pricing not published); Property Meld’s MAX On-Call does 24/7 conversational AI triage, sold as an add-on on top of the platform’s $1.60 to $2.00/unit/month [S26, verified]; EZ Repair Hotline is the legacy human call-center option. Vendoroo is the name making the most noise in this lane right now, with heavy PM-podcast and NARPM presence: an AI maintenance coordinator paired with a human expert, running the full lifecycle from triage through vendor dispatch, invoicing, and payment, inside your existing PMS, on month-to-month terms [S33]. Its current plans publish no prices, though a still-live older calculator page on its own site lists the basic coordination module at $5/door/month; treat that as indicative and confirm on the call. The honest comparison for a PMC isn’t “Zoom’s receptionist vs RingCentral’s receptionist.” It’s a generic AI receptionist at $25-50/month that routes and takes messages, vs a maintenance-native service that actually troubleshoots the leak, dispatches the plumber, and logs the work order. Generic wins on price and breadth; maintenance-native wins on depth.

The PM-native AI receptionist has arrived, and it splits the difference. Super (hiresuper.com) is the most credible attempt yet at the middle: a voice AI built specifically for property management, with a NARPM presence and FirstService Residential on its client list [S31]. Unlike most of this category, it publishes pricing: Outreach agents from $150/month with 250 minutes, the 24/7 Receptionist from $415/month with 1,000 minutes plus unlimited email and SMS handling, or both from $515/month [S31, verified]. That’s roughly $0.40 per minute, pricier than Zoom’s generic receptionist, and the premium buys resolution: Super claims to resolve about a third of inquiries end to end with no human (vendor-reported), with two-way PMS integrations that create the work order, enter the guest card, and schedule the showing. Two updates from our July 2026 conversation with Super and our own calls to its public demo agent [S39]: agent prompts are editable self-serve on their platform after onboarding, and the demo agent handled a maintenance scenario as intake-and-route (clarifying questions, hand-off to the maintenance team, confirmation SMS afterward) rather than troubleshooting the issue. Since behavior is configurable, treat maintenance depth as a decision you make during onboarding, not a given.

To be clear as day about what Super is and isn’t: it is not a phone platform. There are no seats, softphones, or user licenses for your staff; it answers your main line, resolves what it can, and transfers the rest to your team on whatever phone platform they already use. That makes the natural architecture for an ops-driven PMC a pairing: a phone platform from bucket one carrying your team (Aircall, if call data flowing into your ops stack matters), with Super as the front-desk specialist taking the first ring. You would run Super instead of that platform’s own voice agent, not alongside it. Haven AI (usehaven.ai) is the same shape of product and the same rule applies (a specialist, not a phone platform): Y Combinator-backed with Evernest on the client list, but quote-only and genuinely early-stage [S32]. Both are worth a demo if a PM-trained receptionist is what you’re after.

And then there’s the heavyweight. EliseAI (eliseai.com) is the enterprise name in this category: conversational AI across text, email, chat, and voice, whose VoiceAI answers leasing and resident calls around the clock, books tours straight into the calendar, handles payment, renewal, and maintenance calls, and logs every interaction into EliseCRM, the company’s own AI-first CRM [S49]. (Its VoiceAI page says 33 languages; its homepage says seven. We’ve flagged the discrepancy.) Elise is a different shape from Super and Haven: not a receptionist you bolt onto your stack but a platform that wants your whole renter-communication funnel, CRM included, from a company at another order of magnitude, with a $2.2 billion valuation and a reported $200 million in annual recurring revenue built on large multifamily portfolios [S49, company-reported]. Two things put it in this guide anyway: it now sells an explicit single-family rentals solution, which means it’s coming down-market toward the operators this guide serves, and it publishes no pricing at all: no rates, no tiers, no floor. Third-party reports put typical contracts in the dollars-per-unit-per-month range with five-figure annual minimums; we can’t verify those numbers and you should treat them as directional only [S49]. Our taxonomy rules apply unchanged: it’s a specialist, not a phone platform (your team gets no seats or softphones), and the deeper your funnel wires into EliseCRM, the bigger the switching cost when you leave. At the scale where Elise makes sense, “get the all-in number in writing” stops being advice and becomes procurement.

08 / Connectability

🔌 The score most buyers never check

We build automations on top of phone platforms for a living. A phone call is data: who called, about which property, what they needed, what happens next. If your phone platform can hand that data to the rest of your stack automatically, a maintenance call becomes a work order without anyone typing; in our builds, that destination is a monday.com workspace. Four criteria, each out of 5: open API and webhooks, native integration catalog, automation platform support (Make, Zapier, n8n), and AI readiness including MCP adoption.

Criteria (out of 5)AircallRingCentralZoom PhoneDialpad
Open API and webhooks5543
Native integration catalog5423
Automation platform support5433
AI readiness4354
Connectability score19/2016/2014/2013/20

Scoring basis: API documentation review, integration catalog counts from vendor sites [S2, S3, S9, S21], automation platform module depth on Make and Zapier, and announced AI architecture [S6, S7]. The facts are sourced; the weighting is our professional judgment.

Aircall (19/20)

The clear winner and the reason it earns its premium price. The API is clean and well documented, webhooks cover every call event, the native catalog is the deepest at this tier, and every major automation platform supports it well. When we build automated workflows for a PMC, Aircall gives us the least friction and you the lowest build cost. The only point off: its AI agents are still a closed system rather than an open one you can extend.

RingCentral (16/20)

A mature, enterprise-grade developer platform and a large catalog. It loses points on developer experience. Everything is possible, but builds take longer and cost more than the same workflow on Aircall. If you already run RingCentral, the connectivity is there. We just wouldn't pick it for connectability alone.

Zoom Phone (14/20)

The interesting one. Its integration catalog is thin, and connecting it to your operations stack today means custom work. But it's the only platform of the four with native MCP support [S6], and its AI receptionist is the most mature [S7]. Our read: weakest connectivity today, best positioned for where AI is going. If Zoom builds out the catalog, this score changes fast.

Dialpad (13/20)

Deserves more AI credit than most comparisons give it. Real-time transcription and summaries are included in the $15 base plan, which no one else matches [S13]. It still loses points where it counts for automation: API keys are only available on Pro and Enterprise at all [S36], CRM connections are gated behind the Pro tier, webhook coverage is the shallowest of the group, and AI voice agents don't have a price you can learn without a sales call. Great AI for humans reading a dashboard. Weak AI for systems talking to systems.

🛠️ For custom builds: what the four APIs actually expose

We read all four developer platforms end to end. The scores above hold; here is what a builder actually gets, from each vendor’s own documentation. These are documented capabilities, not hands-on tests.

Aircall [S3]

The differentiator is Conversation Intelligence as an event stream. Transcripts (live during the call and complete afterward), sentiment, summaries, topics, action items, and predicted CSAT all arrive as webhook events, and its AI Voice Agent can be triggered and monitored via API. Two constraints shape the architecture: 120 requests/minute, and only six months of call history via API, so build webhook-first and archive as you go.

RingCentral [S37]

The broadest surface, including the only documented API-level call supervision, in-browser WebRTC calling, WebSocket event streaming, five-plus official SDKs, and a free sandbox. Its AI family (speech-to-text, diarization, summaries) is offered as usage-priced APIs. The tax is onboarding: app registration, scopes, and tiered limits.

Dialpad [S38]

A better API than its reputation, behind a worse door. Once on Pro: 1,200 requests/minute, call control including park and IVR calls, bulk and scheduled SMS, and transcript endpoints. But no API keys exist below Pro [S36], and there is no AI event stream; transcripts are fetched, not pushed.

Zoom Phone [S9]

A strong data plane and a thin control plane. Rich call detail records, recording download URLs delivered by webhook, voicemail events, and provisioning for users, queues, and auto-receptionists make it excellent for log-everything builds; third-party in-call control is barely documented, and confirm the account-tier requirement before promising a build on a lower-tier account.

Which API, in practice. For most PMC builds the real shortlist is Aircall versus Zoom (RingCentral is a complexity tax you pay only when you need its unique capabilities, and Dialpad’s door is gated). The cleanest way to choose is the job description: Aircall’s API is a workflow engine; Zoom’s is a filing cabinet. Two real builds show the line:

“Every call becomes a work order with the transcript and sentiment attached, in real time, in your PMS or monday.com workspace.” Only Aircall does this today, because the AI artifacts arrive as webhook events. On Zoom you get notified that a recording exists, download it, and assemble your own transcription and analysis: buildable, but you are constructing the intelligence layer yourself.

“Log every call into the operations system and provision phone setups across a portfolio.” Zoom is genuinely good here: rich call detail records, recording URLs pushed to you, and queue and auto-receptionist provisioning at scale, on cheaper seats.

Developer friction splits the same way: Aircall is an afternoon (API key, Basic auth, subscribe to webhooks); Zoom is a proper app setup (OAuth scopes, plus the account-tier question above) before the first event arrives. And each side has one trap. Aircall’s six-month history window forces webhook-first architecture from day one; there is no backfilling later. Zoom’s is the unconfirmed Business-tier gate, which decides whether your build floor is the $16 seat or the $24.50 one. The rule that falls out: if the phone data needs to drive your operations, Aircall’s API justifies the seat premium by itself; if the data just needs to land somewhere, Zoom is sufficient and the total stays lower.

The one-line version for a PMC: logging calls into your operations system is achievable on all four; putting AI on the record as it happens is Aircall’s alone; embedded agent experiences belong to RingCentral; Zoom is the archivist.

09 / AI costs

🤖 The AI features that matter, and what they actually cost

Vendors use one word for three different products; know which one a pricing page is selling before comparing numbers. AI that documents (call intelligence): transcription, summaries, sentiment on calls your humans take; increasingly table stakes. AI that assists: caller context and live answer suggestions for your human during the call; the mode most buyers don't know exists. AI that answers (voice AI): receptionists and agents that pick up instead of a human; always a separate meter, never free. Four capabilities, priced very differently.

Dialpad AI AgentDialpad onlyUnpublishedQuote-only, credit-based per-conversation pricing [S13]

Watch the units: Quo’s per-call pricing beats everyone on short calls and loses badly on long ones, Super’s minute includes channels nobody else bundles, and RingCentral’s overage is the steepest meter on the table.

Two things jump out. First, sentiment analysis is cheap exactly once in this market: Aircall includes it in its $9/license AI Assist. Everywhere else it’s contact-center machinery: RingCentral wants $60 per user per month, and Dialpad, despite its AI-first branding, only sells sentiment inside Sell and Support, its $80-plus contact-center products. (Most published comparisons claim Dialpad includes sentiment at $15; Dialpad’s own help center says otherwise, and we checked.) Second, no one will tell you what Dialpad’s AI voice agent costs without a sales call, which for a small business usually means the answer is “more than you want to pay.”

What the full AI stack costs a 5-person PMC

The realistic monthly bill for a five-seat office that wants all four capabilities, assuming 300 AI-answered minutes per month. The math is shown so you can rerun it with your own volumes.

Estimated total~$317/month~$264 without sentiment; ~$564 with it~$170/month$75 + a sales call

All figures estimated from verified or corroborated unit prices; regulatory fees, taxes, and number charges excluded. For scale: a real August 2026 Aircall quote carried $4.98/user/month in recovery fees, about $25/month for this five-seat office [S47]; assume comparable recovery fees on any platform. Zoom’s voice agent estimate assumes linear pricing from the published $29.99/100-minute entry rate; Zoom publishes no volume tiers above 100 minutes, so treat the linear number as a ceiling [S7]. One caution on all voice agent estimates: these meters run on actual call volume, and PMC call volume spikes. Whatever platform you choose, set usage alerts on day one.

The shortest honest version of this table: Zoom is the right bill for the size you are; Aircall is the right system for the size you’re becoming.

10 / Rankings

🏆 Category rankings: who wins what

Averages hide the truth. Here’s every category ranked outright, based on the verified pricing and features above. Find the categories that match your operation and weight those.

Value for money

  1. Zoom Phone. $16 buys unlimited calling, unlimited texting, unlimited IVR menus, call queues, monitoring, recording, and AI summaries [S5]. Nothing else comes close per dollar.
  2. Dialpad. $15, a dollar less, with better AI intelligence included but fewer calling features and texting caps [S13].
  3. RingCentral. $25 (Advanced, the real starting tier) buys a deep platform, but fees and add-ons erode the value [S17].
  4. Aircall. The most expensive seat with the least included. You're paying for integration quality, not features per dollar [S2].

Call intelligence included at base (the AI that documents, not the AI that answers)

  1. Dialpad. Real-time transcription and summaries at $15 with no add-on [S13]. Still the strongest included package, though note sentiment is not part of it despite common claims [S10], and the $15 tier itself is a sealed box: no API access and no 24/7 support without Pro [S36].
  2. Zoom Phone. Summaries, voicemail task extraction, and voicemail prioritization included [S5]. No sentiment on Phone plans.
  3. RingCentral. Transcription included even on Core [S11]. Everything smarter costs extra.
  4. Aircall. Nothing at base. Every AI feature is a paid add-on unless you buy the $50 Professional tier [S16].

AI receptionist and voice agents

  1. Zoom Phone. The most mature product, the lowest entry price ($29.99/100 minutes, $24.99 annual), self-serve setup, and it works without Zoom Phone [S7].
  2. Aircall. Self-serve, transparent per-minute pricing published in its own billing docs [S1], and the agent takes in-call actions like scheduling. Bundles run $0.29 to $0.35/minute, above Zoom's entry rate (a July 2026 cut that briefly priced them below Zoom had mostly vanished from their pages within two weeks); you're paying for the in-call actions and the integrations, not the cheapest minute.
  3. RingCentral. Capable, now sold standalone for any phone platform at $49/month, but $0.50/minute past the included minutes is the most expensive metering here [S18]. A busy leasing line will feel it.
  4. Dialpad. Quote-only, enterprise-oriented [S13]. If you have to book a sales call to learn the price, it wasn't built for your size of business.

Automation and integrations (Connectability)

  1. Aircall (19/20). The cleanest API, deepest catalog, best automation platform support. The platform we'd pick to build on every time.
  2. RingCentral (16/20). Everything is possible; builds just take longer and cost more.
  3. Zoom Phone (14/20). Thin catalog today, but the only one speaking MCP, the standard AI systems are converging on [S6].
  4. Dialpad (13/20). Good AI for dashboards, weak plumbing for workflows.

Texting tenants and owners

  1. Zoom Phone. Unlimited SMS/MMS on the Unlimited plan [S5]. Full stop.
  2. Aircall. A correction, on the record (see the update log): earlier editions called this "effectively unlimited," citing Aircall's 13,000-segment monthly sending cap [S20, verified]. That cap is real, but it's a throughput limit, not an allowance. What you're billed, per Aircall's own charges documentation and a real August 2026 quote we reviewed: 250 outbound SMS segments and 50 MMS per user per month, pooled across the team, then roughly $0.01 per segment and $0.04 per MMS [S48, S47]. Yes, that's the same 250-included model we ding Dialpad for one line down. Aircall holds #2 on the tiebreakers: the allowance pools across seats, MMS is included, and the high caps still make it the platform for texting automation. But it's a cheap meter, not an open road.
  3. Dialpad. 250 messages per user included, then $0.008 each [S19]. Fine until your rent-reminder automation scales.
  4. RingCentral. 25 texts per user on Core, 100 on Advanced, 200 even on Ultra [S11]. For a texting-heavy PMC, disqualifying without its paid Business SMS Booster add-on, which the pricing page lists without a price [S11].

Call handling and routing

  1. Zoom Phone. Unlimited auto-attendants, ACD queues, barge/monitor/whisper/takeover, holiday routing, and call park on every plan, per Zoom's own pricing and features pages [S5, S22].
  2. RingCentral. Comparable depth, but automatic recording and monitoring start at Advanced [S11].
  3. Aircall. Strong queue and team workflow, though the power dialer and some depth sit on the $50 tier [S2].
  4. Dialpad. Covers the basics well. Advanced contact center routing lives in a separate $80+ product [S13].

Smallest operations (solo to ~3 people)

  1. Dialpad. One-user minimum on Standard [S13]. The only platform a solo operator can buy right-sized. (Pro requires 3 seats, same floor as Aircall.)
  2. Zoom Phone. No meaningful minimum, and the cheapest path to an AI receptionist [S7].
  3. RingCentral. Works, but you're buying more platform than you need.
  4. Aircall. The 3-license minimum means a solo operator pays $90/month for two empty seats [S2]. Skip it at this size.

Growing operations (multi-department, 250+ doors)

  1. Aircall. This is where the premium pays off: department workflows, call data flowing into your operations stack, analytics your team will actually use.
  2. RingCentral. The consolidation play. Phone, video, and chat under one vendor with enterprise controls.
  3. Zoom Phone. Scales fine on features, but you'll build your own integrations as complexity grows.
  4. Dialpad. The tier-gating and product-splitting that don't matter at 3 seats start to sting at 15.

Billing predictability

  1. Zoom Phone. Flat seat price, one add-on with a published rate. What you quote is close to what you pay. One catch: annual plans are billed as a single upfront charge, not monthly [S5].
  2. Dialpad. Flat and predictable, until you want the voice agent nobody will price publicly.
  3. Aircall. The AI pricing is published in unusual detail [S1], but the seat invoice is not the pricing page: a real August 2026 quote we reviewed adds a $3.99/user/month Compliance and Administrative Recovery Fee and a $0.99/user E911 Recovery Fee, about $5 per seat that appears on no public Aircall page, plus $0.03/minute inbound on toll-free lines [S47]. Industry-standard fees, the same class we flag on RingCentral below, but unpublished. Stack that on the published add-ons, minute meters, origination fees, and the 3-seat floor.
  4. RingCentral. Regulatory fees, overage charges, and add-on stacking make the invoice a monthly reading assignment [S17].

Zoom Phone wins five of nine categories, and if you’re keeping score at home, that surprised us too. It’s the best pure phone platform for the money in 2026. But notice which categories Aircall wins: automation and growing operations. Those are the two categories that determine whether your phone platform becomes part of an integrated operation or stays a standalone tool. Winning on price is about this month’s bill. Winning on integration is about how your business runs for the next five years.

11 / The crossover

💸 Where the cheap system stops being cheap

Below roughly 250 doors, Zoom’s category wins are the whole story: buy the $16 seat, add the $25 receptionist, keep the change. Above that line, the failure mode of the cheap system isn’t the phone. Calls connect fine. It’s what happens after the call ends.

A platform with thin integrations makes your team the integration. Every call that should become a work order, a guest card, or an owner note gets there because someone typed it. Run the math we use with clients: a 500-door operation fields roughly 25 to 40 calls a day across leasing, maintenance, and residents. At even two minutes of after-call data entry each, that’s 50 to 80 minutes of re-keying every day, roughly $440 to $700 a month of admin labor at $25/hour [estimated; rerun it with your own call counts]. The verified price gap between the Aircall stack and the Zoom stack for a five-seat office is about $147 a month. The labor gap swallows the price gap well before 300 doors and widens with every door after.

The re-keying is the cost you can see. The invisible one is worse: the after-hours leasing call that never became a tracked showing, the maintenance conversation with no record when an owner asks what happened, the pattern across a hundred calls that nobody spotted because the data only ever existed in someone’s memory. A missed lease is a four-figure loss that never appears on any invoice, which is why nobody budgets for it.

None of this repeals the advice above. Under 250 doors, or if you genuinely will not automate, buy on price and skip this section’s worry. Past that line, the cheapest seat is usually the most expensive decision on this page.

12 / The vision

🧭 The connected phone: our vision, made testable

Every comparison above measures what exists. This section states what we think a phone platform should be, because that belief shapes our recommendations and you deserve to see it stated rather than embedded.

The vision: a phone platform connected to all of your company’s data, where every call and text writes itself into the same system that holds your tenants, owners, work orders, and leases; where AI answers the calls it should and assists your team live on the calls it shouldn’t; and where the text thread and the phone call about the same leak land in the same workflow, organized at a glance. This is LaunchEngine’s vision. It’s what we build toward for clients, our Aircall relationship is disclosed throughout this guide, and a vision you can’t audit is just marketing. So here it is as a test you can run on any vendor, including ours.

✅ The five-part test

  1. 1

    Calls document themselves. Transcript, summary, and sentiment reach your system of record in real time, with no human re-keying (the AI-that-documents mode, delivered through the Connectability plumbing).

  2. 2

    AI can answer. A voice agent can take a branch of your phone tree, or the trunk (the AI-that-answers mode).

  3. 3

    AI can assist live. Caller context and suggested answers on your team member's screen during the call, so an owner's "what did we spend on that unit last quarter" gets answered on the call, not in a callback (the AI-that-assists mode, the one most buyers don't know exists).

  4. 4

    Texts ride the same rails. SMS gets the same AI handling and the same logging as voice (channel parity, requirement #6).

  5. 5

    You can rewire it yourself. Routing, workflows, and agents change from a settings page your office manager owns (requirement #7).

📋 The platforms against the test

TestAircallZoom PhoneRingCentralDialpad
1. Calls document themselves✅ Transcripts, sentiment, summaries arrive as real-time webhook events [S3]⚠️ You're notified a recording exists; you build the rest [S9]⚠️ Possible via usage-priced AI APIs [S37]⚠️ Transcripts fetched on demand, Pro+ only [S36, S38]
2. AI can answer✅ Voice agent, $0.29-0.49/min [S34]✅ Best generic receptionist, $0.25-0.30/min [S7]✅ AIR, steepest meter at $0.50/min overage [S18]⚠️ Quote-only [S13]
3. AI can assist live✅ AI Assist Pro, $49/license [S16]⚠️ Custom AI Companion add-on announced at $12/user [S6]⚠️ Conversational Intelligence, $60/user [S11]✅ Included on higher tiers [S13]
4. Texts ride the same rails✅ AI messaging agents priced per conversation [S35]; team texting 250 segments/user pooled, then ~$0.01/segment [S47, S48]⚠️ Unlimited SMS, but no AI texting [S5]❌ 25-200 SMS caps [S11]⚠️ 250 messages included, then metered [S19]
5. Rewire it yourself✅ Settings-page admin (see the 500+ recommendation below)✅ Good self-serve admin❌ Heaviest admin console here⚠️ Fine until the gated tiers bite

(Bucket three sits outside this table on purpose: a Twilio build passes any part of the test you’re willing to engineer and maintain yourself, which is the trap; the five parts are a checklist of the products you’d be re-implementing.) Read the columns and the conclusion falls out: Aircall is the only platform that passes all five today. That fact, not the partnership, is why it anchors our integrated-stack recommendations, and every cell above comes from the sourced findings earlier in this guide, so you can re-run the table yourself. Zoom is two paid add-ons and a catalog away, which is exactly the bet our outlook section makes. RingCentral has the parts but sells them as enterprise machinery. Dialpad documents beautifully and connects poorly.

🌳 Why a specialist can’t be the whole vision

Specialists pass this test only for the branch of the phone tree you hand them. RentEngine: Passes all five for the leasing branch and nothing else [S40]. Vendoroo: The same for maintenance [S33]. Super: Passes the answer test on your trunk with real PMS write-backs, but it doesn't assist your team live, and your team's own calls and texts still live wherever your platform puts them [S31]. SimpleVoIP CRM Connect: Passes the documentation test into AppFolio, but there's no assist mode, and its own voice agent is new and unpriced [S41]. None of this makes specialists wrong; it makes them partial, and exactly how partial depends on your configuration: which branch you hand them, and what happens to every conversation on the branches you don’t. The stack that fulfills the vision is a platform that passes all five, plus specialists wherever their depth beats the platform’s generic agent.

And one product proves this vision isn’t vendor marketing: Rent Manager’s rmVoIP already is the connected phone, natively, for shops on that PMS, with calls made inside the software and documented against the contact automatically [S23, S46]. The standard predates our stack preference. If your PMS ships it, take it.

⚖️ Where the vision loses

Honesty about the edges. Under roughly 250 doors, the connected phone is over-buying, and our recommendation stays Zoom or Dialpad on price. Platform-bound agents mean vision lock-in is real: build your flows on Aircall’s agents and they don’t move with you when you change platforms, which is taxonomy rule two, and it applies to our favorite too. And our outlook section argues that parts of this test become checkboxes on every platform by 2027, which means the durable asset was never the vendor. It’s the clean, connected data model you own. The vision is the destination; any vendor in this guide is this year’s vehicle.

13 / Recommendations

🎯 Our recommendations by company size

Solo operator or under ~250 doors

Dialpad Standard ($15) or Zoom Phone Unlimited ($16). Both include real AI, and neither forces you to buy seats you don't need. If you're truly solo and want AI answering built in without assembling pieces, Quo's $15 Starter with its included Sona agent is the cheapest complete package going [S28]. Otherwise add Zoom's standalone Virtual Agent Receptionist at $24.99 to $29.99/month if after-hours coverage is costing you leases, regardless of which phone platform you run [S7].

250 to 500 doors, dedicated office staff

The real question at this size is trajectory, not budget: are you staying this size, or building to grow? Staying: Zoom Phone Unlimited, 80 percent of the value at half the cost. Building: Aircall, which costs more this month and compounds every month after; it's the platform that passes all five parts of the connected-phone test above, and the one whose call data your operations stack grows around. The crossover section above prices exactly where that math flips.

500+ doors or multi-office

Aircall Professional, for the same reason it wins our growing-operations ranking and passes all five parts of the connected-phone standard above, plus one this guide should say plainly: ease of change. At this size your phone tree is a living thing. Offices open, after-hours coverage moves, an AI agent takes over a branch, seasonal routing changes monthly, and in Aircall those are minutes in a settings page your operations manager owns, from editing the phone tree to deploying and configuring an AI agent. That admin speed is an operating cost no per-seat price comparison captures, and in our hands-on work building phone stacks for PMCs the gap is not close. Choose RingCentral Advanced instead when its specific depth is the requirement: consolidating phone, video, and chat under one vendor, the highest SMS caps in this guide (200/user/month) [S11], or supervision workflows through its documented API [S37]. It's the deepest toolbox in this guide; it's also a heavier platform to administer, and you should demo both admin consoles with your own phone tree before deciding.

Every size

Skip metered plans entirely. PMC call volume is unpredictable, and metered billing turns a maintenance-heavy month into a surprise invoice.

The fine print that catches PMCs

  1. Get the all-in monthly number in writing. Base price plus regulatory fees plus the add-ons you actually need. Every platform here advertises a number lower than what you'll pay.
  2. Confirm SMS limits against your real volume. Count last month's outbound texts including automated reminders. Compare against plan caps and overage rates.
  3. Ask how number porting works and how long it takes. Moving your main office line is the riskiest part of any switch. Get the timeline committed before you cancel anything.

Frequently asked questions

The questions PMCs actually ask about phone platforms, answered from the verified research above.

Between $15 and $50 per user per month for the seat, depending on platform, plus $9 to $60 per user for AI features and $25 to $160 per month for AI call answering at modest volume. A realistic all-in figure for a 5-person office with full AI capabilities runs $170 to $564 per month depending on platform choice.
Zoom Phone US & CA Unlimited at $16/user/month includes unlimited SMS and MMS. Watch out for Zoom's cheaper $10.50 metered plan and RingCentral's Core plan, which cap texting at levels a PMC will exhaust in days.
Published rates in this comparison run $0.19 to $0.50 per minute at the extremes. Aircall charges $0.49/minute pay-as-you-go ($0.39 past 2,500 minutes), $0.29 to $0.35 on prepaid bundles, and advertises custom bundles from $0.19/minute at 10,000+ minutes; a roughly 25 percent cut published on July 30, 2026 had mostly vanished from their pages within two weeks, and if you see the lower rates ($130 and $550 bundles) in your session, that's a rate worth asking for by name. RingCentral charges $0.50/minute past its included allowance, billed in 30-second increments. Zoom's Virtual Agent Receptionist works out to roughly $0.30/minute at its $29.99/100-minute entry rate, or $0.25/minute with annual billing. LeadSimple's built-in AI voice agent is $0.40/minute past the minutes bundled in its seats (the July-published rate; the current pricing page no longer lists overage rates). Quo prices per call instead of per minute: $0.45 to $1.00 per AI-answered call depending on volume, with 10 free calls monthly on every plan. Super, the PM-specific AI receptionist, works out to roughly $0.40/minute at its published bundles, which also cover email and SMS. Dialpad and EliseAI do not publish rates.
Not in its phone plans. Sentiment analysis requires the Conversational Intelligence add-on (formerly RingSense) starting at $60 per user per month. Dialpad doesn't include it in its phone plans either, despite what most comparisons claim: Dialpad's help center places sentiment in its Sell and Support contact-center products. The cheapest route to sentiment on tenant and owner calls is Aircall's $9/license AI Assist.
Yes, and you now have two generic options plus the PM-native route. Zoom's Virtual Agent Receptionist launched as a standalone product in July 2026 from $29.99/month per 100 minutes ($24.99 annual) and works with any existing phone platform. RingCentral's AI Receptionist also sells standalone for any phone platform at $49/month with 100 minutes included; it costs more for the same allowance. For after-hours maintenance calls specifically, PM-native services like Latchel and Property Meld's MAX On-Call troubleshoot and dispatch rather than just answer and route. And for a PM-trained receptionist that covers phone, email, and SMS with PMS integration, Super starts at $415/month with 1,000 minutes included; Haven AI sells the same category quote-only; and EliseAI, the enterprise heavyweight now selling an explicit single-family solution, is quote-only too.
Dialpad: 1 on Standard, 3 on Pro. Zoom Phone: no meaningful minimum on standalone plans. RingCentral: sold from small teams up. Aircall: 3-license minimum on both published plans (25 on Custom), so the real entry price is $90/month.
Any of the platforms in this guide. They're all internet softphones, so an offshore VA logs into the desktop or mobile app and works your US number like anyone else; you pay the same per-seat price. In PM operator groups, Zoom ($16) and Quo ($15, with call recording and transcription included) draw the most praise for VA lines, Dialpad gets steady marks for reliability, and RingCentral works but is the platform whose billing draws the most complaints. Three practical notes: the VA's local internet quality matters more than the platform; skip Google Voice, it's a consumer tool and the inconsistency operators report is the product working as designed; and some VA staffing agencies bundle a phone line at $35/month or more, which is above every platform's retail seat price, so buy the seat directly and keep control of your own number.
No. monday.com's native Zoom integration covers meetings, not phone calls, and there is no built-in business phone. PMCs that run their operations on monday.com connect a phone platform from this guide through its API instead, which is where the Connectability scores earn their keep: with a platform like Aircall, every call, text, and voicemail can land in the monday.com workspace as an item against the right tenant and property, transcripts and all. That integration work is what we build at LaunchEngine.
You can, and for a PMC you shouldn't. Twilio's unit prices are the cheapest in this guide (numbers from $1.15/month, calls at $0.0085 to $0.0140 a minute, texts at $0.0083), but they buy parts, not a product: softphones, queues, voicemail, admin, E911, and A2P compliance all become your engineering and your on-call rotation. The savings versus a $15 to $16 seat disappear with the first hour of monthly maintenance. Use Twilio when phone capability is a feature of your software, like an SMS reminder bot or a custom voice experiment; buy a phone platform when it's your office phone.
Rent Manager is the only major PMS with a full built-in phone platform: rmVoIP makes and receives calls inside the software, auto-recorded to the contact's record. AppFolio, Buildium, and Rentvine all text natively but ship no staff phone. AppFolio's Realm-X Leasing Performer answers leasing calls with multilingual voice as of June 2026, but it's a leasing specialist, not a phone your team can call from. The step-zero table in the PM-native stack section shows all four side by side.
Almost never. Metered plans price around $10.50/user plus roughly $0.03/minute outbound. PMC call volume is spiky and inbound-heavy, and one maintenance-heavy month erases a year of savings. Every recommendation in this guide assumes unlimited domestic calling.

14 / The outlook

🔮 Where this market is going

Everything above is verified present tense. This section is our read on the next few years, labeled as exactly that: analysis, not verified fact.

The agent tier consolidates into the platforms. Every platform in bucket one now ships its own AI agent: Aircall’s voice and messaging agents, Zoom’s receptionist, Quo’s Sona, RingCentral’s AIR, Dialpad’s quote-only agents. As those mature, a standalone specialist survives only where its depth beats generic: Super’s PMS write-backs, Vendoroo’s maintenance data and human coordinators, RentEngine’s leasing data. Specialists that merely answer and route are competing with a checkbox on the platform’s pricing page, and checkboxes win on price. Expect some of the names in this guide to be features, or acquisitions, by the 2027 edition.

What doesn’t commoditize is the data model. All three AI modes are exactly as good as the data they can read and write. An agent with beautiful prompts and no access to the tenant ledger, the work-order history, or the listing calendar is a greeting. Connections and prompts are getting cheap; a clean, connected operational data model is not, and it compounds. So the durable question about any product in this guide isn’t “how good is the AI today.” It’s “what data can it touch, and where does the record live when this vendor is gone.”

Our doctrine, disclosed. (The testable version of this doctrine is the connected-phone standard earlier in this guide.) LaunchEngine’s position for our own clients: one platform that can do everything, with gaps closed by custom builds on its API rather than by adding vendors. The stacks in this guide are the present; the doctrine is the trajectory. Each specialist earns its place today where its depth beats the platform, and each is a candidate for absorption tomorrow. Whatever you buy, own your data model and your phone numbers. Every other decision on this page is reversible.

15 / About us

Where LaunchEngine fits

We build the operations layer that your phone platform should feed into, on monday.com: every call, text, and voicemail logged against the right tenant, property, and owner in a monday.com workspace, with AI handling the routine follow-ups. Whichever phone platform you choose, the question that matters most is what happens to the conversation after you hang up. If you want help thinking through which setup fits your operation, that’s a conversation we have with PMCs every week.

August 10, 2026 (LeadSimple's third move)LeadSimple's Phone + Inbox pricing changed for the third time in three weeks of watching: the $29 Core tier, removed between July 24 and July 29, is back, now as a shared-inbox-plus-IVR tier, with a $59 Pro tier carrying the ring groups, routing, recording, and the AI voice agent (600 minutes, 1,200 SMS, 45 AI minutes per user). The overage rates published in July (5c/minute, 2.5c/SMS, $0.40/AI minute) are no longer on the pricing page. The review, comparison table, FAQ, and S24 are updated; the buying advice is unchanged: the seat to compare against a phone platform is the $59 Pro. Same watch run, small print: KrispCall reworded its metering disclosure (now 'Pay per Minute Calling' and 'Pay per Segment' per tier); still metered on every plan, no substance change.
August 10, 2026 (EliseAI)Added EliseAI to the PM-native specialist category, verified against its own pages. The enterprise heavyweight of renter-communication AI (VoiceAI answering leasing and resident calls 24/7 into its own AI-first CRM) now sells an explicit single-family rentals solution, so it belongs in this comparison even though it publishes no pricing at all; third-party per-unit contract figures are noted as unverified. We also flagged a discrepancy on their own pages: the VoiceAI page says 33 languages, the homepage says seven. New source S49; the weekly watch now alerts if EliseAI ever publishes a price.
August 10, 2026 (the cut that wasn't)Aircall's July 30 AI Voice Agent price cut has mostly vanished from its pages. On August 10 we captured its pricing pages repeatedly in fresh sessions: the large majority now show the pre-cut rates ($0.49/$0.39 pay-as-you-go, $175 and $725 bundles, $0.19/minute custom floor), while the cut rates ($130/$550) still appeared in a minority of sessions the same day, which looks like price testing or a staggered rollback. Two details make sense in hindsight: Aircall's billing documentation carried the higher rates the entire time (what we had flagged as doc lag was the durable price), and the August 7 sales quote we reviewed (S47) was priced at the higher bundle rate throughout. The guide now cites the higher set everywhere, and every affected number is corrected: the AI cost tables, the five-seat stack total (back to ~$317/month), the crossover gap (~$147/month), the receptionist ranking note (bundles no longer price below Zoom's entry rate), and the August 7 advice to point your rep at the cut rates, which now reads the way it should have all along: this meter's price moves, so verify the live page the week you sign and get the all-in rate in writing. If your session shows the lower rates, screenshot them and ask for them by name. No rankings changed.
August 7, 2026 (a real quote)A reader-shared Aircall sales quote became our first reviewed-quote source (S47, customer identity withheld), and it corrected us once and confirmed us twice. The correction: we had called Aircall texting "effectively unlimited" based on its 13,000-segment sending cap; the billed allowance is actually 250 SMS segments and 50 MMS per user per month, pooled, then about $0.01/segment, the same 250-included model Dialpad uses (Aircall's own charges documentation confirms the allowance; S48). The SMS ranking entry and connected-phone test now say so. The additions: Aircall seat invoices carry $4.98/user/month in unpublished compliance/administrative and E911 recovery fees, now in the billing-predictability ranking and the stack-cost footnote. The confirmations: the $50 Professional annual seat, $6 extra numbers, $50 additional users, and the $250/1,000-conversation messaging bundle all matched this guide to the dollar, and the quote priced AI voice minutes at the pre-July-30 $0.35/minute bundle rate, which is exactly why this guide says to treat published tiers as a ceiling and point your rep at the current published rates.
July 31, 2026 (trajectory)Sharpened the 250-to-500 recommendation into the question it actually is: staying this size (Zoom) or building to grow (Aircall). No rankings changed; this compresses the crossover math, the growing-operations ranking, and the connected-phone test into one sentence a buyer can act on.
July 31, 2026 (buckets)Promoted the build-it-yourself path to a formal bucket three with its own membership test (nothing exists until you build it) and two paths through it: raw programmable telephony, and pairing Twilio's dial tone with a hosted agent harness, the configuration builders described to us in July. The guidance is unchanged: build features on Twilio, not your phone platform.
July 30, 2026 (vision)Published the connected-phone standard: our five-part test for where this market should go (calls document themselves, AI answers, AI assists live, texts ride the same rails, you can rewire it yourself), with every platform scored from the guide's already-verified sources, our analysis of why specialists pass it only for the branch you hand them, and the three places the vision cuts against our own recommendation. Our Aircall relationship remains disclosed; the test is designed to be re-run by anyone.
July 30, 2026 (audit)Full-guide coherence audit. Corrected the podium-finish tally (Zoom 7 and RingCentral 3, not 8 and 2), the crossover labor-cost range ($440 to $700, recomputed from its own inputs), and the FAQ cost ceiling ($564). Added requirement #7, "You can change it yourself," so the framework states the ease-of-change criterion our 500+ recommendation relies on. Fixed the overlapping recommendation brackets (250 to 500, then 500+). Cut an unpriced figure we couldn't verify for RingCentral's Business SMS Booster (the add-on is real; the price isn't published). The methods section now describes the weekly automated watch, and the freshness dates across the guide were brought current.
July 30, 2026 (recommendations)Rewrote the 500+ doors recommendation to lead with Aircall, aligning it with our growing-operations ranking (which Aircall already won) and naming the deciding factor we had underweighted: ease of change. At multi-office scale the phone tree changes constantly, and admin speed, editing routing, deploying and configuring AI agents from a settings page, is an operating cost per-seat price comparisons never capture. RingCentral remains the recommendation where its specific depth is the requirement (suite consolidation, the highest SMS caps at 200/user, API-level supervision), and we added the same ease-of-administration caveat to its review. Disclosure unchanged: LaunchEngine has a commercial relationship with Aircall, and this guide's rule is that every claim must survive that relationship ending tomorrow.
July 30, 2026 (PMS voice)A deeper pass on PMS-native phone capability, prompted by a reader push, corrected us twice. AppFolio's Realm-X Leasing Performer went generally available with multilingual voice on June 16, 2026, answering leasing calls natively; our earlier "chat and email-first, not voice" description was a month stale, and it's fixed with the new S44 sourcing. And both AppFolio and Buildium text natively (S43), so the channel their PMSs are missing is specifically voice, which the guide now says precisely. Also added Rentvine (chat, email, and text native, no calling; LeadSimple's direct integration is the documented phone path) and recast the bucket-one PMS row as a catch-all: Rent Manager's rmVoIP remains the only full PMS-native phone platform we've verified.
July 30, 2026 (naming)Renamed the taxonomy for clarity: bucket one is now phone platforms (was phone systems), and bucket two is now specialists (was layers), software that owns one job on your phone tree the way a leasing specialist or maintenance coordinator does on an org chart. Same buckets, same membership tests, clearer names. Also gave every platform its own row in the bucket-one table and moved Google Voice to an explicit exclusion note.
July 30, 2026 (evening)Added SimpleVoIP after an operator interview put it on our radar: a quote-only, managed phone platform with the deepest AppFolio integration in bucket one (CRM Connect, in the AppFolio Stack Marketplace) and a newly launched, unpriced voice AI (Simple Agent). Includes an interview-sourced real-world price of about $170/month for a four-number shop.
July 30, 2026 (later)Our first automated weekly price watch caught Aircall cutting AI Voice Agent rates roughly 25 percent the day it happened: pay-as-you-go $0.49 to $0.37 (and $0.39 to $0.29 past 2,500 minutes), the 500-minute bundle $175 to $130, the 2,500-minute bundle $725 to $550, and the custom floor $0.19 to $0.14. Aircall's own billing documentation still showed the old rates the same day; we flagged the inconsistency and recalculated stack totals ($317 to ~$288).
July 30, 2026Reframed AI into three modes (documents, assists, answers), added the channel-parity requirement, and published our market outlook.
July 29, 2026Added Twilio (the build-it-yourself door). Added findings from our conversation with Super and calls to its demo agent. Caught LeadSimple removing its $29 Core tier between our July 24 and July 29 captures; corrected same day. Added RentEngine.
July 28, 2026Published. Added Aircall's $0.19/minute volume floor and messaging-agent per-conversation pricing after a reader pointed at pages we had missed. Confirmed Dialpad Standard has no API keys and no 24/7 support. Added the API review for custom builds.
July 27, 2026Added the PM-native AI receptionist category (Super, Haven) and Vendoroo, with verified pricing where published.
July 24, 2026First full verification. Every price captured from live vendor pages and checkout flows. Caught Zoom's unannounced price increase ($16 Unlimited, $10.50 Metered, $20.50/$24.50 bundles) that most published comparisons still miss. Corrected Dialpad's sentiment claim against their own help center (Sell/Support products only, not the $15 plan). Verified Zoom's checkout-only Global Select price at $22, not the widely cited $20.
