OpenPhone Alternatives: 9 Options With Verified Pricing

If you searched for OpenPhone alternatives, the first thing worth knowing is that OpenPhone no longer goes by that name. The company rebranded as Quo in 2025: same product, same pricing, same apps, new name. Older reviews still say OpenPhone and newer ones say Quo. They are one phone system.

The shortlist, by the job you are hiring for: Allo at $18 per user per month if you run a one-person shop and want AI included in the seat. CloudTalk at €19 if you want a single seat with serious international calling. RingCentral if you are growing into a full phone suite. And if calls get missed because nobody on your team can answer them, Rezora IO replaces the seat model with an AI voice agent at $289 a month plus $0.20 per conversational minute.

Every price below comes from the vendor's own pricing page, fetched the day this article published. Vendors that hide pricing behind a sales call are marked quote-only, and any figure we could not verify on the page itself is labeled reported.

The 9 OpenPhone alternatives at a glance#

What Quo gets right, and where the bill grows#

The honest starting point for a list like this: Quo's pricing is the most transparent in the category, and the $15 Starter (annual billing, $19 month to month) is the cheapest printed seat on it. There is no seat minimum, the shared inbox is genuinely good, and the 7-day trial needs no sales call. If you are leaving, leave for a specific capability. Cheaper is not on the table.

Where the bill grows:

• Sona's ceiling. The AI agent answers calls and takes messages, with 10 free calls a month on every plan. Past that, bundles run $25 to $199 a month and overage costs $0.45 to $1.00 per call by volume tier. Sona never dials out.
• The texting fees. A $19.50 one-time carrier registration, a $1.50 to $3 monthly messaging fee, and automated SMS at $0.01 per segment.
• Linear scaling. Per-user pricing means a ten-person team on Business pays $230 a month before any Sona bundle. Extra numbers cost $5 a month each.
• No tier above. There is no power dialer and no enterprise plan. Teams that outgrow the shared inbox have nowhere to go inside the product.

Our OpenPhone pricing guide itemizes every fee, including Sona's credit table.

The alternatives, compared#

1. Allo: the one-person shop pick#

Best for: a solo operator or pair whose missed calls are missed revenue.

Allo is the closest thing to Quo's buying experience on this list, with the AI already in the seat. The AI receptionist, appointment booking, call summaries, and transcripts all come with every paid plan, no add-on required. Starter is $18 per user per month on annual billing, one user only; Business runs $32 annual ($45 monthly) and adds native CRM sync. The 7-day trial is self-serve, porting is free, and new numbers span more than 80 countries. The one fee to know: a $24 one-time 10DLC registration for texting.

Better than Quo at: AI included in the seat price, where Quo meters Sona per call. Loses to Quo at: Starter is one user with yearly billing only, outbound SMS caps at 150 messages a day, and the company is young.

2. CloudTalk: the international single seat#

Best for: one-person shops and small teams, above all those dialing across borders.

The entry tier, Lite, is €19 per user per month billed annually with a single-seat floor, or €27 paid month to month. That makes CloudTalk one of three vendors on this list that will sell you one seat at a printed price, and the only one built for international routes. Starter and Essential (€25 and €29 annual) keep the single seat; Expert at €49 requires three and includes the power dialer, which otherwise adds €15 per user per month. The 14-day trial needs no credit card and ships with 50 AI voice agent minutes.

The AI story is modular. Agents start at $99 a month for 200 minutes, conversation intelligence adds €9 per user, and the AI Specialist tier at €349 covers 1,000 minutes. Better than Quo at: international infrastructure, call-flow building, and a working dialer. Loses to Quo at: the add-on stack can double a small bill fast.

3. JustCall: the dialer-and-SMS pick#

Best for: sales teams of two or more that want outbound dialing and texting in one tool.

JustCall prints its ladder: Team at $29, Pro at $49, and Pro Plus at $89 per user per month, billed annually. Every plan carries a two-license floor, which puts the smallest possible account at $58 a month. Each tier pools 1,000 minutes a month for calls in both directions, caps SMS at 500 to 1,000 segments per user by plan, and includes two free numbers per account. The AI voice agent meters separately: $0.99 a minute pay as you go, or $99 for a 100-minute bundle and $249 for 300.

Better than Quo at: outbound tooling and SMS volume. Loses to Quo at: the two-seat floor shuts out true solo buyers, and the useful features sit in the upper tiers.

4. Aircall: the integration-heavy floor pick#

Best for: support and sales teams from three to fifty seats, wired into a CRM.

Aircall's pricing page renders no dollar figures without JavaScript; the plan names and a three-license minimum are visible, and the reported figures are $30 for Essentials and $50 for Professional, per license each month on annual billing. That puts the smallest account at $90 a month, and our Aircall pricing guide has the full stack. The AI voice agent gets 50 free minutes each month (100 more at signup), then a reported $0.49 per minute.

Better than Quo at: the integration catalog, IVR, and queue depth. Loses to Quo at: the three-license floor, and a pricing page that would not show us a number.

5. RingCentral: the suite you grow into#

Best for: teams of ten or more that want desk phones, video, and fax under one contract.

RingCentral publishes its add-ons and hides its seats. The plans page prices the AI Receptionist add-on from $39 monthly and Conversational Intelligence from $60, while RingEX seat pricing sits behind a user-count selector. The reported ladder, cross-checked in our RingCentral pricing guide: Core $20, Advanced $25, Ultra $35 per user per month with annual billing. The 14-day trial covers up to 20 lines but excludes SMS.

Better than Quo at: everything a thirty-seat floor needs, from desk-phone support to an enterprise tier. Loses to Quo at: price transparency, since the add-on stack is how a $20 seat becomes a $60 one. If the suite is more than you need, our RingCentral alternatives guide prices the smaller options.

6. Dialpad: quote-only, AI-forward#

Dialpad's pricing page publishes no dollar figures today: plan names, "Talk to sales" buttons, and AI Agent conversation-credit pools with no rates attached. The reported Connect ladder (Standard $15, Pro $25 per user per month) is documented in our Dialpad pricing guide, and Pro carries a three-seat floor. If AI calling is the reason you are shopping, our Dialpad alternatives comparison prices the dedicated AI market against it.

Strong transcription, a credible AI roadmap, and no way to learn what a seat costs without talking to sales. In a category where Quo prints everything, that is a strange way to buy a phone system.

7. Kixie: quote-only, outbound-first#

Kixie is the second quote-only vendor on this list: plan tiers called Professional, Single-Line PowerDialer, and Multi-Line PowerDialer, unlimited US and Canada minutes, a 7-day trial with no card, and no published rates. Reported seats run $35 to $95 a month per user (our Kixie pricing guide keeps the sources), and AI human detection sits behind a premium add-on.

If you run an outbound floor wired into a CRM, Kixie earns a demo slot. Everyone else can treat the missing price page as the answer it is.

8. Smith.ai: pay per answered call#

Smith.ai's AI receptionist pricing drops the seat model entirely: free for 25 calls a month and $3 each after, Pro at $150 a month for 75 calls ($2.00 apiece), bundles that drop the rate to $1.67 at volume, and enterprise from $500. It is month to month, and a 10% spam allowance lets you strike junk calls from the bill.

This is the right shape when inbound answering is the whole problem. There is no dialer and no outbound: you are buying answered calls, and the free tier is a genuine way to test whether that is enough.

9. Rezora IO: when the phone system is not the problem#

Some teams shopping for an OpenPhone alternative do not have a phone-system problem. They have a coverage problem: leads come in, nobody calls back fast, and voicemail does the follow-up. A different seat-based phone system leaves that exactly as broken as it was.

Rezora IO is an AI voice agent, a different category from everything above. It calls a new lead back in seconds, figures out on the call whether the caller belongs on your calendar, and books the appointment itself. Inbound answering runs on the same agent. The agent earns its keep mid-call because Rezora IO trains its own hosted models (supervised fine-tuning, then preference optimization) on real sales conversations instead of prompting a generic one. There are no prompts to write and no seats to buy: one plan at $289 a month plus $0.20 per conversational minute, billed only while the AI is talking, month to month. It connects to HubSpot, GoHighLevel, and Zapier, and Cal.com syncs bookings to Google, Outlook, and Apple calendars. Enterprise plans, including custom training on your own call data, are available.

If what you needed was a cheaper shared inbox, buy one of the seats above. If what you needed was every lead answered and worked, that is the category jump.

When staying on Quo is the right call#

Stay put if your team is under ten seats and the shared inbox is the thing you use all day. Quo's $15 Starter is the floor of this entire list, Sona covers basic answering for 10 calls a month, and porting out costs you a day of attention for zero gain.

Stay, too, if your frustration is the rebrand itself. A new name and a new app icon changed nothing about the product. The reasons to leave are specific: you need a power dialer, you need desk phones, you need AI that dials out, or your headcount just crossed thirty. Anything else is shopping for its own sake.

FAQ#

Is OpenPhone the same company as Quo?#

Yes. OpenPhone rebranded as Quo in 2025. The product, the pricing, and the apps are one system under a new name. Comparison pages that pit Quo against OpenPhone are comparing a company to itself.

Can I keep my phone number when I switch?#

Yes. Number porting is standard across every vendor on this list, and Allo explicitly ports for free. The practical path: sign up, get a temporary number, submit the port request with a copy of your current bill, and keep the Quo account live until the transfer completes.

What is the cheapest OpenPhone alternative?#

For a single seat at a printed price, nothing undercuts Quo's $15 Starter. Allo at $18 per user per month (annual billing, one user) is the closest, and it includes the AI receptionist that Quo meters separately. CloudTalk's €19 Lite is the next rung. Below those, the only cheaper option is Smith.ai's free tier at 25 answered calls a month, which is a different product shape.

Which OpenPhone alternatives include AI in the seat price?#

Only Allo, which bundles the receptionist, booking, summaries, and transcripts on every paid plan. Everyone else meters AI: Sona bundles from $25 on Quo, CloudTalk agents from $99 for 200 minutes, JustCall at $0.99 per minute, a reported $0.49 per minute on Aircall, and RingCentral's receptionist add-on from $39 a month. Rezora IO and Smith.ai skip the seat model and price the AI as the product itself.

Is OpenPhone still worth it in 2026?#

For solo operators and small teams that want a shared business number with a clean inbox, yes: the pricing is printed, there is no seat minimum, and the trial is self-serve. The case against staying is specific, never general: outbound dialing, desk phones, enterprise features, or AI that does more than answer.
