OpenPhone alternatives
OpenPhone is now Quo, priced from $19 a user with no seat minimum and a certified Claude connector. Six alternatives for teams who need more than a phone line.
Switch if calls need to drive a pipeline rather than sit in a call log, or if per-user pricing has outgrown the value. Stay if you want a simple business phone with no seat minimum, which is exactly what it is.
The short answer
- OpenPhone has rebranded to Quo, and its old pricing URL redirects. Starter is $19 per user monthly or $15 billed annually, Business is $33 or $23, and Scale is $47 or $35, with a seven-day free trial.
- It publishes a hosted MCP server and a certified one-click Claude connector, which is ahead of most business phone tools. Aircall's MCP position could not be confirmed and Twilio's server is in public beta and outside its SLA.
- It is a phone product, not a CRM. Calls arrive in the CRM as activity through an integration; they do not by themselves move a deal, set a disposition or create the next task.
How we compared these
Prices and capabilities come from each vendor's own site, checked in September 2026. The rebrand from OpenPhone to Quo was confirmed by the redirect on its own pricing URL rather than from a news article. Aircall is the one entry we could not price: its page renders every figure client-side and returned placeholders, so its row says so.
Evaluated from the vendor's own documentation and pricing, September 2026. We have not run it in production. Everything here is drawn from vendor sites rather than from operating a business phone system.
The comparison is arranged around cost per user, seat minimums, AI access and what happens to a call afterwards. Those separate this group. Call quality and core telephony features are broadly comparable across all of them.

The field, ranked for a team leaving OpenPhone
1. Close
The move when the calls should be sales activity rather than phone activity: $9 a user annually for a CRM with calling built in, dispositions on the record, sequences beside it, and a well-scoped MCP server. Best for: sales teams. Not for: a shared business line or support queues.
Read more2. Aircall
The step up to a real phone system with queues, routing and supervisor tooling. Note the three-licence minimum on its main plans, and that we could not verify its prices from its own site. Best for: teams of three or more running a call floor. Not for: one or two people.
Read more3. Stay on Quo
Correct for most small teams. No seat minimum, $15 a user annually, a seven-day trial, and better AI access than nearly any competitor here. Best for: small businesses who want a shared phone that works. Not for: teams whose calls need to move a pipeline.
4. HubSpot
Calling on its higher tiers with native logging against the contact, and a free tier for two users at the bottom of the ladder. Best for: teams already running HubSpot who want fewer vendors. Not for: heavy call volume, where a phone-first tool does telephony better.
Read more5. Twilio Voice
The raw telephony underneath much of this market, at $0.0140 a minute for US outbound and numbers from $1.15, with no per-user charge at all. You build the interface. Best for: teams with engineers. Not for: anyone who wants a finished product.
6. SalesCrew
Not a phone product, and it would be misleading to rank it as one. Outbound calls through Vapi are logged against contacts today; phone numbers, SMS, inbound routing and a browser softphone are on the roadmap and not shipped. Best for: teams whose problem is that calls never become pipeline. Not for: anyone who needs a working phone line, which is the entire reason to buy this category. New product, no third-party reviews, no mobile app. Disclosure: SalesCrew is our product.
Read moreWhen to stay on Quo, formerly OpenPhone
Stay because it does one thing properly. A shared business phone number with a good mobile and desktop experience, no seat minimum, and a price that starts at $15 a user annually is a complete answer for most small teams. The CRMs on this page do calling as a feature beside their real job, and it shows in the day-to-day experience of actually using the phone.
Stay for the AI access, which is better than the category norm. A hosted MCP server plus a certified one-click Claude connector means an assistant can work with your calls and messages today, with no integration work. Aircall's position on this could not be confirmed and Twilio's own server is still in public beta and explicitly outside its support terms.
Stay because number portability is the real cost of leaving. Your number is on invoices, in customers' phones and in search results. Moving it works, and it takes coordination and carries a window where something can go wrong. That risk deserves a better reason than a few dollars a seat, and it is why phone systems get replaced far less often than the software around them.
Questions
- Is OpenPhone still called OpenPhone?
- The product has rebranded to Quo. Its old pricing URL now redirects to quo.com, though the site footer still names OpenPhone Technologies as the company. Anything you read referring to OpenPhone pricing is describing the same product under its previous name, which is worth knowing when comparison articles disagree.
- What does it cost?
- Starter is listed at $19 per user per month billed monthly, or $15 billed annually at $180 a year, as of September 2026. Business is $33 monthly or $23 annually, and Scale is $47 or $35. There is a seven-day free trial. Per-user pricing with no seat minimum is the shape, which suits small teams well.
- Does it work with AI assistants?
- Yes, and unusually well for a phone product. It publishes a remote MCP server at mcp.quo.com and a certified one-click Claude connector. Among business phone tools that is ahead of the field; several competitors publish nothing, and Twilio's own MCP server is still in public beta and explicitly outside its support terms.
- Do calls end up in my CRM?
- Through integrations, as with every phone product. The distinction worth understanding is between a call appearing in a CRM as a logged activity and the call actually driving what happens next: a disposition, a stage change, a follow-up task. Phone tools do the first well and leave the second to whatever system owns the pipeline.
