Zoom Phone (US & Canada Unlimited) review 2027

What problem does Zoom Phone solve?

Zoom Phone is phone service bolted onto the meeting app your team already opens every morning. That is the whole pitch, and it is the reason this system finished second of eight business phone systems we tested. If your staff already run their days inside Zoom, adding a phone plan costs $15 per user per month, gives you unlimited calling to the US and Canada, and removes one more application from the desktop.

Our verdict: for a team already living in Zoom, adding phone is cheap, sounds good and removes an app. Businesses with complex call routing will outgrow the auto-attendant. That is the trade you are making. The value story is strong, the routing story is not.

How did we score Zoom Phone?

• Call quality & reliability — 26 of 30. We blind-scored 40 recorded calls per system on the same connection, then tracked dropped calls, jitter under load, and the provider's published uptime.
• Features — 19 of 25. Auto-attendant, ring groups, voicemail transcription, SMS, video meetings, call recording, analytics, and what sits behind a higher tier.
• Setup & admin — 14 of 15. Time from sign-up to a working number, porting an existing number, the admin console, desk-phone support.
• Integrations — 9 of 10. CRM, helpdesk, Microsoft and Google integration, and the API.
• Value — 17 of 20. Monthly cost for five users on the plan our office actually needed, at annual billing, including fees and taxes we were quoted.

Setup was the near-perfect category. Features was where the points went missing, and the auto-attendant is the reason.

Where Zoom Phone stands out

The measured results back up the price. Call quality scored 4.4 out of 5 in our blind listening test. A working number was live 15 minutes after sign-up. Five users on the entry plan came to $75 per month, which is the best price-to-quality ratio in this test.

The workflow wins matter as much as the numbers. Calls escalate to a video meeting in one tap, so a support call that needs a screen share does not need a second tool. AI Companion writes voicemail and call summaries, which means nobody on the team has to listen back through a four-minute message to find the callback number. And there is nothing new to learn if the team already uses Zoom — the interface, the contacts and the meeting links are all where they already were.

How does the technology work?

Zoom Phone is a VoIP service, which means calls travel over your internet connection instead of a traditional phone line. A desk phone or the app converts your voice into data packets, sends them to Zoom's network, and Zoom routes them to the public phone network so the person on the other end hears a normal call. AI Companion sits on top of that stream: it converts speech to text during or after the call, then produces a written summary and pulls out action items. Because the call already runs through Zoom's servers, transcription and summaries need no extra hardware or third-party service.

What you actually get

The entry plan is $15 per user per month. Five users cost $75 per month. Unlimited calling covers the US and Canada. Business SMS is included. Video meetings run through Zoom Meetings rather than a separate product. Call recording works ad-hoc and automatically. Voicemail transcription arrives with AI Companion summaries. The published uptime SLA is 99.99%.

On the hardware side, this is a softphone-first system: the app is the phone, and desk phones connect over the network rather than a copper line. That is why setup is measured in minutes — there is no wiring, no punch-down block and no on-site technician. Porting an existing number is handled in the admin console.

How it compares to the competition

RingCentral scored 8.6 and costs $20 per user per month, or $100 for five users. It took the best call quality in our test at 4.6 out of 5, commits to 99.999% uptime, and carries an integration for nearly everything. Zoom Phone is cheaper and simpler; RingCentral is deeper and more reliable on paper.

Nextiva scored 8.4 at the same $20 entry price and $100 for five users, with 4.5 out of 5 call quality and the best support in the test — a real person, quickly, who fixed our porting problem in one call. Zoom Phone's support is ticket-first, and that gap is real.

Dialpad scored 8.3 and matches Zoom Phone exactly on price: $15 per user, $75 for five users. Its live transcription is accurate enough to read instead of listening, with real-time coaching prompts for sales and support calls, and it publishes 100% uptime on Pro and above. Zoom Phone counters with 4.4 versus 4.3 call quality and the one-tap video escalation.

8x8 Work scored 7.8 at $24 per user and $120 for five users, with unlimited calling to 14 countries on X2 and video meetings up to 500 participants. Ooma Office also scored 7.8 at $19.95 per user and $99.75 for five users, with no contract and hardware that works out of the box, but video, recording and transcription only arrive on Pro and above.

Where Zoom Phone falls short

Call-routing depth is where it lost. The auto-attendant is basic next to RingCentral or Nextiva, so a business with complex call flows, multi-level menus or heavy ring-group logic will hit the ceiling quickly. The full experience also requires a Zoom Workplace licence alongside the phone plan, which is a cost the $15 headline does not show. Support is ticket-first, which is a step behind Nextiva's phone support. And the features score of 19 out of 25 reflects exactly that: the essentials are present, the advanced routing is not.

Is it good value?

At $15 per user per month, five users cost $75 per month — the lowest five-seat figure among the systems we tested, tied with Dialpad. Value scored 17 of 20, and the only reason it is not higher is the Zoom Workplace licence requirement for the full experience. For the money, you get unlimited US and Canada calling, SMS, video meetings, recording, voicemail transcription with AI Companion summaries and a 99.99% uptime SLA.

Who should buy Zoom Phone?

Zoom-first companies watching the budget. If your team already opens Zoom every morning, this is the cheapest way to put phones on their desks without teaching them a new app, and the call quality holds up at 4.4 out of 5. If your business runs complex call routing, look at RingCentral or Nextiva instead — you will outgrow the auto-attendant here.
