Zoom Phone adds cloud calling to the Zoom platform, so teams make and receive calls, check voicemail and route calls from the same app they use for meetings. Plans are tiered, with metered and unlimited options in many regions, and a trial available.

The value is highest for organizations already on Zoom, since calling joins meetings without a second app. Standalone phone buyers should compare dedicated providers. For Zoom teams, Zoom Phone is the natural pick.

How we picked these

We compared official feature pages, pricing pages and public documentation for each service, and favored services that are actively sold and supported in October 2026. We mixed all-in-one platforms, small business phones and solo options so the list covers solo owners through large teams. Prices change by region and plan, so where pricing varies we say so and point to vendor pricing pages rather than quoting figures that may shift.

How to choose a VoIP service

Start with team size and tools: Zoom or Google Workspace teams get value from matching phone services, while others should weigh all-in-one platforms against simpler phones. Next, check number porting and coverage: confirm you can keep existing numbers and reach the countries you call. Finally, test call quality on your actual internet connection during a trial, since bandwidth and routing affect every provider.

Test before you port numbers

Run a trial with a new number first, test call quality at peak hours, and check voicemail, routing and mobile apps. Port existing numbers only after the trial proves reliable, since porting back takes time.

Test call quality at peak hours before committing. Run trial calls during your busiest period, on wifi and on mobile data, and check for delay, echo and dropped audio. Quality problems usually come from local network setup, not the provider, so test with a wired connection and a quality headset too. A provider that sounds great in a quiet demo can struggle on a busy office network.

Frequently asked questions

What is VoIP?

VoIP, or voice over internet protocol, carries phone calls over the internet instead of traditional phone lines. It lets you make and receive calls from apps, desk phones or browsers, with features like call routing, voicemail transcription and analytics.

Do I need special hardware for VoIP?

No. Most VoIP services work from apps on your computer or mobile phone, with optional desk phones for offices that want them. A stable internet connection and a headset matter more than hardware.

Can I keep my existing phone number?

Most providers support number porting, letting you move existing business numbers to the new service. Check porting support for your number type and country before signing up, and run a trial first.

Which VoIP service is cheapest for small teams?

Google Voice at 10 dollars per user per month and Phone.com entry plans suit small budgets, while Grasshopper suits solo owners. Compare total costs including taxes, fees and any hardware before choosing.

Does VoIP work during an internet outage?

No, not on its own. VoIP needs an internet connection, so an outage stops calls unless you have a backup like mobile failover, call forwarding to mobile numbers, or a secondary connection. Set up automatic forwarding to a mobile number before an outage happens, and test it quarterly. Businesses that cannot miss calls should keep a mobile backup plan and a backup internet connection for critical staff.
