Every VoIP provider advertises its cheapest annual price and hides what you actually pay. This lines them up by real per-user cost, shows the month-to-month price right beside it, and works out the no-contract premium so you can see the true number before you sign anything.

Entry plans run about 8 to 30 dollars per user per month. The lowest advertised prices assume annual billing; month to month usually adds 5 to 12 dollars per user. Sort by per-user price then check the month-to-month column for the real figure.
Microsoft Teams Phone and Google Voice start lowest at 8 to 10 dollars, but need an existing Microsoft 365 or Google Workspace plan, and Teams needs a separate calling plan for real calls. Among standalone systems, Zoom Phone, Dialpad, OpenPhone and MightyCall are cheapest with unlimited US and Canada calling.
Ooma Office, Zoom Phone and Phone.com bill month to month at the same rate as annual, so there is no lock-in penalty. Use the No-contract filter to see only plans with little or no premium.
No. Every system here works as a softphone app on computers and mobiles. Desk phones are optional, and some providers rent or sell compatible IP phones if you want them.
