Ooma Office alternatives: Google Voice, FreePBX, Asterisk, Quo (formerly OpenPhone) and 2 more. Prices and licenses checked October 25, 2026.

Verdict:Ooma Office lists Essentials at $19.95, Pro at $24.95 and Pro Plus at $29.95 per user per month with no contract, plus custom Enterprise pricing, and monthly taxes and fees on top. It mentions no free trial. Most alternatives here undercut that: Dialpad Standard at $15, Quo Starter at $15 billed annually, and Grasshopper from $14 a month. Google Voice is the only genuinely free hosted option, and it only fits solo use or a Workspace team, since its free plan needs an existing mobile number. FreePBX and Asterisk cost nothing in licenses but need a server, a SIP trunk and someone who will keep the system patched; a PBX that is exposed to the internet and left unattended is a common target for toll fraud. The trade-off with leaving Ooma is hardware: Ooma has a long history with desk phones and virtual receptionists, and app-first tools such as Quo and Dialpad assume staff use laptops and mobiles. Before you port numbers, check that the new service supports your existing number and your fax or alarm lines, if you have any, and ask whether texting and call recording are included in the plan you price.

Texting is capped at 250 messages a month on Pro and 1,000 on Pro Plus, and monthly taxes and fees come on top of every plan price.
