Ooma Office does not offer a permanent free tier, but a free trial is available for evaluation. The entry-level Ooma Office plan at $19.95 per month includes 35-plus features such as a virtual receptionist, mobile app, ring groups, and unlimited calling across the U.S., Canada, Mexico, and Puerto Rico. Upgrading to Ooma Office Pro at $24.95 per month adds call recording, voicemail transcription, a desktop app, and enhanced call blocking — features G2 reviewers frequently highlight as key upgrade drivers. Ooma Office Pro Plus at $29.95 per month further adds CRM integrations, call queuing, AI transcriptions, and an auto dialer for more advanced business needs.
