Quo, the business phone service previously called OpenPhone, includes its Sona AI agent on every plan, so a small team can get a shared phone system and AI answering from one vendor. Starter costs $19 per user per month, or $15 billed annually, with one local or toll-free number per user, calling and texting to US and Canadian numbers and voicemail transcripts. Sona runs on credits: each call uses 100 credits and every plan includes 1,000 credits, about 10 calls a month. More capacity is sold in tiers, from $25 a month for 40 calls to $199 for 600 calls, with overage falling from $1.00 to $0.45 per call. Business at $33 per user adds call transfers, phone menus, AI call summaries and HubSpot and Salesforce integrations. Quo ranks lower here because AI answering is an add-on to a phone plan rather than the core product, and 10 included calls will not cover a busy line.
