Quo

Quo, formerly OpenPhone, is a shared phone system for small businesses where people and AI agents work together, with an AI phone agent called Sona that answers calls when the team cannot. Its homepage describes Quo as the phone system that brings every call, text, and customer into one shared place, so no opportunity gets missed, even after hours. Sona is the agent layer: it answers when the team is unavailable, captures the details the business needs from the caller, and hands the conversation to the team when it matters, rather than leaving the caller with voicemail. Around that agent, recorded calls come back transcribed and summarized, so no detail is missed and nobody has to take notes. The phone system itself is built for shared work: a business can set up a number in minutes, share one number across the team and stay aligned on the same conversations, and route incoming calls to the right person instantly. Analytics help the team spot issues before they cost the business, and calls and texts sync with the tools the business already uses. Quo states it powers conversations for more than 90,000 businesses, and its homepage names integrations and connections including HubSpot, Salesforce, Jobber, Zapier, Make, Pipedrive, Zoho CRM, Attio, Clio, Housecall Pro, Slack, webhooks, and HighLevel. It also offers one click connectors for Claude and ChatGPT, plus a public MCP server and an API that a business's own agent can read and act on, which sets it apart for teams that want their phone conversations available to their other AI tools. Number porting is presented as a guided switch, with step by step guidance, priority support during the transfer, and most customers staying reachable while the number moves. For a small business comparing AI phone agents, Quo is the option to shortlist when the priority is one shared number for the whole team, an AI agent that covers the gaps the team leaves after hours and at busy moments, and summaries and integrations that keep every call and text visible in the same workspace. Buyers should test Sona on their own common caller questions, confirm exactly what details it captures for their workflow, check how handoffs reach the team, and verify that the integrations they rely on are covered before moving a main number over.
