Autessa Phone & Texting vs Quo (formerly OpenPhone)

Autessa Phone & Texting as a Quo (formerly OpenPhone) alternative

Autessa Phone & Texting is a business phone system for people and AI voice agents, built into the Autessa platform. Quo, formerly OpenPhone, is a shared business phone for small teams, with Sona, an AI agent that answers calls in English. Autessa adds agents you build yourself: they place calls as well as answer them, speak English or Spanish, can use a cloned voice, and take card digits on the keypad out of the AI's hearing.

Where Autessa wins

Why teams pick Autessa over Quo (formerly OpenPhone)

AI that dials as well as answers

Agents with real range

Build as many voice agents as you need, in English or Spanish, with tools, your knowledge and an instant voice clone.

Sensitive details stay safe

Secure keypad capture keeps card digits out of the AI’s hearing, and Call Redaction removes personal details from recordings.

Ask Autobot for a new call flow step, inbox view or text rule and it changes the app, code and all.

Calls and texts for your agents

Through the Autessa MCP, Claude or your own agent can search calls, read transcripts and act on your numbers, call flows and threads.
