ChatGPT can look things up, write your email, and plan the week. It cannot ring the tyre place and ask what a set of four costs fitted. CosVoice is the phone it is missing: a real number in your area code that it can call from, answer on, and report back through.

In ChatGPT, add https://cosvoice.com/mcp as a connector. A CosVoice page opens, you sign in and press Allow. There is no key to paste.
Say what you want in a sentence, including what to accept if the first answer is no. ChatGPT asks the line; the line does the talking.
Plain sentences. The line works out the conversation.
“Call Osteria Mozza and get a table for two on Friday at 7:30. Take 7:00 to 8:30 if that's gone.”
“Ring the dentist and move my Thursday cleaning to an afternoon next week.”
“Call the pharmacy and find out whether the refill is ready and what it costs.”
“Phone the landlord about the leak, and tell me what they said.”
ChatGPT gets an id straight away and the write-up when the call ends. Ask it to check back, or let CosVoice wake it when the call is done.
The person your line rang can ring back and reach the same assistant, with your standing instructions already in place.
The same line connects to Claude, Cursor, or a Grok Bot. Connect whichever you happen to be using.
No. ChatGPT writes the brief; the CosVoice line holds the conversation in a natural voice, then hands back the outcome, the details, and the transcript.
You need a version of ChatGPT that supports connectors. If yours does not, you can still place calls from your CosVoice dashboard and read the write-ups there.
No. Calls use your CosVoice plan's minutes, whichever assistant asked for them. Try it for $3 once: a number and 10 minutes of calls to use over 14 days.
No. The line never reads out a card number or agrees to a charge, so the most it commits you to is a booking or an appointment.
Also for Grok Bot, Meta's Muse, and anything you write yourself.
