open calls.Open Calls is the ChatGPT integration that makes real phone calls for you: ChatGPT sets it up from one prompt, quotes each call, calls the business and brings back a grounded answer.
Verified with ChatGPT Developer mode. The public ChatGPT directory listing is in review; until it is approved the prompt link does the setup.
An MCP connector added in ChatGPT (Settings › Apps & Connectors › Developer mode), signed in with your Open Calls account.
I am new to Open Calls (opencalls.dev), an AI phone-calling service. Walk me through setting it up and making a first test call with the free minute, one step at a time, waiting for me to confirm each step. 1) Account: I open https://opencalls.dev/signup?via=google, sign in with Google (email and GitHub work too), and a personal account is ready for me. 2) Free minute: on the page where I approve the connection (or at https://opencalls.dev/app/start) I give my mobile number and you call me at once for a one-minute introduction, free and without a card; that number becomes my callback number. Calling anyone else needs credit I add myself in https://opencalls.dev/app/billing. 3) Connect: help me add Open Calls to ChatGPT. MCP server URL: https://opencalls.dev/mcp. Authentication: OAuth (I sign in on opencalls.dev and approve access to my account). Your own documentation: https://help.openai.com/en/articles/12584461-developer-mode-apps-and-full-mcp-connectors-in-chatgpt-beta. Walk me through Settings › Apps & Connectors › Developer mode › Create step by step if you cannot add it yourself. When a call may need my answer, choose “Always allow” for respond_to_call so answers reach the person on the phone in time. 4) Confirm: run get_workspace and tell me that my account is connected, my available credit, the destination rates and its next_step. 5) First test call: I will give you my own mobile number. Quote the maximum charge for a one-minute call from the destination rates in get_workspace, ask for my approval, then use call_business in ask mode to call me and ask one simple question, for example what I would like for lunch tomorrow. Poll get_call until it ends and tell me exactly what I answered, with the supporting quote. After that we can try a real business. Getting-started guide: https://opencalls.dev/start Never place a call, spend credit or change settings without asking me first; every call needs my explicit approval and a maximum charge.
You need a ChatGPT plan with Developer mode connectors (Apps & Connectors). Open Calls itself has no subscription; calls use prepaid credit.
Pay as you go at $0.25 per minute of AI conversation, billed by the second after a one-minute minimum, with a cheaper waiting rate while the line keeps the AI on hold. Your assistant quotes the maximum before every call and you approve it.
No. Every call needs your explicit approval and a maximum charge, calls are information-only, and you can stop a call at any time.
Yes. Sign in with Google, give your mobile number, and your AI calls you for a free minute to introduce itself, with no card. After that, add credit to call anyone.
