Smitline for ChatGPT.
Can ChatGPT make phone calls? Not on its own. With Smitline connected, ChatGPT can make phone calls for you: tell it who to call and what you need, Smitline calls the US or Canadian number in a natural voice, and ChatGPT tells you what was said and agreed. What you need: ChatGPT on the web, on any plan, Free included. On a Business, Enterprise or Edu workspace, an admin has to allow it first.
Calls use prepaid credit, by the second while connected.
Set it up

Good to know: On ChatGPT Business, only admins and owners can add a custom MCP server. On Enterprise and Edu, an admin grants the “Create plugins with MCPs” permission.
