Smitline for Claude.

Can Claude make phone calls? Not on its own. With Smitline connected, Claude 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 Claude tells you what was said and agreed. What you need: Any Claude plan (Free allows one custom connector), on the web or desktop.

Calls use prepaid credit, by the second while connected.

Illustration: setting up Smitline in Claude. Customize → Connectors: + Add → Add custom connector. Then: Paste the link, Sign in now. The result: connected with OAuth. Claude can make phone calls.
