Give your AI agent a phone. call4me handles outbound business calls and inbound calls with your standing instructions, then returns the result and transcript. Connect through MCP or REST, with prepaid credits or x402 wallet payments.
Hey Product Hunt! Since our October 8 launch, we've refreshed call4me's design and our user base has tripled.
The bigger change is what you can build with it. Inbound calls now support saved standing answering instructions, so your call4me number can handle incoming calls and permitted keypad choices. Developers can integrate directly through the new REST API alongside MCP, and agents can fund and place calls through x402. We've also improved Spanish phone menus, long holds and transfers, and added Vesper and Willow voices.
It still works with Claude, ChatGPT, Codex, Cursor and other MCP clients to handle calls to businesses and return the result and transcript.

What would you want your assistant to make or answer a call about?
how long does it sit on hold before it gives up and takes a callback instead?
Keep standing instructions locked to one goal per call. If you let an agent handle open-ended conversations over the phone, transcripts get bloated and parsing fails downstream.
If someone calls and requests something that is not in my saved instructions, can the agent take a message and I can look at it later? I’d want it not to agree to anything on my behalf.
