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.
