AgentPhone gives AI agents a dedicated phone number for handling voice calls and text messages through a unified API and webhook. It provisions U.S. and Canadian phone numbers, supports inbound and outbound communication, and uses a consistent event format for calls and messaging.

Voice calls can be transcribed in real time, while agent responses are converted to speech automatically. AgentPhone also supports conversation threading, phone-based verification workflows, and integrations through Python and Node.js SDKs, REST API, or an MCP server. It works with MCP-compatible tools such as Claude Code, Cursor, OpenClaw, and Windsurf, making it suitable for AI receptionists, customer support agents, sales follow-up, on-call workflows, coding agents, and autonomous systems that need to call or send messages.
