AgentPhone is the telephony infrastructure layer for AI agents. A single REST API provisions real US/Canada phone numbers for agents with voice calling, SMS, MMS, and iMessage built in, plus unified webhooks, automatic conversation threading, real-time call transcription, hosted-LLM or webhook voice modes, and 10DLC/A2P compliance handled for you. Official Python and TypeScript SDKs and a published MCP server let agents buy numbers, place calls, and send messages through natural language. Founded 2026 (Y Combinator), used by teams at Google ADK, Replit, LangChain, Sim AI, and Alchemy.
