AgentPhone

Phone numbers for AI agents

Visit AgentPhone

AgentPhone is a telephony service that gives AI agents their own phone numbers and lets them handle voice calls and text messages through a single unified webhook. Incoming calls are transcribed in real time and delivered to the agent as text; the agent replies with text, and AgentPhone handles speech synthesis. Numbers are US and Canadian local numbers, provisioned through one API call.

Integration options include a Python SDK, Node.js SDK, REST API, and an MCP server, with support for Claude Code, Cursor, OpenClaw, Windsurf, and other MCP clients. Additional channels include iMessage, WhatsApp, RCS, and SIP trunking, along with call recording and conversation threading. The platform is SOC 2 Type 1 compliant, with encryption in transit and at rest, MFA, audit logging, and daily backups.

Pricing is usage-based with no plans, seats, or minimums: numbers are billed monthly per line, voice by the minute (with a lower rate for self-hosted agents and a higher rate for hosted agents), and messaging per segment. New accounts receive starting credit, and call recording is an optional monthly account add-on. Sub-accounts are available for running the service for your own customers.
