Audience
AI developers and agent builders seeking to give autonomous software its own phone number for voice calls, messaging, inbound communication, and phone-based workflows
About Dial
Dial is a communication stack for AI agents that gives software its own real phone identity: a number it controls to place and receive voice calls, send and receive SMS, and message over WhatsApp through one REST API, MCP server, CLI, or SDK. It rebuilds a telephone stack originally designed around humans, SIM cards, carrier contracts, handsets, and verification flows so autonomous agents can communicate without dedicated hardware or manual carrier setup. Agents can provision a real phone number, make AI voice calls that follow instructions such as booking, confirming, or following up, and use live transcription with optional transfer to a human. Dial also supports two-way SMS and WhatsApp messaging, inbound calls and texts, AI receptionist behavior, and streamed inbound events. Agents can receive SMS verification codes for phone-gated workflows and react to communication events programmatically.
