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.

It also includes a business dialer built into the CRM for inbound and outbound calls, with automatic call logging, searchable transcripts, CRM sync, and AI-generated call outcomes.
