Overview

About Dial

This summary uses submitted and public product material. Only source-mapped claims are documentation reviewed.

Dial is a communication stack built for AI agents. It gives an agent its own phone number and supports two-way SMS, inbound and outbound voice calls, and account events through a REST API, MCP server, CLI, or Node and Python SDKs.

Pricing is usage-based with a pay-as-you-go option. Current rates are maintained on the Dial pricing page.

So agents can…

Provision and manage a phone number from an agent workflow
Place and receive voice calls and send and receive SMS messages
Wait for inbound events such as replies, call completion, and OTP codes
Use the same communication capabilities through API, MCP, CLI, or SDK interfaces

Listing decision

Why Dial is listed

Dial is built around an agent as the phone identity and first-class caller or message participant, with agent-oriented MCP, CLI, and SDK interfaces.

Before you choose

Fit and limitations

Best for

Agents that need a programmable phone number for two-way SMS, voice calls, inbound events, and phone-based verification workflows.

Known limitations

Free accounts are limited to five minutes per call and two concurrent calls until the first top-up or subscription; write requests are not idempotent, so blind retries can create duplicate messages or calls.
