What is AgentLine?
AgentLine is an AI telephony tool that gives your AI agent a real phone number so it can make calls, send SMS, and handle inbound conversations through a single skill. It provisions actual US and Canada phone numbers for agents and handles the telephony layer for you, including outbound calling with bidirectional conversation and inbound call handling for incoming callers. During calls, AgentLine performs real-time audio transcription and delivers it as JSON, plus webhook integration so your application can react to call events programmatically. Integration is deliberately lightweight: it ships as a one-file skill that installs in roughly 30 seconds, and it supports multiple agent platforms including Claude Code, Cursor, Hermes, and OpenClaw. The setup flow is to download the skill, add it to your AI agent, configure an API key, and then enable calling through natural-language prompts. This makes AgentLine aimed at developers who are building voice-enabled AI applications and want to add phone and SMS capabilities without assembling a full telephony stack themselves. Use cases include letting an agent place outbound calls, send and receive text messages, and answer inbound calls as part of an automated workflow. Pricing is not shown on the homepage; the site links to a separate pricing page for details.
