AgentLine is an open-source AI phone agent / voice agent telephony API. It gives coding agents and LLM apps a real US phone number, a voice pipeline (STT + LLM + TTS), and the ability to place outbound calls, answer inbound calls, handle SMS, and walk IVR / DTMF menus — over REST or MCP.
Use it as a self-hosted alternative to stitching Twilio Programmable Voice + Deepgram + a voice LLM yourself, or as an open-source counterpart to hosted voice-agent products (Vapi, Retell, Bland).
Your AI Agent (Claude, Cursor, OpenClaw, Hermes, Codex)
→ AgentLine REST / MCP
→ Real PSTN phone calls, SMS, transcripts
Works with Claude Code, Claude Desktop, Cursor, OpenClaw, Hermes, Codex, and any MCP or HTTP client.

VOICE_RUNTIME picks who holds the conversation. An agent can override it with voice_runtime.
The built-in path is:
Caller audio → Deepgram STT → semantic turn-taking
→ OpenAI-compatible LLM (or live relay context) → Cartesia TTS → caller
Carriers, runtimes, and the registration API are in docs/providers.md. A copy-paste example is in examples/hooks.py.
[DTMF:1] markers into real touch-tone audio for IVR menus.git clone https://github.com/agentlineHQ/AgentLine.git
cd AgentLine

# Fill in your API keys in .env (see Configuration below)
docker-compose up -d
This starts:

cd AgentLine
python -m venv venv

Skip self-hosting — sign up at agentline.cloud and get an API key instantly.
Copy .env.example to .env and fill in your credentials:
LiveKit's in-process audio bridge needs pip install -r requirements-livekit.txt. The default Pipecat bot needs pip install -r requirements-pipecat.txt. SIP mode for LiveKit does not need the LiveKit Python package.
Once running, visit http://localhost:8000/docs for the interactive Swagger UI.
All requests require an API key (al_live_...; legacy sk_live_... keys are still accepted):
curl -H "Authorization: Bearer al_live_YOUR_KEY" \

AgentLine includes a built-in MCP (Model Context Protocol) server, so AI agents like Claude Desktop and Cursor can use telephony tools natively.
Add to your Claude Desktop config:
Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
{
"mcpServers": {
"agentline": {
"command": "npx",
"args": [
"-y", "mcp-remote@latest",
"http://localhost:8000/mcp",
"--header", "Authorization: Bearer al_live_YOUR_KEY"
]
}
}
}

AgentLine ships with a skill file that lets any AI agent gain telephony powers instantly:
https://agentline.cloud/skill.md
How to use:
AGENTLINE_API_KEY environment variableThe skill file is also included in this repo at skills/agentline/SKILL.md.
docker build -t agentline .
docker run -p 8000:8000 --env-file .env agentline
AgentLine runs anywhere that supports Python 3.12+ and Docker: AWS, GCP, Azure, Fly.io, Render, Railway, etc.
The database schema is in schema.sql. It creates tables for:
voice_runtimeMigrations are in the migrations/ directory.
This repository does not bill anyone. You pay the carrier, speech vendor, model host, LiveKit, or Pipecat deployment you configure.
