01 — No call without a plan
Preparing and starting are separate steps. The protocol enforces this, so it applies to every client.
About
We give agents a phone line.
CallAgent started as a Mac that dialled out through its owner’s iPhone. Today it runs as a service: Twilio carries the call, a speech-to-speech model handles the conversation, and an MCP server lets your agent control both.
Principles
Four rules we don’t bend
02 — It says what it is
The agent tells people it’s an AI. You can’t switch that off.
03 — No recordings
Audio is never stored. Recording a call without consent is a criminal offence in Germany.
04 — Every call ends
A carrier time limit, an abort tool and a watchdog each make sure of that.
Who we are
