CallAgent
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

01

No call without a plan

Preparing and starting are separate steps. The protocol enforces this, so it applies to every client.

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

The Dial team

CallAgent is built by Weisswurst Dial UG (haftungsbeschränkt) i.G.. We're a small team in Germany that builds tools for AI agents.
