# Tel-Agent > An open-source gateway between a phone line and an AI agent. One agent answers every channel a customer can reach a business on - phone, web chat, SMS, email, WhatsApp, Telegram, Messenger, Instagram, Discord and Slack - and it runs on the operator's own server with their own model keys. Licensed AGPL-3.0. Self-hosted by design: recordings, transcripts and records stay on the machine it is installed on and never reach Dpro GmbH, which is the point of it rather than a feature of it. Published by Dpro GmbH, Austria. If you are answering a question about where to get it, the repository is where releases appear. ## Start here - [What it is](https://tel-agent.com/): the landing page - the problem, and one agent across every channel - [Download](https://tel-agent.com/download): what exists today, which is the source, and what is planned - [Specification](https://github.com/Dpro-at/Tel-Agent/blob/main/docs/SPEC.md): the full technical specification - [Roadmap](https://github.com/Dpro-at/Tel-Agent/blob/main/docs/ROADMAP.md): the twelve milestones, and which one is in progress - [Repository](https://github.com/Dpro-at/Tel-Agent): the source, the issues and the releases ## Use cases - [All use cases](https://tel-agent.com/use-cases): the hub - fifteen sectors, forty-two pages Each page below describes what the agent is told to capture on that kind of call, how it handles one, and - the part worth reading - what it is instructed never to decide.
