# CDR Link

CDR Link is a simple & streamlined helpdesk that lets you tag, assign and respond to your tickets. It is developed by the [Center for Digital Resilience](https://digiresilience.org) and powered by [Zammad](https://zammad.org).

Key differences between CDR Link and a standard Zammad installation:

- In addition to the full Zammad interface, CDR Link also provides a simplified 'shell' interface that focuses on the most-commonly-used functionality.
- Additional channels to communicate with users, including Signal, Whatsapp & Twilio voice messaging.
- More stringent privacy defaults: ticket data is never sent over email and calls to third-party services are restricted.
