SIP phone system: every room becomes an extension.
Every Audio Deck registers as an extension on your phone system, for example a Fritz!Box¹ or Asterisk. You make hands-free calls through the built-in microphones and see who is calling. Separate desk phones are not needed.

Take calls wherever you are
- Hands-freeThrough the built-in microphones, with echo cancellation. Your hands stay free.
- Callers by nameThe address book is synchronised via CardDAV, for example with our Radicale hosting. You choose the sync interval. Incoming calls show the name instead of the number.
- Registration at a glanceA green “OK” in the web interface shows that the extension is registered. If the registration drops, the device registers again automatically. Raw output is available for troubleshooting.
- With your mobileVia Bluetooth² (HFP) you take mobile phone calls on the room speaker. More on Bluetooth
- With the smart homeVia Home Assistant³ the music is muted when a call comes in. More on the integration
