Tray and availability
Hide the desk to the tray and keep ringing, or switch to Do not disturb when you step away.
Hide to tray, keep ringing
Closing the desk window doesn't quit the app — it hides to the system tray (menu bar on Mac) and stays registered. An incoming call still rings: you get a desktop notification with the caller, and the app asks for your attention in the Dock or taskbar.
Click the tray icon (or the Dock icon on Mac) to bring the window back. To quit completely, use Quit in the tray menu.
Do not disturb
The tray menu has one switch: Available. Untick it and this desk is skipped when calls ring the practice — they go to your colleagues' devices, or to voicemail if nobody else is available. Tick it again to rejoin the ring.
Do not disturb applies to this desk only. Your browser tab, if it is also enabled for calling, keeps its own setting.
