You can activate or deactivate the Do Not Disturb (DND) mode on the phone. If DND mode is enabled, the phone will reject all incoming calls automatically, and the callers will hear a busy signal or a message, depending on how your system administrator set up the configuration server.  

To activate DND mode on the IP video phone:  

1. Press the DND soft key when the phone is idle.  

The icon on the idle screen indicates that the Do Not Disturb mode is enabled.  

The phone will rejects all incoming calls and prompt a message on the LCD screen.
