Configuring Basic Features
79
Do Not Disturb (DND) allows the IP phone to ignore incoming calls. A user can activate
or deactivate the DND feature using a DND soft key or DND key. DND activated on the IP
phone disables the local call forward settings. The DND configurations on the IP phone
may be overridden by the server settings.
The DND on code or DND off code configured on the IP phone is used to inform the
server of activating or deactivating the DND feature. The DND on code and DND off
code may vary on different servers.
Return Message When DND
This feature defines the return code and the reason of the SIP response message when
the IP phone rejects an incoming call for DND. The caller’s phone LCD screen display the
reason according to the return code received.
