Do Not Disturb
You can use DND to reject incoming calls automatically on the phone. Callers will receive a busy message. You can
receive incoming calls from authorized numbers when DND is enabled.
A user can activate or deactivate DND using the DND key or DND soft key.
The DND on code and DND off code configured on IP phones are used to activate/deactivate the server-side DND
feature. They may vary on different servers.
Return Message When DND
This feature defines the return code and the reason of the SIP response message for the rejected incoming call
when DND is enabled on the IP phone. The caller’s phone LCD screen displays the received return code.
