Do Not Disturb (DND) allows IP phones to ignore incoming calls. DND feature can be
configured on a phone or a per-line basis depending on the DND mode. Two DND
modes:

Phone (default): DND feature is effective for the IP phone.

Custom: DND feature can be configured for each or all accounts.
A user can activate or deactivate DND using the DND key or DND soft key (not
applicable to SIP-T20P IP phones). The server-side DND feature disables the local DND
and call forward settings. If the server-side DND feature is enabled on any of the
phone’s registrations, the other registrations are not affected. For more information on
call forward, refer to
Call Forward on page 110 .
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.
