Do Not Disturb (DND)

DND allows IP phones to ignore incoming calls. Incoming calls received while DND is activated
are logged in the Missed Calls list. 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.

The DND feature is enabled by default, and you have the option of disabling it (not applicable
to CP860 IP phones). Users have no permission to configure DND on the phone if DND feature
is disabled. When DND is enabled, it can be activated locally through the phone or through a
server. A user can activate or deactivate DND using the DND key or DND soft key on the
phone. The server-side DND feature deactivates the local DND and call forward settings. If the
server-side DND feature is activated on any of the IP phone's registrations, the other
registrations are not affected. For more information on call forward, refer to
page 445.
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.
