Do Not Disturb (DND) Key
The IP phones have a feature you can enable called Do Not Disturb (DND). Configuring a DND key allows you to quickly
turn the DND feature on or off.
f DND is enabled, callers calling into the phone hear a busy signal or a message, depending on how your System Adminis-
trator set up the configuration server. The second line on the screen of the IP phone shows when DND is set.
If the phone shares a line with other phones, only the phone that has DND configured is affected.
For more information about DND and DND modes, see “DND Configuration” on page89.
