Do Not Disturb (DND)
You can use DND to reject incoming calls automatically on the phone. The prompt message "n
New Missed Call(s)" ("n" indicates the number of missed calls, e.g., 1 New Missed Call(s)) will
appear on the LCD screen, and callers will receive a busy message. All calls you receive while
DND is activated are logged to your missed calls list.
Note
When DND feature is activated, the IP phone supports displaying a large DND icon on the idle
screen. For more information, contact your system administrator.
You can activate/deactivate DND for the phone system, or you can customize DND for each or
all accounts.
There are two DND modes:
 Phone (default): DND is effective for the phone system.
 Custom: DND can be configured for each or all accounts.
The prompt message will display only if Missed Call Log for the line is enabled. Missed call log is
configurable via web user interface at the path Account->Basic.
You cannot activate or deactivate DND when DND feature is disabled. Contact your system
administrator for more information.
