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) will appear
on the LCD screen, and callers will receive a busy message. All calls you receive while
DND is enabled are logged to your missed calls list.
Note
You can enable/disable DND for the phone system, or you can customize DND for each
or all accounts. Two DND modes:
The phone will beep softly every 30 seconds to remind you that you still have a call on
hold.
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.
Do Not Disturb is local to the phone, and may be overridden by the server settings. For
more information, contact your system administrator.
