34 Feature Guide
1.3.1.3 Do Not Disturb (DND)
Description
Extension users can use this feature to prevent calls from ringing at their extension. The calling extension
will hear a Do Not Disturb (DND) tone.
Conditions
• DND Override
An extension in DND mode can be called by extensions that are allowed to override DND through
system programming ( DND Override [609]).
• This feature does not apply to calls from Hold Recall, Camp-on Recall, and Timed Reminder.
• Calls from outside (CO) lines programmed as "Normal" or "DIL" ( CO Line Mode—Day/Night/Lunch
[414-416]) can be received at a user's extension, but the telephone will not ring. The corresponding CO
button will flash when an outside (CO) line call is received, and the user can answer the call by pressing
this button.
