DND on Busy
When you are busy on a call and a second call comes in, your
telephone rings softly to alert you to the second call. If you
find this second ring distracting, you can have the system
prevent a second call from disturbing you by assigning Do Not
Disturb (DND) on Busy to your extension.
When DND on Busy is turned on for the set, internal and
private network callers hear a busy tone instead of ringing
when you are on the telephone. External callers are transferred
to the prime set used in your system. For step-by-step
instructions, see
Making Changes to Do Not Disturb on Busy
on page 39.
If you use DND on Busy, the line indicator for an external
incoming call flashes, but your telephone does not ring.
Forward on busy takes priority over DND on Busy.
If an external call uses a target line, the call is processed
according to the programming of the target line. If the target
line is busy, the caller may hear a busy tone or be routed to the
prime set for the target line regardless of the DND on Busy
programming for the telephone.
Tip -
If a set is a member of a Hunt Group and the set activates
this feature, the set does not receive notification of incoming
Hunt Group calls while on a call. The DND on busy feature
overrides the Hunt Group. For more information on Hunt
Groups see Programming Hunt Groups on page 161.
