Forwarding your calls 53
P0908510 Issue 02 Enterprise Edge Feature Programming Telephone Guide
Telephones that have Forward on busy active can receive priority calls. If you are
busy on a target line call, another call to that target line is redirected to the prime
telephone for that target line.
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 more information about
changing Do Not Disturb on Busy using the Unified Manager, see the Enterprise
Edge Programming Operations Guide.
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.
Call Forward and voice mail
If you want a voice mail system to pick up unanswered calls automatically
• use the internal number of your voice mail as the destination when you program
Forward no Answer and Forward on busy
or
• make the ring delay greater than the delay used by your voice mail system, if
your voice messaging system or service automatically retrieves calls
Tip
If the Enterprise Edge set is a member of a Hunt Group, the Call Forward on
busy feature is overridden and the Hunt Group call continues to ring until the
hunt time has expired. For more information on Hunt Groups see
Hunt Groups
on page 83.
Tip
If an Enterprise Edge 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
Hunt Groups on page 83.
