Forwarding your calls / 73
P0857846 Issue 02 Norstar-PLUS Modular ICS 2.0 System Coordinator Guide
Telephones that have Forward on busy active can still 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 step-by-step instructions, see “Change the Do Not Disturb on
Busy feature” on page 25.
If you use DND on Busy, the line indicator for an external incoming
call still 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 will be 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.
