Call Forward And Voice Mail - Nortel ICS 7.1 Coordinator Manual

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 the call may be
routed to the prime set for the target line regardless of the DND
on Busy programming for the telephone.
Tip -
telephone activates this feature, the telephone 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 about Hunt Groups see Programming Hunt Groups
on page 165.

Call Forward and Voice Mail

If you want a voice mail system to pick up unanswered calls
automatically, do either of the following:
• use the internal number of your voice mail as the
destination when you program Forward no Answer and
Forward on busy
Note: If the voice mail hardware is attached to another
system on the private network, the forwarded number for
the voice mail system will be an external number on all
systems in the network, except the one to which the voice
mail system is directly connected.
• make the ring delay greater than the delay used by your
voice mail system, if your voice messaging system or
service automatically retrieves calls
