Chain of Call Forwarding on No Reply:
• Internal: CFNRs are not chained together locally (i.e. the call is routed to C but
cannot be routed any further).
• Existing CFU call forwarding chains are interrupted by CFNRs.
• In the PISN: CFNR chains within the PISN are possible if B and C are connected to
different PINXs.
Notes:
– CFNR chains in the PISN result in long ringing times.
– If a forwarding destination is defined under Default CF if no answer in
the user configuration, it is possible to configure whether CFNR or the
default forwarding is to be executed (see also "Default diversions per
user", page 149).
Tip:
CFNR immediate ring can be deactivated individually for PISN users. This
is useful for instance in the case of externally connected Voice Mail sys-
tems.
CFNR to the exchange
With Call Forwarding on No Reply to the public or private network the user remains
activated in his user group.
Incoming calls on the user groups that reach this user are therefore routed to the
CFNR destination (this applies to ordinary user groups, not large user groups, see
"User Group", page 100).
Note:
If in a user group several users have configured CFNR to the exchange, it
may not be possible to set up some of the calls. The number of calls that
can be set up depends on the resources available at the time (free B chan-
nels in the corresponding trunk group).
