Call routing
6. 3. 3
Personal call routing
Several terminals can be allocated to an internal user. A call to this user is routed to all
the terminals allocated to him or only to a number of them (see "One number concept
and personal call routing", page 331).
6. 3. 4
Call Forwarding Unconditional if no answer
Besides the CFNR redirecting function controllable by the user and which forwards the
call after a specific number of rings (see "Call Forwarding on No Reply (CFNR)",
page 340), there are other configuration possibilities for redirecting an unanswered
call.
6. 3. 4. 1
CDE Alternative Destinations
If at the original destination the call is neither answered nor forwarded within a config-
urable period of time, it can be routed to a CDE alternative destination (see "Alternative
Destination if no Answer", page 124).
6. 3. 4. 2
Default call forwarding per user

each user for the cases
tions include internal or external users, PISN users, abbreviated dialling numbers, user
groups, CDE call numbers, etc. This means the default response if unobtainable can
vary according to the call's origin, e.g. voice mail for internal calls and transfer for ex-
ternal calls.
The table below shows the interaction with other activated functions, configurations
and situations when the Default Call Forwarding function is configured:

CNFR call forwarding delay is shorter than the internal or
