Call routing
190
System functions and features as of R3.0
syd-0367/1.3 – R3.0 – 03.2013
6. 3. 1. 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
user concept", page 368).
6. 3. 2 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 378), there are other configuration possibilities for redirecting an unanswered
call.
6. 3. 2. 1 CDE Alternative Destinations
If at the original destination the call is neither answered nor forwarded within a
configurable period of time, it can be routed to a CDE alternative destination (see
"Alternative Destination if no Answer", page 132).
6. 3. 2. 2 Default forwarding per user
Separate default forwardings can be configured for internal and external calls for
each user for the cases No answer, Busy and Rejected. Possible redirection destina-
tions include internal or external users, PISN users, abbreviated dialling numbers,
user groups, CDE call numbers, etc. This means the default response if unobtaina-
ble can vary according to the call’s origin, e.g. voice mail for internal calls and trans-
fer for external calls.
The table below shows the interaction with other activated functions, configura-
tions and situations when the Default Call Forwarding function is configured:
