5.2.2 Call Forwarding Unconditional if no answer
Besides the CFNR redirecting function controllable by the subscriber and which
forwards the call after a specific number of rings (see "Call Forwarding on No
Reply (CFNR)", page 445), there are other configuration possibilities for redirect-
ing an unanswered call.
5.2.2.1 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 229).
5.2.2.2 Default Call Forwarding per Subscriber
Default response in the case of unanswered calls can be configured for each sub-
scriber for both internal and external calls. With the appropriate configuration a
Call Forwarding Unconditional to a call distribution element is effected after
delays set separately in each case. This means the default response if unobtainable
can vary according to the call's origin, e.g. Voice Mail for internal calls and trans-
fer for external calls. In a PISN the internal response within the network can be
handled in the same way with this function as the response of the local PINX.
The table below shows the interaction with other activated functions, configura-
tions and situations when the Default Call Forwarding function is configured:
