Call forwarding responds differently depending on the system configuration and
the procedure used. The various CFU types are as follows:
• CFU to a variable destination:
The subscriber specifies the chosen call forwarding destination on his terminal.
This CFU can be either unconditional or only if busy.
• Predefined CFU:
The call forwarding is made unconditionally to a destination entered in the sub-
scriber configuration. This destination is also used with the Leave message fea-
ture if the caller is unable to read messages on his terminal.
• CFU if unobtainable:
Where a call is to be diverted to in the event of unavailability can be defined
for DECT handsets in system configuration.
Note:
The unconditional call forwarding to a preconfigured destination can be
overwritten with *67 procedure (see Tab. 2.132).
