The various CFU types are as follows:• CFU to a variable destination:The user specifies the chosen call forwarding destination on his terminal. ThisCFU can be either unconditional or only if busy.• Preconfigured CFU:The call forwarding is made unconditionally to a destination entered in the userconfiguration. This destination is also used with the Leave message feature if thecaller is unable to read messages on his terminal.• CFU if unobtainable:The user configuration can specify where a call should be routed if a terminal isunobtainable. Different destinations can be configured depending on the rea-son for the unavailability and the call’s origin (see "Response if unobtainable",page 200)Note:An existing call forwarding is overwritten by a new call forwarding.CFU Unconditional, CFB and Call Forwarding on No Reply (seepage 378) are equivalent.
