The following events can be used as a trigger or condition of the permanently configured call transfers:
- CFU, call-forwarding unconditional
- CFB, call forwarding on busy
- Delayed call forwarding, CFNR (call forwarding no reply); CFNA (call forwarding no answer)
- No call transfer
All types of call forwarding can be used in parallel with your own destination telephone numbers. If multiple call-forwarding conditions are active, the following priority applies:
- CFU
- CFB
- CFNR
If call forwarding on busy is activated and a corresponding destination number has been defined, for example, then the call will be forwarded to this number before using the number set for call forwarding on no reply.
Note: If the incoming call has already been forwarded from another telephone number, then forwarding will not take place again, so as to avoid endless call-forwarding loops.
