Call forwarding definition
Call forwarding is a traditional communication service in telecom industry, also known as call forwarding and incoming call forwarding. If you can't answer the phone or don't want to answer it, you can transfer the phone to another phone number.
Call forwarding type
Unconditional call forwarding -CFU (Unconditional call forwarding)
Whenever the subscriber has a new call, regardless of the current status of the called subscriber and whether it is turned on or not, the network will automatically transfer the call to the subscriber's preset number, and there will be no ringtone.
Busy Call Transfer -CFB (Busy Call Transfer)
If a new call arrives while the subscriber of the contracted service is talking, the network judges that the subscriber of the contracted service is in a busy state, and will automatically transfer the subsequent new call to the telephone number preset by the subscriber of the contracted service.
Call forwarding without answer -CFNRY (call forwarding without answer)
If the phone of the user who registered the service rings within a certain period of time and no one answers (the answering time is preset, for example, 30 seconds), the network will automatically transfer the call to the preset phone number. Depending on the model of mobile phone, the ringing time is not exactly the same, usually 30-60 seconds.
Unreachable call forwarding
The network doesn't know the user's current location information, for example, the mobile phone is turned off, and the user has reached the blind area covered by the network (not in the effective service area, poor signal). At this time, when he is called, the network cannot page the user, and the network will call the incoming call to the phone number preset by the contracted user.
