- Calls can be rerouted to a different user if the originally addressed user fails to answer the call within a certain interval. This operation is called Call Forwarding - No Response (CFNR).
- Calls can be rerouted to a different user if the originally addressed user is currently in a call (for example, the line is busy). This operation is called Call Forwarding - Busy (CFB).
- Calls can be rerouted to a different user unconditionally. This operation is called Call Forwarding - Unconditional (CFU).
