Definition[edit | edit source]
Call forwarding refers to the ability to redirect a Directory Number (DN) from one destination to another Directory Number. This feature can be activated and deactivated at any time from the subscriber’s telephone set.
Overview[edit | edit source]
Electronic switching systems have the ability to redirect an incoming call to either another Directory Number within the same exchange, or to another exchange over a trunk line. When a call is redirected by the switch, the call content is not transmitted to the subscriber’s line, but instead is rerouted at the switch.
