There are three types of Enhanced Call Forwarding:
Use Enhanced Call Forwarding Unconditional to forward all calls
Use Enhanced Call Forwarding Busy to forward calls when the user’s line is busy
Use Enhanced Call Forwarding No Reply to forward calls when the user does not answer the call
The user can activate or deactivate any of these three types from their telephone, and can specify different destinations for calls that are from internal and external sources. Users receive visual display and audio feedback on whether or not Enhanced Call Forwarding is active.
Display messages on the telephone guide the user through the process of activating and de-activating Enhanced Call Forwarding, and for viewing the status of their forwarding.
Users can choose whether they want, at any one time, Call Forwarding or Enhanced Call Forwarding activated. The regular Call Forwarding feature (called "Classic Call Forwarding" to distinguish it from Enhanced Call Forwarding) continues to be available to users and has not changed.
Each of the three types of Enhanced Call Forwarding can have different destinations based on whether a call is internal or external. Therefore, six different destinations are possible to set up:
Enhanced Call Forwarding Unconditional - internal
Enhanced Call Forwarding Unconditional - external
Enhanced Call Forwarding Busy - internal
Enhanced Call Forwarding Busy - external
Enhanced Call Forwarding No Reply - internal
Enhanced Call Forwarding No Reply - external.
Each of these types of call forwarding can be activated either by feature access codes or by feature button.
When Enhanced Call Forwarding is deactivated, the destination number is kept. When the user activates Enhanced Call Forwarding again, the same destination number can be used without having to type it again.
When Enhanced Call Forwarding is not activated for a call, the call will go to a coverage path, if one has been set up.
