This Recommendation provides the Stage 2 description for the Call Forwarding supplementary services, supported by an ISDN. The Stage 2 descriptions are comprised of the switching functions and the signalling information flows. The Call Forwarding Unconditional supplementary service permits a served user to have the network send to another number all incoming calls for the served user's number (or just those associated with a specified basic service). The served user's originating service is unaffected. If this service is activated, calls are forwarded no matter what the condition of the termination. The Call Forwarding on Busy supplementary service permits a served user to have the network send to another number all incoming calls for the served user's number (or just those associated with a specified basic service) which meet busy at the served user's ISDN number. The served user's originating service is unaffected. The Call Forwarding on No Reply supplementary service permits a served user to have the network send to another number all incoming calls for the serviced user's number (or just those associated with a specified basic service) which meet no reply at the served user's ISDN number. The served user's originating service is unaffected. This Recommendation provides the Stage 2 description for the Call Deflection supplementary service, supported by an ISDN. The Stage 2 descriptions are comprised of the switching functions and the signalling information flows. The Call Deflection supplementary service permits a serviced user to, in real time, request that the network redirects an incoming call addressed to the served user's ISDN number to another number. The served user's originating service is unaffected.
