  • Subscriber feature services in a telecommunications system
    Patent number: 5790647
    Abstract: Special subscriber features available to a telecommunications subscriber are selected for a particular B-number preassigned to a particular subscriber and stored in a database maintained by a local exchange servicing the subscriber. Whenever an original or incoming call is requested from the local exchange, the involved B-number is compared against the B-number stored in the database. If there is a match, all preassigned subscriber features for that particular B-number are executed prior to the establishment of originating or terminating call connections.
