Caller selective identification for telephone calls

摘要

The advanced intelligent network (GAIN) is used to allow a calling party to specify what caller ID information to send to the called party for display. The telephone system Line Identification Data Base (LIB) contains listings for subscribers that may each include a plurality of assigned telephone numbers and names. On an individual call basis, a calling subscriber can control what information is to be extracted from LIB for identification to the called party. Various identification options may be pre-established, the caller invoking a selected option by dialing a corresponding access code with the dialed telephone number.
