  • Patent number: 5506894
    Abstract: A system for delivering originating country information for international calls to a subscriber includes three separate processes. In a first process, the country code is extracted from either billing/routing data forwarded by the caller's national telephone network to the communication switching system of the destination country of the call, or from channel information associated with the call. In the second process, the originating county code is then inserted in either the calling party number or the destination number depending on the subscriber's terminal device egress arrangement. In the third process, the originating country code is delivered to the subscriber before the call is completed. Once received by the subscriber, the originating country information can be used to tailor customized services for the foreign caller.

  • Patent number: 5463685
    Abstract: An outbound call management capability is provided for a public switched telephone network by a network based outbound call management (NOCM) complex, which can be accessed by all subscribers to the public switched network through one or more central offices in the network. A predetermined list of telephone numbers is stored in a data base in the NOCM complex for each subscriber who uses the NOCM services. The telephone numbers are automatically dialed at one or more predetermined scheduled times. When one of the dialed telephones is answered, the NOCM complex sets up a connection through the public switched telephone network between the called party and one or more attendants at one or more telephone numbers specified by a customer of the NOCM services.
