  • 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.
