Abstract
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. These customized services include for example, connecting callers from a given country to specialized attendants fluent in caller's native language or mapping the originating country code to the country's name for display to attendants.

A method of identifying in a communications system the country of origin of an international call wherein said method comprises the steps of: receiving over a channel connected to a switch of said communications system a telephone number associated with a subscriber to whom said call is directed; correlating prestored information associated with said channel to one of a plurality of originating country codes; inserting said originating country code in a field which is unused for international calls and which ordinarily contains area code and directory number of a calling party for domestic calls; and delivering said originating country code to said subscriber using said field.
Claim 2
Independent Claim
106 words
A method of identifying in a communications system the country of origin of an international call wherein said method comprises the steps of: receiving over a channel connected to a switch of said communications system a telephone number associated with a subscriber to whom said call is directed; correlating prestored information associated with said channel to one of a plurality of originating country codes; inserting said originating country code in a field which is unused for international calls and which ordinarily contains area code and directory number of a calling party for domestic calls; and delivering said originating country code to said subscriber using said field.

A system of identifying in a communications system the country of origin of an international call wherein said system comprises means for receiving over a channel connected to a switch of said communications system a telephone number associated with a subscriber to whom said call is directed; means for correlating prestored information associated with said channel to one of a plurality of originating country codes; means for inserting said originating country code in a field which is unused for international calls and which ordinarily contains area code and directory number of a calling party for domestic calls; and means for delivering said originating country code to said subscriber using said field.
Claim 9
Independent Claim
111 words
A system of identifying in a communications system the country of origin of an international call wherein said system comprises means for receiving over a channel connected to a switch of said communications system a telephone number associated with a subscriber to whom said call is directed; means for correlating prestored information associated with said channel to one of a plurality of originating country codes; means for inserting said originating country code in a field which is unused for international calls and which ordinarily contains area code and directory number of a calling party for domestic calls; and means for delivering said originating country code to said subscriber using said field.
