ABSTRACT:
A telecommunications method is disclosed for processing calling party information so that an "800" or toll-free telephone number or a value-added service telephone number made up of a special service code followed by 7 digits indicating an ultimate destination for the call can be directly provided by a foreign telecommunication administration and processed by a domestic telecommunication administration without the need for the originating foreign telecommunication administration to pass a country identifier or other carrier specific information as part of the dialed number. Additionally, the method provides for a blocking condition which allows calls from certain foreign locations to the dialed number to be blocked.
