摘要 |
In the case of an outbound international call originating from the U.S., an international communication system at a first switch receives, over a segment of the communication channel, the calling party's automatic number identification (ANI) and the dialed number (DN). The switch then sends a query to a processor having a previously stored customer processing records (CPRs). The database at the processor correlates the call information with the appropriate CPR; a service identity value is then inserted into a field which is unused for domestic calls. Call information including the service identity value is then transmitted to a second switch. When the service identity value indicates a service has been triggered, the transmitted call information is correlated with the appropriate index in a trigger table. The service-related values associated with the matched pseudo-country code are then inserted into the service-specific parameters. Finally, the service-specific values are delivered to the called party in the destination country using the service-specific parameters. A similar process is performed for an inbound international call originating from a foreign country and an international transit call.
