Abstract
A system and method for characterizing phone calls in a public switched telephone network (PSTN), in order to identify Data Service Providers (as distinct from conventional telephone users). The system includes monitoring mechanism disposed at a first location (such as a central office or STP) for monitoring call routing messages directed to the first switch. A generating mechanism, responsive to the monitoring mechanism, is configured to generate a call record, which includes a plurality of call defining elements. An updating mechanism is configured to update a plurality of call records stored at a storage location with the call defining elements of the generated call record. Finally, an analyzing mechanism is provided and configured to analyze at least one of the call defining elements of the plurality of call records to identify Data Service Providers. The method includes the steps of monitoring routing messages directed to the first location and generating a call record including a plurality of call defining elements, the call record being identified by a first call defining element. Thereafter, the method updates a plurality of call records, stored at a storage location with t…
