Abstract
A device and method of intercepting in-progress calls whose billing numbers have been marked fraudulent subsequent to the initial authorization and validation of the same in-progress calls. The device and method uses criteria to define certain calls as “suspect” and parks all suspect calls after the initial call processing. Because the suspect calls are parked and not released to the general switching elements of the telephone network, the suspect calls can be torn down if the associated billing number is marked fraudulent after call processing. The criteria can maintain a fine granularity by using various Call Park Flags in various databases. In addition, the suspect calls can remain parked for varying amounts of time based on the category and type of call.
