Abstract

A call processing method is disclosed. A first station initiates a call to a second station. Call information associated with the initiated call is evaluated by comparing the call information with information in a fraud database. Completion of the call is prevented if the evaluation results in a finding of fraud. If the evaluation results in no finding of fraud, the call is completed to the second station via a routing path obtained from a routing database. If the call being completed is deemed to be a call of interest, the routing path obtained from the routing database for completing the call is stored.
