Abstract

A system and method for detecting and preventing PSTN fraud and abuse in real time includes a detection engine and a call management engine. The system includes at least one user record, at least one call data record, at least one fraud score record, and at least one remediation record. A call management engine enables users to establish VoIP calls connections to destination phone numbers. A fraud detection engine screens VoIP call connections to detect potential fraud and generates fraud records and remediation records when potential fraud is detected. The fraud detection engine may additionally direct the call management to terminate a VoIP call connection.
