Abstract
Fraudulent VoIP calls are detected and blocked by automated procedures performed at a router server in the VoIP service provider's system which, usually, just analyzes call requests and sets up a route between the calling and called parties. The stringency of automated fraudulent call detection and blocking processes is based on calling customer credit worthiness and the destination of the call.
