Over the last years Voice-over-IP (VoIP) is getting widespread adop- tion from business and residential customers.The preference towards VoIP ser- vices stems from the fact that VoIP provides many ways to communicate, with a lower cost than traditional telephony. However, VoIP in its present form may allow malicious users to exploit a number of vulnerabilities, make bulk unsoli- cited telephony calls and send bulk unsolicited instant messages. This exploita- tion is referred to as Spam over Internet Telephony (SPIT). In this paper we introduce an antiSPIT management architecture, by using ontologies, which al- low domain administrators to detect and handle SPIT automatically, based on predefined requirements and preferences.
