VoIP - IP Telephony White Papers
Detecting Spam in VoIP Networks
Overview Voice over IP (VoIP) is a key enabling technology for the migration of circuit-switched PSTN architectures to packet-based networks. The problem of spam in VoIP networks has to be solved in real time compared to e-mail systems. Many of the techniques devised for e-mail spam detection rely upon content analysis and in the case of VoIP it is too late to analyze the media after picking up the receiver. From the observation, when it comes to receiving or rejecting a voice call people use social meaning of trust and reputation of the calling party. This paper describes a multi-stage spam filter based on trust, and reputation for detecting the spam.
