The SIP protocol has been showing for the last few years a strong acceptance by the market. Through a large row of services, in particular VoIP calls and Instant Messaging (IM), SIP has become ubiquitous in the public communications as well as the corporated ones. As a new emerging standard, SIP will certainly be the target of Spam attacks which refer to unsolicited VoIP calls and IM messages. Before SIP spam becomes a real threat for the SIP users communities, its detection has to be so far a necessary component of our online security and privacy protection. In this paper, we investigate two complete solutions for detecting SIP spam. The first solution is based on the reputation concept and has origins in social networks. However, the second one reflects the payment at risk idea. For this technique, we propose a lightweight architecture that requires only slight changes in the existing infrastructures.
