Abstract—VoIP is a promising technology for voice transmission on IP-based networks and it has many advantages over PSTN. One of the most important threats in these networks is unsolicited bulk calls, known as SPIT (Spam over Internet Telephony). Our purpose in this paper is doing a deep research into this topic and presenting a new anti-SPIT mechanism.
In order to detect SPIT efficiently we need to extract some features which help us in categorizing the incoming calls. In this paper we propose an approach based on extraction of important features that contain all aspects of call, hence it can detect SPIT efficiently in an acceptable time. In this paper, eight features which are directly extracted from the SIP header are applied in the detection process.
The simulation results show that the proposed framework is a comprehensive and efficient solution which provides acceptable true-positive and false-negative values.
Index Terms—PSTN, SPIT, SIP, VoIP, Caller, Callee.
