Abstract
Voice communication over the Internet has experienced rapid growth in homes and businesses with the development of Voice over Internet Protocol (VoIP). The growth in number of VoIP subscribers is due to VoIP flexibility, Quality of Service and being low in cost. This growth has prompted a major shift from the traditional public switched telephone network (PSTN) which is circuit-switched to a packet-switched VoIP. The Session Initiation Protocol (SIP), protocol used in VoIP, is responsible in creating session between a caller and a callee for bidirectional communication using SIP messages. The VoIP, as with other services on the Internet, also suffers from various security issues and vulnerabilities, arising from new protocols and the existing infrastructure of traditional data network.
