Development of Internet network allows voice communication by Voice over Internet Protocol (VOIP). Session Initiation Protocol (SIP) is the most important signaling protocols in this network. This paper related to Denial of Service (DOS) attacks; specifically INVITE flooding attacks on SIP protocol. In this kind of attacks, an attacker disrupts Server network service by sending successive invite packets. In this paper, we explored modes of emergence INVITE flooding attack and the effects of this attack on SIP server. Results of this experiment indicate that after increasing attack rate, server CPU usage consumption surges. In addition, high CPU utilization leads to rise in the number of transmitted duplicate packets and reduced successful session. Moreover, we demonstrated that faster attack detection can be obtained by replacing Jeffrey distance instead of Hellinger distance.
