Today, VoIP is growing to the point where companies of almost any size in any indus experiment roll in the hay how to take advantage of the cost savings and other emerging added features in VoIP. As VOIP is gaining wide adoption and becoming iodine of the mainstream communication technologies, security has become a major issue. Network Administrators are purpose themselves in a tough position of providing their clienteles with the security and reliability that they have grown accustomed to everyplace these years.The threats to security and privacy could be in the form of DOS (denial of service), malformed messages, sniffing, spoofing, vishing, VOIP spam and SPIT (spam everyplace VOIP). The vulnerable components under threat done the use of VoIP could be access device application, management interface, network, tftp server. content t o secure the VOIP network could be VoIP Protocol, Session Border Protocol, or using the network devices.To protect networks from these threats, one of the key aspects is the methodology of securing information that is, to conceal the signals and media in real time communications from unauthorized entities through cryptography.

As internet telephony comes to handle more data, it becomes an easy target for cyber crime. From the beginning of its inception, VOIP infrastructure has ceaselessly been vulnerable to threats from other networked architectures. This happens due to the process of digitization, and encryption of voice, which is then compressed into small packets and sent over the Internet Protocol netwo rk systems. This technicality is presented in the VOIP system which can
