Voice over Internet Protocol, commonly known as VoIP, is the routing of voiceconversations over the Internet Protocol (IP)-based network. As the technology is inneed to extend the IP telephony deployments, securing the VoIP infrastructure willbecome increasingly important. This thesis outlines the VOIP technology, the currentVoIP security threats and a brief look is taken at present methods of how to secure theemerging technology where Voice over the Internet Protocol is vulnerable to a numberof attacks.Security is an essential consideration for VoIP providers since eachcomponent in the VoIP infrastructure can be used as a target, and VoIP has specificsecurity challenges as well.Firstly this thesis discusses the VOIP as the new promisingtechnology over the old deployed PSTN. Secondly, addresses the security issues andconcerns of this new technology. Finally, will discuss my proposal of securing the voiceover IP using the blowfish encryption technique at a layer between the SAPI. "Speechapplication programming interface" and the TAPI. "Telephony applicationprogramming interface"on the hardware level compared to other VOIP securityproposals.
