IP Telephony Device

Abstract

Voice over IP is being developed to integrate voice and data transmission. Over the past few years it has moved from being a computer toy to a major force in today’s telecommunications systems. It has the potential to provide a wide range of enhanced applications at a lower operational cost with greater flexibility than a tradition phone system. The goals of this project were to understand both VoIP and the existing phone network in order to gain an insight on how the two will be combined. Also to outline the concepts concerned with voice and data networking and the sending of voice over IP. Then to use this knowledge to design and implement a software phone that operates within the Session Initiation Protocol specifications. At the end of this project a program that communicated with other Session Initiation Protocol User Agents and Proxy Servers had been completed.
