With the proliferation of the Internet in the past decade, there has been growing interest in the area of transporting voice data over packet networks or Voice over Internet Protocol (VoIP). An integrated infrastructure that supports all forms of communication, including voice and data, will reduce operation and hardware cost as well as optimizing the available bandwidth. Multimedia and multi-service applications, such as video-conferencing, are being developed, to maximize the full potential of VoIP. As IP networks continue to evolve to support real-time data transfer and VoIP matures, the role of the telephone is revolutionized.

An IP Telephone is a device that transports voice in packets over a data network using the Internet Protocol (IP) of the TCP/IP protocol suite. The theme of the thesis is to understand and develop of an IP telephone system. A pair of prototype IP telephones has been developed. A Server program and a set of protocols have been designed to provide administrative support and facilitate communication for the system.

This project was divided into three sections, namely the telephone hardware, telephone firmware and the server program. The server program is designed to run on a workstation or server on the network. Its main function is to maintain a database of IP telephones (clients), to provide the necessary services to its clients. These services include client registration, telephone number to IP address translation.
