The emergence of the Session Initiation Protocol (SIP) promises simple and efficient handling of multimedia sessions among multiple users. In this work, we present the design and implementation of a VoIP system based on SIP. Our SIP-based VoIP system provides a wide range of services multi-point call, multiple audio encoding formats, and complex functionalities such as call muting and call-hold facilities, and personal mobility support.
