IP-PBX (Internet Protocol-Private Branch Exchange) is an Internet phone system. In comparison with a traditional PBX network, IP-PBX transmits all calls via data packets over a TCP/IP network. The IP-PBX Training System (DCN-100) is an ideal platform for exploring the functions of the IP-PBX. It utilizes the SIP (Session Initiation Protocol) technology to establish audio and video communication within data network. Along with DCN-100, the open-source software – “Wireshark Network Analyzer”, is used to capture and observe the SIP packets. In recent years, the protocol extensions of the SIP have lead to the continuous expansion of the SIP application scope. As a result, the SIP has emerged to be one of the next-generation key technologies in data networking / telecommunication/communication networking realm.
