IP-PBX Training System

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.
