PURPOSE: A sip service system and a control method thereof are provided to enable normal call processing regardless of network environment such as a public network and a private network using different IP address. CONSTITUTION: Terminals(10,20) transmit registration request message establishing terminal binding information including a destination address. A message convert server(100) creates the unique key of a terminal by receiving the registration request message. The message convert server transmits the SIP message to the destination address of the terminal using the terminal binding information corresponding to the unique key. A call session control device(200) registers the unique key and server binding information by receiving the changed registration request message from the message convert server. The call session control device transmits the server binding information to the message convert server according to the server binding information. |
