Abstract

See full text

A SOAP-SIP adapter 2 establishes a session with the terminals 5b and 5c in accordance with a SIP. At this time, the SOAP-SIP adapter 2 sends an INVITE message including its own IP address and port number to the terminals 5b and 5c. Each terminal 5b, 5c sends a 200 OK including its own IP address and port number to the SOAP-SIP adapter 2. The SOAP-SIP adapter 2 stores correspondingly the IP address and port number of each terminal 5b, 5c in a memory. The SOAP-SIP adapter 2 transfers a media stream received from each terminal 5b, 5c to the destination of the corresponding IP address and port number by referring to the memory. Also, a pseudo RBT is sent to the terminal A5b from establishing the session with the terminal A5b till establishing the session with the terminal B5c to prevent a silent state.
