摘要：
When a communication route is established between SIP servers #1 and #3, an SIP server #2 performing a relay between the servers #1 and #3 receives an INVITE signal from the SIP server #1, not describing track information about the SIP server #2 in a Via header and a Record-Route header of the INVITE signal, but transferring the signal to the SIP server #3. Thus, after the transferred INVITE signal, the signal transmitted and received by the SIP servers #1 and #3, does not include the track information about the SIP server #2, thereby transmitting the signal without passing through the SIP server #2.
