Hi Scott:
I prepared 3 computers to test my demo p2p sip call.
PC_A is registered as user1. PC_B is registered as user2. PC_C is sip proxy server. My expectation testing flow:
----------------------------- 1.I registered the user1 and user2 on the PC_C. 2.PC_A calls PC_B. 3.PC_A will send a sip invite msg to PC_C. 4.PC_C will send back the 100 to PC_A. 5.PC_C will transfer the sip invite msg to PC_B. 6.PC_B received the sip invite msg and send back the 180 and 200 msg. 7.PC_A received the 180 and 200 msg and then created the connection with PC_B. Now, I tried the testing flow use the UDP protocol. It's OK.
But when I tried with TCP protocol, the flow is failed.
The PC_C can not transfer the sip invite message sent from
PC_A to PC_B.
I don't know what the problem is ?? Is any bugs with TCP ?? Ryan Qin
