I'm implementing pjsip on windows mobile device. Some of the cellular carriers have routers that changed sip messages, and causing address & port change in the message. In pjsua_acc.c acc_check_nat_address the code handle the case where the server answers back the correct IP:port he is getting. The problem is when registering to the server without stun server or when using TCP connection, the server tries to connect to a wrong port. The log say that the address/port was changed, but there is a check if stun server was declared and UDP transport. I removed this check and it looks that it solves the problem with TCP connection. In UDP with no stun declaration there is still a problem. Am I missing something, or is it ok to do that? Also in sip_transport_tcp.c the lis_create_transport function the local_addr is set to the address found when creating the socket, but the port is random. Is it ok to use the factory port as well?
