Hi, I'm making a simple user agent using PJSIP. I'd like it to use TCP as transport. For the first version, I'm sending an INVITE SIP message with a text/plain body content. Just after sending this message my program exits. When I use UDP as transport it is working great. I can see the body content using tshark/wireshark. When I use TCP as transport, my client is sending a reset(RST) TCP after getting the ACK and it is not working. Please see this capture : ua -> server TCP 41474 > sip [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=473034042 TSER=0 WS=6 server -> ua TCP sip > 41474 [SYN, ACK] Seq=0 Ack=1 Win=5792 Len=0 MSS=1460 TSV=103628850 TSER=473034042 WS=7 ua -> server TCP 41474 > sip [RST] Seq=1 Win=0 Len=0 Does anyone know why? Appreciate your help. Luis -------------- next part -------------- An HTML attachment was scrubbed...
