Hey Rahul,</div><div style="font-family:arial,sans-serif;font-size:13px">
<br></div><div style="font-family:arial,sans-serif;font-size:13px">thank you for your pcap file. Your astpp is indeed not succeeding in getting the OK delivered correctly to your pjsua. Also those 400 Bad Session Description are no good. </div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">I do see as well fragmented packets passing by, perhaps an easy test would be to have everything be sent over TCP. Big sip packets tend to suffer over UDP networks. From your sip packets your setup looks quite standard, although with a lot of headers (which is fine), so I'ld give it a try with sending everything over tcp, t_relay_to_tcp should help you out!</div>
