 When the server sends a large INVITE request towards the Android client via TCP, PJSIP does not seem to process this request. Looking at the log there seems to be no activity regarding the incoming data. The Wireshark capture at the server shows that server sent the INVITE request as TCP fragments and it does not receive TCP acknowledgement from the client side.

+Smaller SIP requests towards the client work as expected. This issue also does not happen with Android version less than 4.0.3.
+'''Update:'''
+The same problem also occurs in the sending direction. PJSIP sends large (INVITE) request, the log shows it, but nothing actually gets transmitted. After this the TCP socket seems to be disfunctional until it is closed.
