#1488 closed defect

Problem with sending and receiving large (INVITE) requests over TCP on Android 4.0.2/4.0.3 possibly due to fragmentation — at Version 2

Description (last modified by bennylp)

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 (or error was sent)

This has been tested with different wi-fi routers and 3G providers and the issue remains. Smaller SIP requests towards the client work as expected.

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.
