the video conversation between a WP8 client and a desktop client is crashing after 32 seconds.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. login to a user in "Boghe" for desktop
2. login to a user in "boghe " for WP8
3. make a video call from desktop to WP8
4. wait for 32 seconds (both screens are active, no time out on WP8)
6. the WP8 client will disconnect. "as terminated". 

What is the expected output? What do you see instead?
the call should last for longer than 32 seconds.

What version of the product are you using? On what operating system?
Desktop V2.0.173.972
WP8 :V2  (downloaded on sep 3)

Please provide any additional information below.

I tested the same connection between two desktop sessions. it lasted for 32 
minutes without a problem

on the log, it starts with this message before everything falls apart . 
#INFO [BogheApp.NativeEventsListner]: *INFO: Stopped [RTP/RTCP Manager] server

Hi, 
 I changed the following line in "TSIP_transac_IST.c" .
if(!self->acked){
        TSK_DEBUG_ERROR("ACK not received");
    ->  //return tsip_transac_deliver(TSIP_TRANSAC(self), tsip_dialog_transport_error, tsk_null);
->it was replaced with ->       return 0;
    }

that's line number 694. the program didn't crash after doing so. but I don't 
know the actual cause of this issue.
