I know that there's only little confidential information but it's my boss who told me he didn't want to, he knows better than me the agreements made with the operators so there might be something telling that we have to keep the captures inside the society. I'll ask him again to be sure.

I tried to isolate the packet on which it crashed and it hasn't crashed. With the capture file which hasn't the packet on which it crashed, it crashed at the same number of packet as before (956).

And what is a "backtrace of the stack"?

Thx
Joseph

Well, there's little confidential information in H.248 as far as no
BICC/SIP/H323 traffic is seen there's no way to trace back a call to a
specific user just from Megaco. I been a troubleshooter on "split"
telephony systems for quite few years already and one of the hardest
things you have to deal while troubleshooting MGws is that there's no
way to know which call belongs to which user without interrogating the
MGC.

You could filter h248 away from the capture and see if that crashes.

However you can do few things:

You can give me a backtrace of the stack at the moment it crashes. (To
know where it crashes can *really* help).

try to get tshark to crash, isolate the one packet on which the crash
occurred and see if it crashes "by itself".

I get an error in a window which tells me that TShark has encountered a problem and must shut down. If I launch the debug program, I get in Visual C++ and I get the message: unhandled exception.
