I am having problems when using Wireshark with Windows 7.  Whenever I sniff a VOIP G.711A call with Wireshark, the packets are not seen by Wireshark as G.711A but as UDP. Even if I decode the UDP to RTP things are not working properly.

The data side of things ( I can see the packet loss /Jitter etc.)  are working as expected I can however not listen to the call.

I have tried several releases of Wireshark ( last one I used was 1.40 on Windows 7)

When I do the exact same sniff with XP and Wireshark 1.40 – no problem.

Something in Windows 7 is treating the sniffed packets differently. Can you help?


Kind Regards
