Wireshark-users: Re: [Wireshark-users] Problem Filtering H323 Calls

When you have multiple H.323 calls in a trace it is possible to build a display filter that will cut down the display to just the H.323, H.245, RTP & RTCP packets for one particular call. However, a far easier way is the "VoIP Calls" entry on the Statistics menu.
 
This worked fine up to including Ethereal V0.10.14, but all releases since that up to & including the current version of Wireshark (0.99.2), seem to function incorrectly.
 
With recent changes in 0.99.2pre1, it is better than before, in so much as it does list H323 calls, rather than just the packets. However, comparing it to Ethereal V0.10.14 it does not know any calling or called party numbers, nor does it list all of the calls and does not know the state of a call.
 
I can supply screen shots of the same trace opened in Ethereal & Wireshark as well as an example trace, if someone can look into this for me.

It would appear that the VOIP/H323 experts are out on a call at the moment (and have been for your last 4 repeated messages).  I suggest that you check at the bug tracker, http://bugs.wireshark.org/bugzilla/, for an existing report about the feature, and if you can't find one add it to the list.
 
Either way it will only be fixed when you, or someone else, decides to roll up their sleeves and dig in to the code.
