Wireshark-dev: Re: [Wireshark-dev] [Bug 1386] LUA + Megaco/H248

Thanks for your answer.
h248.id contains the termination id (I find it wierd, what is terminationid used for? In wireshark a filter on h248.terminationid works).
But how can I also get the transaction and context ids? They also don't work.

And another question, I can't get the values of the termination ids or the commands in the message, I can print them but nothing else. It is a userdata type and I'd like to cut it in pieces (when there are many ids in one packet) to cast it into number or string. How is it possible?

Thanks.
Joseph

I copy the answer to your mail I gave in the dev-list:

Well, this is an odd one... the way ASN1 elements are added to the
tree is somewhat twisted... I'll be investigating how these are
made...

What you want is "h248.id" that is a byte-string containing the
termination id you are looking for terminationId is something else in
the syntax.

as a rule of thumb test if a filter works before using it in your code...

B.T.W. have you tried H.248's "Keep Persistent Context Information"
Preference... it adds a tree that does context analysis.
