Hi,

I found a bug in the new h225 dissector:

As you can observe filtering with  "h225.guid ==
00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00" on the attached
capture, both responses will have a defined all-zeros guid as a hidden
field.

If you do not have the request in the capture file this behaviour does
not appear.

The attached pacth workarrounds this behaviour avoiding to add the
hidden guid on responses when it is all zeros. Anyway I think It would
be much better to have the actual guid of the request instead, which I
believe was the original intention.

Luis
