When I use ethereal 0.9.15 to decode H225 mesasges using cisco trunk groups, ethereal reports the packet as a Malformed Packet.

It looks like the group should be decoded as a string, however ethereal is not displaying it as one.

I included a capture file with an ARQ and an LRQ using trunk groups; the trunk group also is sent in the ACF/LCF and the H225 setup.  I also attached a "debug h225 asn1" debug from a cisco gatekeeper which shows the ASN1 decode.

Thanks,

Mike Oliveras
