Well perhaps the generated traces can be used to initially check the dissector implementation and you can use your private traces to check the result? Given a trace with a CDR and a interpretation of the CDR in the trace I could try to take a look at the asn1 part if time permits. The asn1 code from 3GPP TS 32.298 should be used right?

I'm using gtpp as name e.g. packet-gtpp.c so probably gtppcdr. > Do you have any example traces to share? > > I'm limited in my ability to share traces that I get from others because they contain information from their network (phone numbers, IMSIs, etc). I can generate them myself using open-cgf and it's test tool but this isn't yet a good basis to build another implementation of (sort of like building a house using a square you built yourself). I'll think about the possibilities, I would like to get a trace up onto the wiki.
