Bob,
My understanding was that everyone agreed to reference the 1993 version. The H.323v3 document that I submitted to the TSB referred to the 1993 version. However, I noticed that during editing, they changed that to 1998 :-) H.225.0v3, however, did reference Q.931 (1998), but I do not believe that an effort was made to align the references into that document. In reality, I believe we have always followed the 1993 version.
I would like to consider your previous suggestion and just incorporate the parts of Q.931 that we need into H.323 and H.225.0 and remove all references. However, that's more than we can do for H.323v4 now. For now, I'd like to leave the references at 1993.
What's your opinion?
Paul

On of the open issues is the correct version of Q.931 should be referenced in H.225.0 and H.323. When v3 was decided, they was updated to reference Q.931(1998) instead of Q.931(1993). This is a discussion of the impact of this change and how to resolve the problems.
- H.225.0 and Q.931 include a semi-infinite number of references to table,
figures and sections of Q.931. V3 still references the 1993 items even though the parent reference is 1998. It is possible to update all the detailed references or to return the parent reference to 1993. Either way they must be consistent.
- Q.931(1998) introduced a number of changes from the 1993 version. If we
update v4 to consistently reference 1998, do we want to automatically include all the changes in Q.931?
- If we do accept, by default, the changes to Q.931, do any of these
changes
conflict with the ASN.1 coding that we use? If so, how is this resolved?
However this problem is resolved, it must be consistent within H.323v4 and H.225.0v4.
