Pete,
Table 13/H.225.0v3 shows that the User-to-User IE is mandatory. What IEs do you believe are not mandatory?
H.323 states that the fastStart and h245Control components cannot both be present in the Setup message (do I need to quote it again?). A Setup User-to-User IE containing either or neither component is valid; one containing both is clearly invalid. Why do you think otherwise?
H.323, by way of Q.931, requires that the called EP respond with ReleaseComplete with cause 100. There is no other appropriate cause.
The feature that should be deprecated is the inclusion of both fastStart and h245Control in Setup. I was under the impression that either through IGv3 or H.323v4 this had already made it into the standard. If its not too late, we should simply remove this feature from any proposed text; if it is too late, we should deprecate it because it causes insurmountable backward compatibility problems.

Paul,
I don't really believe that the release cause you cite is valid. The IEs are not mandatory, and (taken by themselves) they don't have invalid content. I don't believe it is the intent of this cause code to signal the sort of thing that we are talking about here either.
Are there any other causes and clauses that you think might be more appropriate?
Also, when you say "the feature" should be deprecated, what are you referring to as "the feature"? I'm not quite clear.
Pete.
