Folks, I was asked to clarify the text in section 1.5 so relating to the logical channel numbers of bi-directional channels. I just changed this a few minutes ago.. so it is new :-) Please look at that and all other sections (if you have not yet reviewed the document), as I would like to see all of these corrections inserted into H.323v4 and H.225.0v4 prior to publication, if at all possible. If you have any concerns or objections, please let me know. Thanks, Paul
