Hi,

I'm not sure who is editor of H.323 Annex D, but...

It seems that there is no reference in Annex D of what version of H.323 and H.245 is required for the procedures to work. There is no way to indicate T.38 or even support of UDP vs. TCP transport in H.245v2.

I think the answer is that H.245v4 or later is required. Perhaps somebody can clarify if this is correct.

In any case, we definitively need to specify in H.323 Annex D which version of H.245 is required...
