Chris,
I thought I was being clear enough, so let me try again. 6.2.8/H.323 states that an enpoint must open one (and exactly one) H.245 control channel. When Fast Connect is being used, I assume that the intention is that no such control channel is opened.
To be compliant with 6.2.8/H,323 I would have to open a H.245 control channel irrespective of which type of H.245 procedures I will be using. So if I intend to use Fast Start (and assuming that the other party also supports this), I still have to open a H.245 control channel.

Frank,
Why do you consider this text to be "conflicting"? Specifically, with what does it conflict?
Regards, Chris
6.2.8/H.323 states: "The endpoint shall establish exactly one H.245 Control Channel for each call that the endpoint is participating in." 8.1.7/H.323 never states that when Fast Connect is being used such a control channel should be established. As far as I understand the mechanism this is only required to switch to "normal" H.245 procedures.
It would seem that section 6.2.8 should be rephrased to make clear that the H.245 control channel shall only be established when "normal" H.245 procedures are being followed and not in the fast connect case.
