Paul-
The problem is that inclusion of an H.245 message in the tunnel terminates
FastStart according to section 8.2.1 of H.323.  This could be "satisfied"
by using the early H.245 element for the replys so that FastStart could proceed.
At least this mechanism would make it easy to know that the responder (the
called endpoint) was able to overlap FastStart and H.245.
