<DIV><FONT face=Arial>Francois,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>The bi-directional TCP support was added during the
last Geneva meeting. No issues were raised in Osaka. If there are
issues with it, hopefully people will find them before November!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>We could specify that H.323 use H.245v7-- I do not see any
reason why we should not consider that option. The only reason that I did
not increase the revision number is that Annex D may be implemented
optionally. If somebody chooses to implement H.323v4 without Annex D
support, there is nothing they would need from H.245v7.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>However, it really makes no difference at all to me.
I'll be agreeable with whatever the experts believes makes the most
sense.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>I'll correct the Annex D field reference-- it's a shame I
didn't see that before. Thanks for pointing it out.</FONT></DIV>

<DIV><SPAN class=080233618-19072000><FONT size=2>How do we fix this? I think
it is too late to fix H.245v6 isn't it? The alternatives would
be:</FONT></SPAN></DIV>
<UL>
<LI><SPAN class=080233618-19072000><FONT size=2>Require H.245v7 for H.323v4,
instead fo H.245v6</FONT></SPAN>
<LI><SPAN class=080233618-19072000><FONT size=2>Pull out Annex D of H.323
and make it require a different version of H.245. (Extremely bad idea since
the Annex has a lot of other useful material)</FONT></SPAN>
<LI><SPAN class=080233618-19072000><FONT size=2>Pull out the bidirectional
TCP thing we added on-the-spot at the last meeting. At least until the next
revision.</FONT></SPAN></LI></UL>

something?</FONT></SPAN></DIV>

<DIV><SPAN class=080233618-19072000><FONT size=2>Also, there is a reference to
something called <STRONG>t38Capability</STRONG> in Annex D: it should be
<STRONG>t38Fax</STRONG>. (This is editorial).</FONT></SPAN></DIV>
