Access Grid can be interoperable with H.323 systems, and over this summer we're
building some pieces to make it simple to connect the systems together. However,
you are correct in identifying the major differences and compatibility issue as
the signalling and negotiation. We will be looking at ways to make H.323
systems able to interface with our Virtual Venues (and at some point also SIP
clients), but at this time it's done by hand by plugging the H.323 endpoint into
an existing AG node.</FONT></SPAN></DIV>

<DIV><SPAN class=928074802-01062003><FONT face=Arial color=#0000ff size=2>There
should be someone on the list who can write up a quick HOWTO on this if there's
not one already at the Access Grid Documentation Project (<A
