Yep... they were all online at one time. Looks like the FAQ's are being
updated. Oh, and there is no special port for MJPG. It's just data, sent
over whatever protocol your using. In this case, either CUSM or RTP...
But wait, Paul found the ports! And he found them online too! Yay for
Paul! :)

To this I would add one thing... if you're planning on doing H.323 through
a Firewall, you NEED to be SURE your Firewall supports it. Just opening the
ports is not enough since the H.323 protocol actually negotiates NEW ports
on the fly. There are only a few Firewalls that can handle this, check the
MeetingPoint web pages for which ones we KNOW we work with. (

Best of luck...
