One TCP port and 4 UDP ports for audio and video.
Using another standard protocol like SIP wouldn't help much as the
problem is the same (not precisely with firewalls, but with NAT) as it
is also using RTP as transport.

That's implemented in GnomeMeeting CVS.
If one peer has a public IP address, OR is behind NAT but is using one
of the technics mentionned in the FAQ (STUN/IP TRANSLATION/GATEKEEPER
PROXY/...), and if the other peer is behind NAT but unconfigured, then
the call will be established.

The problem is when both peers are behind NAT. If you have time to
invest in this and work on "remote NAT port guessing", then it is
welcome.
