Not true. G.723 audio on CU works on point-to-point conferences with no
intervening server.

This is true too.

With MeetingPoint, you can use MS NetMeeting's audio in a true multi-point
environment (though the video is only 1 remote window at a time).

I also agree with Jason's statement about audio -- bandwidth makes the
difference.

In my personal experience, I can get great p-2-p audio on a 28.8 connection
when the Internet Gods are friendly--which ain't on AOL on a Friday night ;-)

When I am on a LAN with a private MPCS server, I can get great audio
conferencing quality (but then again I have the bandwidth).

And yes, G.723 and Digitalk are optimized for voice, I believe.

Other audio issues to tweak -
1) Get a good mic
2) Determine if your sound card requires a powered mic or not. This can be
a showstopper. Some audio God can jump in on this point.
3) Make sure the Windows audio system has the correct input selected and is
pumping out enough volume.
