Voice programs

Here are the three voie programs I've used in the past.

www.teamspeak.com
www.ventrilo.com
www.rogerwilco.gamespy.com

All three of these worked well on a commerical server. with up to 40 people. I ony used Roger Wilco on a home computer, it used a lot of resoures as a server, but allowed us to have up to 5 people talking at the same time. They pretty uch all have the same capabilities, private rooms, password locks, and chat included.
