Long story short, my friends and I operate a Guild Wars guild named Mercanaries of Xero and we have a 100-slot Ventrilo server. However, as there are only about five people who are regularly on it, I convinced my friend who is the server admin to make a Demigod channel on the server with a bunch of subchannels for individual games further divided into two teams. Best of all, we don't have a password, so, it's open to all. So, if you and some friends want to play some DG with voice chat, well, then, come on in and take your shoes off.
Here's the info:
Hostname: mox.guildvent.net
Port number: 5700
If you find the names of the channels for the individual games to be odd, well, that's because the admin insisted I could only start this up if he got to name the channels. 
EDIT: Forgot to mention that server is situated in San Francisco. So, the closer you are to SF, the better your experience on the server should be.
