We've scrapped the vent server, and recently set up a mumble server.
The details:
Host: server1.gtfogaming.co.uk
Port: 64738
Username: your forum username
Password: your forum password
Download the client from here: http://sourceforge.net/projects/mumble/ ... e/download
You also probably want to disable the automatic voice broadcast - by default you broadcast when a certain amount of noise is detected. Disable that and use push to talk.
You can also download skins for mumble: some good ones here: http://mumble-tower.de/downloads/mumble-skin - I reccomend this particular set: http://mumble-tower.de/downloads/mumble ... umble-skin
After applying the skin, you should restart mumble for it to apply properly.
We've ditched vent, mainly because it's a nightmare to administrate - random people turning up constantly for their MMORPG scrims etc.
So to get onto mumble, you must be a forum member, simple!
Voice quality seems pretty good (slightly better than Vent I think) - and it has a neat overlay ingame showing who's talking. It also supports positional audio, although I can't seem to tell the difference.
