I recently had software the supported voice over LAN but cannot find it anymore and can't remember what it was called. Does anybody know of a good application to use for Voice Over LAN?
Easiest option would be teamspeak, install a server on one pc and client on each user pc and connect. http://www.teamspeak.com/?page=downloads You can create diferent channel and event password protect it if you want to keep it private. Oh and works on multiple platforms.
