New voice chat program for FREE

So guys I've found this Voice chat thing which I use for my clan on crossfire it's called IMVOX it's really great for small clans because its free and has 30 person slot but you can make your own conference server and make channels and stuff in it well if I helped you find something thank me ummm im not sure if I can post link but I will anyways or you can google it. Voice Chat Alternative - imVOX

I prefer Teamspeak 3 because it is very user friendly and works effectively during games.
