Need a Voice Chat Program

Can you guys help a brotha out?

I need a decent Voice chat program, doesn't have to be complex, but it'll have to be able to work behind a university firewall.

I can get paltalk to work, but paltalk is so loaded with bloatware and spyware that I'd rather go without.

I use Roger Wilco alot, but I don't know if you could get it past a firewall.
