Any benefits over Skype conference calls?

I have a VoIP server set up on NST actually, using the XMPP (Jabber, Google Talk) protocol - haven't touched it in over a year though....
^ yes Ali they use Ventrilo for gaming.

Actually Guru i dont know, ive never used Skype, but Vent isnt hard to use so i like it. and i can setup a free server with a max of 8 Users ^__^
