Skype is free and simple software that will enable you to make free calls anywhere in the world in minutes. Skype, created by the people who brought you KaZaA uses innovative P2P (peer-to-peer) technology to connect you with other Skype users. If you are tired of paying outrageous fees for telephony, Skype is for you!
It's a kickass P2P program, AND it allows group conversations. If you have a microphone, you should definitely download this program. I had a conversation with a 56k user overseas, and the quality beat ordinary telephones by far. And no, it doesn't contain spyware.
Go download it already and try it out. My user name on there is Zelaron if you need anyone to try it out with.

I dont beleive it is illegal. No copyrighted matierals are being distributed without compensation, ive been using it for quite a while and nothing has happened to me. The updated version allows conferance calls as well!!! Much better then teamspeak, on the fact that its crystal clear, almost exactly like a phone.
Telephoning over the interent is not illegal. it's been around for quite awhile but it seems it's getting more stable lately according to Chrusers description. Now all I need is a microphone heh.
