Skype

Skype is the next phenomenon from the people who brought you KaZaA. Just like KaZaA, Skype uses P2P (peer-to-peer) technology to connect you to other users – not to share files this time, but to talk and chat with your friends. The technology is extremely advanced – but super simple to use... You’ll be making free phone calls to your friends in no time!

- Free unlimited worldwide phone calls to anyone else on Skype, anywhere in the world
- Skype video (webcam), see who you are talking to with free video calls
- Chat with up to 100 people in group chats
- Conference call with up to four people for free
- Call ordinary phones with SkypeOut
- Superior sound quality – better than your regular phone
- Your calls are encrypted “end-to-end” for superior privacy
- Friends list shows you when your Skype friends are online and ready to talk or chat
- Works with all firewall, NAT and routers – nothing to configure!
- Super-simple and easy to use
