Skype is a little program for making free calls over the internet to anyone else who also has Skype. It's free and easy to download and use, and works with most computers.
Skype (rhymes with stripe) is a proprietary peer-to-peer internet telephony (VoIP) network, founded by Niklas Zennstr�m and Janus Friis, the creators of KaZaA and competing against established open VoIP protocols like SIP or H.323. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. The system has a reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. Skype users can speak to other Skype users for free, call traditional telephone numbers for a fee (SkypeOut), receive calls from traditional phones for a fee (SkypeIn), and receive voicemail messages for a fee.
