Not sure how many of you have heard of or even used the voice over IP software known as Skype. For those that have not, it is amazing. Clear calls to anywhere in the world from PC to PC. And if you are needing to call someone on a standard phone, the rates are very good.

Skype is a user friendly P2P software, that allows you to make free Internet telephone calls (VoIP) to any other Skype user, anywhere in the world. The sound quality is as good or even better than regular phones, and requires no additional equipment, besides a normal PC microphone or headset. The Skype interface is similar to popular instant messenger clients and allows you to create a profile, with optional picture, that will be displayed when you call other Skype users or receive incoming call. The program is very easy to use, and works with firewalls and NAT without any additional configuration changes. Basically, all you have to do is download, select a Skype username and you are ready to make or receive calls.
