Skype is software that lets you make and receive free phone calls with excellent sound quality. This is possible because Skype routes phone calls through the Internet instead of traditional phone lines. To make and receive these calls, both parties need to download software, available for free on the Skype website. Once both parties have installed this software, they talk to each other through headsets attached to their computers. Their computers must be running the Skype software and connected to the Internet for the entire phone call. You can visit www.skype.com for more information about how Skype works.
The Actiontec Internet Phone Wizard takes this idea a step further and allows you to make Internet calls with your normal phone instead of a headset.
