Magic-Jack

Using Magic Jack is extremely easy.  You simply plug your existing phone into the MagicJack and plug the Magic Jack into a USB port on a qualified computer* that is connected to the internet.  In just seconds your Magic Jack will provide a dial tone and be ready to call anywhere in the US and Canada absolutely free.  This is the most advanced VOIP (Voice over Internet Protocol) phone system ever, and it's clear as a bell as it uses you existing telephone handset and state of the art software in the MagicJack end.
The first time you plug in your MagicJack, you will be assigned a new free telephone number in the area code of your choice regardless of where you live.  This means you'll now have your own U.S. phone number that allows you to not only make but also receive calls. This breakthrough technology was invented by American entrepreneur Danial M. Borislow, who also founded Tele-Save (Talk America).  Now he's at it again with an idea that has the potential to save telephone users literally billions of dollars.
What really makes the most compelling case for buying a Magic Jack, besides the incredibly low yearly licensing fee, is that you will soon be able to port your existing telephone phone number to your Magic Jack.
