Installing a Magic Jack on a Windows 7 computer can be done in a few simple steps. First, you will of course need to purchase the device itself and, if you don't have a standard phone, you'll have to purchase that too. You will also need an internet connection from your computer.
After you have everything, connect the phone line from the phone into the Magic Jack. Then connect the Magic Jack into a USB port on your computer. Windows 7 should identify the device immediately and the Magic Jack will start. For first time use, it will begin an update and then install the software on the computer. When installation is finished - and barring no problems - a dialpad will appear on screen. If you choose, you can use the dialpad to make calls or select from contacts.
You can also use your phone to make calls. Receiving calls is also simple - when the phone rings, just answer it as you would a normal phone.
The user interface is a large dialpad, with access to any contacts you would like to add (which can also be imported from Outlook), as well as a quick listing of your favorites. At the bottom left hand side is a shortcut to your Magic Jack account and opens a new webpage when clicked. Just scroll to the bottom and click on the my account link. The My Account page has information about your account, such as phone numbers, international calling, and ordering additional Magic Jacks. This is also the place where, should you need to be away from the phone, you can forward your calls to a cell phone or another number.
