This is totally cool… You can use Skype directly from your existing phone courtesy of this helpful device.
Actiontec is touting something called the Internet Phone Wizard which apparently enables your existing landline to make and receive those free internet phone calls via Skype Technologies. Previously you would have needed two separate phones. The company claims that the device also improves on the somewhat wonky sound quality of internet made calls and that if you have two phones you can make an internet call on one and additional landline call on the other at the same time.
