Use Your Regular Phone for Skype and Landline Calls

The USB-RJ11 Skype Adapter lets you make and receive both Skype and regular landline calls, all from the same phone.

Continue using your phone for landline calls as you normally do. But
when you want to make a Skype call, pick up your phone and press * to
switch to Skype calling mode. Then dial a SkypeOut call to any phone
number, or dial a Skype contact, all from your phone's keypad. Your
phone rings for both landline and Skype calls, just pick up the phone
and start talking!

The USB-RJ11 Adapter transforms your existing phone into a dual-mode Skype
