BIOS Magazine posted a review on the U.S. Robotics USB Telephone Adapter (USR9620)
There are plenty of Skype accessories hitting the market that let you use your home phone for free or dirt-cheap Skype Out phone calls. The USRobotics USB Telephone Adapter (USR9620) is different. It's the only adapter intelligent enough to forward Skype calls to your mobile phone for when you're not near a PC. You can even make Skype calls from your mobile phone to avoid long-distance charges. The device connects to both your PC for Internet calling and a standard telephone line, and there's a call waiting feature for both Skype and standard phone calls.U.S. Robotics USB Telephone Adapter (USR9620) Review
