Jim – Started a business with the original one in 2009 and used it for my business phone. It worked great and probably saved my company upwards of $1,500. Have upgraded to magicjack plus for my business line and also added one for my home number. My wife uses the phone a lot and has nothing but praise for it (she was very skeptical). You need a high-speed (DSL, Cable) connection as it will not work on a dial-up line. Using it on a dial-up line would be stupid anyway. Isn’t the idea to tell the phone company to take a hike? Only issue is they can only transfer some numbers, not all. Not thrilled about having to change my number with everyone, but for $20 a year, I can deal with it.
