For those of you that don't watch TV, the magicJack is a USB device that lets you make long distance calls for a flat rate of $20/year. You plug a regular phone into the device. I have run lots of phone and network wires in my house. I didn't see why I couldn't attach a wire to the device, plug into a wall jack, and in the cellar plug that line into a CO port. It works just fine. As long as my computer is running I can initiate and answer calls from any phone in my house. Though I'm keeping my regular lines and won't be receiving calls through it.
