The people behind MagicJack, a plug-and-play VoIP device, have recognized the trend of consumers cutting their traditional landline voice connections like much of the telecom industry and have updated their offering to reflect that. MagicJack's original offering was a USB device that came with a phone jack--plug your regular landline phone into the MagicJack, plug that into your computer USB port and make cheap VoIP calls. At CES, MagicJack revealed its 'femtojack' device featuring a small femtocell (think personal cell phone tower of sorts) that plugs into a users PC and allows users to make VoIP calls over their computer using their cell phones wirelessly. The device apparently uses wireless spectrum to connect the phones to the USB device, but because wireless spectrum is not owned inside people's homes, MagicJack can slip through the legal loophole and use the spectrum.
