magicJack

Magicjack is a device that plugs into a USB port on the user's computer (or in the case of magicJack Plus, plugs directly into a router) and has a standard RJ-11 phone jack into which any standard phone can be plugged. This allows the user to make unlimited phone calls to the U.S. and Canada. It is a computer peripheral that, in combination with telephony service from the related YMAX Corporation, provides Internet-based telephone service (VoIP) to the United States and Canada. In 2011 the company introduced magicJack Plus, which no longer requires a computer (but still requires the user to have an Internet service provider).
