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).
The magicJack device works exclusively with the company's captive landline supplier and CLEC ( Competitive local exchange carrier), YMAX. Voicemail is stored on the magicJack servers and is delivered via direct telephone access, and email with WAV audio file attachments. Downloadable feature upgrades for the magicJack USB dongle are available from third-party software companies.
MagicJack was an American professional soccer club based in Boca Raton, Florida. The team competed in Women's Professional Soccer (WPS) for one season until legal challenges caused the team's owner to become banned from the WPS, which subsequently folded in 2012.
