The magicJack plus is the newest upgrade to the magicJack. The original magicJack brought to us by VocalTec, is a device that allows you to connect your home phone to your computer to be able to make unlimited calls for and works via a VoIP network. The magicJack plus is similar to the magicJack however it has the added benefit that a computer is not needed in order to use the device, rather it can simply be connected via an Ethernet connection. The magicJack Plus has only a minor price increase over the original magic Jack's price. Besides running independent of a computer the magicJack plus also comes with HD Voice and Echo Control which have dramatically increased the sound quality that you get while making calls.
VocalTec has successfully released the magicJack Plus and is currently in the process of releasing the magicJack App which will initially work with the Iphone and eventually on the android platform as well.
