The "Skyjack" plugin converts your ordinary magicJack into a powerful dual mode magicJack Skype calling product. This allows you to place and receive free calls to/from over 500 million registered Skype users worldwide without any time limits or restrictions. The Skype user you are calling or receiving a call from does not need to have a magicJack. You may also use Skype for video conferencing.
If you deposit funds with Skype you may also call regular phone numbers giving you a backup alternative way to call and get through to numbers that may not otherwise be reachable like free conference calling services and blocked area codes. Your caller id can also be made anonymous to the other party.
