MJ Blocking numbers...
MagicJack has started blocking outgoing calls to phone numbers owned by phone companies who charge high connection fees. There is a growing list in the MJ forum here at broadbandreports.com. One example is that you can no longer use MagicJack to call any number in THE ENTIRE STATE of Alaska. Blocked numbers can be identified by three beeps which sound oddly like a busy signal.
Be careful out there...
