called 3 times in a row.  Didn't leave a message.  I called back right after the 3rd call and after many rings, a message said "this magic jack customer is unavailable to take your call please leave a message."  I told them not to call me again....we'll see what happens.  I don't know anyone that uses Magic Jack or anyone that lives in florida.  Either a wrong number that doesn't believe my answering machine or a scam??
