Criminal Conspirators using this number for some lethiferous purpose.  I called the number back and discovered that not only
did it belong to Magic Jack, but that it wasn't assigned to anyone and is apparently being spoofed by someone/thing.  A creature started talking to my answering machine during it's initial attempt to contact me, thinking it was me for a few moments, that sounded like either a slimy debt collector or sleazy salescreature.  Either one, operating from a spoofed phone number are clearly criminals and anyone who gets a phone call from this number should be aware of their practice. (I am currently debt free so at this point, I am leaning towards the salescreature, however, I have gotten BS debt collector calls before so I can't rule them out.)
