I just received a call from this number and it scared the hell out of me for a moment.  When I picked up the phone, all I heard was a long eerie whisper.  I hung up right away, stared at my phone for a minute and decided to call the a$$hole back.  When I called back, I waited a few seconds, hoping to hear some background noises that would give me a hint about the caller, but nothing.  The weird part is, as soon as I spoke, my voice was echoed back to me, every words, every sounds.   I finally hung up, more frustrated than scared at that point.

If anyone got this kind of call, let us try to find those automated creepy calling systems and put an end to this.
