I have received 4 or 5 calls to my home phone from this # and 1 on my cell phone.  When I answer I have heard someone talking in the background or they are silent and they just hang up. If I don't pick up, they don't leave a message. When I have tried to call back I always get a recording that says the number is no longer in service.  I found a gentleman who had that number as a fax # until a year ago when he gave it up.We heard on the news people were receiving scam calls  from someone claiming to be with a florida energy program.  Is it possible for someone to enter a fake number as the number calling?
