Just got this number and getting all these calls from different numbers... several 857 calls.  My wife just entered the  number on the Do Not Call list, so hopefully this will help.  She had to get a new number for her new cell phone as she was getting calls for a man... apparently just got back from a mission in Arizona working with the Navajos... according to his mom.  It was apparently a land line as the guy's name was listed on caller IDs.
