I have been getting calls from this number for almost a year and although I do not answer he never leaves a message..  I am on the DO Not Call list but this guy calls anyway.  I did some research of my own, and the caller is real estate salesman Aaron J. Rosen of Keller Williams Realty, Inc of Seattle.  This agent is an aggressive caller who has no regard for the law making telemarketing to folks on the Do Not Call list illegal.
