I too just got a call from this number like two minutes ago and they just hung up. I only answered because I know someone in Portland and wasnt sure of their number.
Very annoying - I have a new home number and I get almost 5 calls a day like this (but different numbers) any time I get a person on the other end I advise NOT INTERESTED AND TAKE ME OFF YOUR LIST. They have to honor it within 30 days and it at least slows down these types of calls
