Caller ID just shows "Everett WA." When you pick up it is just an automated system that verifies a live pick upon your end....Probably so they can spam you more! When you say "Hello" the automated voice says "Goodbye" and disconnects.
It's someone trying to sell insurance and are so rude. When I validated that I was not a person they could do business with i.e. a company who provides my employees with insurance, they hung up on me. I hate that!
