Have been getting these calls on my cell for the past few weeks, don't pick up they never leave a voicemail. Don't know anyone in Washington that would be calling me. Think it may be some automated caller that dials phone numbers incrementally. I get less frequent calls from a similar number 360-322-6086, same area and same time frame of calls. People on that number get either dial tone/hang ups or the cruise solicitor, may be the same people with both numbers.
