Same routine as listed above. It came in as my home town "Issaquah" and is probably the result of my picking up a call from 206 546 7890 (Seattle) 2 hours earlier. All I do is block calls.
Do not let these creeps into your house. They case the joint and pass information to burglars. Go to an auto supply store and buy an aerosol air horn. Next time they call, blast their ear drums out and hope you gave the creep permanent hearing damage.
