I receive calls from this number and from numbers in the Oregon/Washington region every couple of days. They never leave a message. The national do not call registry is useless. You never hear of these outbound call centers being shut down.
They called and did not leave a msg. From googling it looks like one of those bogus political survey/"free" cruise scams... do not bother to pick up your phones for this one. Besides in a few weeks they will change their number and call you again. Do not call list is useless.
