Just received a call from this number. I didn't answer.

Just received call from 360-461-6321.  No message.
I thought I was on a 'No Call' list but guess it isn't working.
I know no one with this area code.

Weird they called hung up and I got a fast busy tone when I called it back

Noone at the other end. Not craigs list as I saw someone else post. This is a company cell phone I seldom use and its never been used for that. Nobody has this number either.
