This number called my PRIVATE, UNPUBLISHED home business line TWICE tonight within FOUR minutes of each other at 7PM.  Caller ID said "CALIFORNIA." We did not answer.  Both times, it rang only twice and disconnected with NO MESSAGE.  I currently am running an ad for my business that clearly states ALL callers must LEAVE A MESSAGE with a NAME and  a Call-Back Number in order to get attention.

I suspect this is SPAM, but am surprised to be the first and only one to complain about this number.
