This number has called me every day for the past week right about dinner time.  The caller gave her name, but would not state her business. Using her name I said, "There is no such person here!" and hung up.

Got this same number that called at 6:25 PDT.  No message

Everyday we're called and everyday they say nothing and hang up.

We've received almost daily calls, usually in the mornings, from 503-928-6030.  The caller usually says nothing, but one time a young male asked for "Amy".  Upon being told there is no one here by that name, he hung up.  The line is continuously busy and cannot be called back.
