I didn't answer....caller has called before

Keeps calling here, but I won't pick up any number or name I don't know.

Continual evening phone calls prox 7-8 pm and 9:30 pm - one ring and hang-up; wait 10 seconds - another ring and hang-up; when I pick up, I get the "dial tone"; can't get response

They have called several times during the day and after 9 oclock once and i let my answering machine get it and there is never no one there.
