I FIRST GOT A CALL AT 11:59 ON 12/21/10.  SINCE I DIDN'T ANSWER, THE PHONE CALL CAME IN AGAIN AND AGAIN UNTIL 1:45AM
HOWEVER, WHEN THEY WOKE ME UP THE FIRST TIME, I SIMPLY TURNED THE RINGER OFF. BUT I CHECKED IN MORNING, AND THEY HAD DIALED MY NUMBER BACK TO BACK CONTINUOUSLY.  THEY WON'T WAKE ME UP AGAIN, BECAUSE I WILL CONTINUE TO TURN THE RINGER OFF AT NIGHT.
