For the last several days I'm getting calls from this number and a 1-800 number.  It is the same voice calling asking for different people and wanting to know if I know them.  Never heard of any of them.  I have a day sleeper who works at the Hospital and the calls keep waking her up.  Does anyone know who to report these calls to.  Can it be stopped?  Don't want to take the phone off the hook in case of emergency.
