Old fashioned ....CALL THE  NUMBER AND ASK WHO IT IS!

The number has probably been recycled already.  The best bet is to contact the service provider and set up a new number.

This suggestion won't help you get the number of the person, but it will help stop the situation.\n\nAfter getting one of these prank calls, hang up and dial *57.  This will initiate a Call Trace on the last number that called you.  However, if you get a Call Waiting beep during the call that call is the one that will be traced, not the prank caller.\n\nAfter doing this, call the 800 number for your phone company's Annoyance Call Bureau.  I believe each phone company has their own, and you should be able to find that number on their website  (Search for Call Trace) or by calling Customer Service.\n\nOnce there are enough calls (usually around 3) that are successfully traced to the same number they will open a case and forward the information to Law Enforcement for proper handling.

Call the police on the person who called. There are some people with caller ID. Or if they don't they can dial *69 to figure out who called last
