he keeps calling and hanging up after about 5 seconds of dead air

apparently old timers hockey claim they are cops, well guess what sorry to say that anyone including the police call my house from a number that says its out of service when I call back will be charged with harassment the next time, stop playing games with people....

bothersome and unwanted

I got the same thing calls and dead air

They just called me, too. No one identifies themselves. Dead air.
