Hang up. Didn't answer and blocked

I have been getting these calls daily--never answer as I know no one in New York and the number has no meaning.  After a long time, the creative idea of how to reciprocate to these unwanted solicitors was passed on by a friend who practices it relentlessly.
He uses an electronic tone generator and runs it through a pair of good speakers at 300 decibels or so using high Hertz values directly into the phone whenever he gets unwanted repetitive calls.  Don't know if it works in getting off the lists quickly, but I am going to try that too and see what happens.

These people used to call every day last year after I canceled verizon. It stopped about 6 months ago and now has started up daily again. They do not take a hint!!! Even if I ever thought about going to FIOS, these antics would make me think twice. Need to block them.
