I said this before I'll say it again the quickest way to get a predictive dialer to quit calling your number is not to answer your phone. Yes I'm aware some people can't do that but if you can do that don't answer calls from unknown numbers and they will drop off grammatically.
If it's a legitimate call, they will leave a voicemail. The world is not going to end if they have to wait a minute for you to call them back
That doesn't seem to add up to me. If the call goes to voicemail doesn't that just give them confirmation that yours is an active number?
Using my method over the last couple of years has reduced our spam calls from several per day to no more than a couple a week, and often less than that, because it makes it appear that my number is no longer active.
