At home we don't answer calls unless we recognize the number.
My cellphone voicemail is a recording of the number is not in service message. That stopped every call I didn't want and some that I do. It also helps that I've had my number since the 90s and they blocked caller ID info from cellphones back then so it still says private number when I make calls.
I never answer if a blocked number, private number whatever shows up. I do have to answer local phone calls because I run a business so sometimes they get me anyhow butt I always block a bad number and won't answer an out of state number unless they leave a message.
