I simply use Do Not Disturb, a feature that came on my 5 year old Galaxy
 S10+ phone. If the number is not in my contact list the phone won't ring
 but will send it to Voicemail. I have Voicemail set to beep once so I can
 check it if I'm nearby. Dunno how many new phones still have this feature.
 So important calls like family, doctors, etc. get through but otherwise
 not. To my surprise looking at the missed calls list I've found that only
 around 1 in 10 non-contact (junk) calls leave a Voicemail, and even then I
 can easily dispatch it after listening only a few seconds, so IMO I'm ahead
 in the battle. YMMV...
