If I don't see a known number or known contact when the phone rings, I let it go to VoiceMail. I have an answering message for VoiceMail that contains two things: the tones that signify "this number not in use" and the terse 'leave a message'. The tones kill off the autodiallers that most scam/cold-call diallers use. The 'leave a message' is for the few real people that are on the other end of the line. Anybody who doesn't leave a message will be ignored, and only the (very few) voicemails that I select to answer will be followed through.
