SIT tine
I put an SIT tone in my home answering machine. The special instruction tone tells the predictive dialers that my line is not in use. The 3 rising tones are the answer then you get my voice saying leave a message. Humans leave one, the others drop off. It took about 4 weeks and we noticed a dramatic drop in calls. I can now sit down to a cocktail uninterrupted.
