I get probably a dozen a day. That "do not call" list is more useless than the "do not fly" and NICS lists. At least it's down some. Before the election I was getting over 20 a day.
I solved my persistent robocall problem with a neat device that really works. It is the Panasonic KX-TGA710B Call Block machine. It sells for about $100 or so. I think it is the best money I have spent on an electronic device in years. I estimate that the incidence of spam calls has declined about 95% since I installed this thing about 18 months ago. Easy to install. Highly recommended.
