My God, look at how many pages are here. What about the "do not call list?" Is that worth anything these days! I feel like my telephone number is printed in some gas station restroom or something. I am getting so many unknown, unavailable, etc., calls it is ridiculous. I am sick of this. What is the purpose of registering with the "do not call list" if no one pays any attention to it!
6 pages is nothing around here. The DNC will do nothing to protect you from thieves, liars and scammers. That's up to you.
Call blockers can shield you from the barrage and are available in many forms (built into phones, 3rd party boxes, downloadable apps) that range in price from reasonable to free. Look for "First Ring Suppression" or similar so that once a number is blocked your phone remains silent.
