100 percent of all incoming long distance calls to my home phone are telemarketers. And yes, I am on the DoNotCall registry. It doesn't work becasue telemkerters use a different number every time they call. And none of the Verizon call blocking/screening add-ons allow you to block calls from outside your calling area. And even though I can individually block 100 numbers, it takes time and it is not effective. Telemarketers rent banks of phone numbers and cycle through them. I get the same **bleep** calls from different states each time. It would be so much easier to just block all incoming long distance calls. That would cut down incoming phone spam by 95 percent.
