I'm also on the National DNC list and just got 2 calls from this number in a row, (rang, quickly hung up before I could answer, twice) so I looked it up and this page came up. Looks like whoever they are they're notorious. I've gotten a couple calls from telemarketers since I signed up but it hasn't happened in awhile. From reading others comments, I'm glad I didn't answer or call back!
Number called, but I ignored since I didn't recognize it. Left a message about a chance of a lifetime, and I should call back.
Deleted message. They call almost daily. It is obnoxious.
