The DNC list does not automatically block calls. Instead, it provides a list of "do not call" phone numbers to legitimate telemarketers who pay a fee for the list.
The DNC list exempts political callers, survey organizations, charities and companies with preexisting business relationships, but these organizations might have their own, internal Do Not Call list (ask them).
The DNC list is not effective against criminals, spammers and scammers, because those people do not subscribe to the DNC list, and do not care if you are on or off that list.
Its purpose is to stop calls from legitimate telemarketers, and it does a pretty good job at that.

Received calls from this number. Comes up Mississippi on caller id. Asked to speak with me and then started with a spiel and I told them to stop calling and the man who sounded foreign, said we will call back. I hung up. Any more calls, going to file a complaint with the AG's office, FTC, etc.
There is really no reason to get repeated calls from obnoxious callers.
Simply get a phone number blocking service, app or device.
