"This is not even a valid phone number in the North American Numbering Plan. The NXX prefix must be in the range of 200-999, the NXX may not begin with 0 or 1. A 077 NXX cannot exist in any NPA. My phone system won't even route it because its completely bogus. I just stopped by here to see what was responsible for all of the routing failures I see from this number. Pretty much has to be someone using VoIP service where they are allowed to inject their own CID, and probably from a foreign country where they'd have no idea that 077 is bogus.
Don't bother wasting time and energy reporting this number. It's a bogus phantom that someone just made up. It might as well just say anonymous."

The DNC list does work, but it is only good against law-abiding U.S. based telemarketers.
This is a criminal - so why expect them to obey the law?
Non-profits, polls, political calls, etc are 'exempt'.
