A registry wouldn't do any good unless each call is backed by cryptographic proof that you own the caller ID, and every telco provider verifying this proof and rejecting any call that has fake/invalid CID.

The ability to sue is the point, companies won't respect anything less. The telco already has proof of the caller in their call records, and consequently the party with financial responsibility, but that information is not normally available without a subpoena or FBI badge. This would be an enforcement of a chain of ownership of the call, and someone who receives a call will (should) always be able to find the responsible party for DNC violations and more. Oh, but what if the bad caller is just a person who signed up for Mechanical Turk or whatever, an independent representative? They can provide proof that they were hired and pass the responsibility up the chain to BobJonesHawaiianVacations LLC.

  Well the telco doesn't exactly know who is the caller. They only know through which carrier the call came from - and they in turn charge that carrier per minute of inbound calling. It only allows them to pinpoint it to a specific carrier, however the spam calls often use the same carrier as the legitimate calls, and this is where the trail ends. Having an end-to-end chain of ownership for the call that can be verified cryptographically would help a lot, since even you on the receiving end should be able to verify this provided you have the appropriate software on your phone. Bad callers using Mechanical Turk would be a minor issue - you won't even have to sue, just get in touch with their telco and they'll shut down their access for violation of ToS (in fact a lot of telcos already prohibit using their consumer-grade plans for business usage, even if not spam). Unless you're paying those Mechanical Turk contractors a lot nobody is gonna bother setting up extra lines to make those calls, and nobody is gonna pay them a lot of money because the only way this spam works is because it's dirt cheap to spew out those calls with the current situation.
