A trick I've used to get certain robocalls to stop: once you get someone on the line, especially after they say the call is recorded. Offer them X amount of bitcoin, in escrow, if they callback to your number at later time and share details about who they work for and for access to their systems. Nobody has called my bluff, but usually that call center stops trying that scam to your number. I guess that's enough to trigger a do not call by their supervisors or they don't want to get in trouble by even hearing that opportunity. Unfortunately, I do occasionally get stuck in a system where I get a robocall, but once I get past the sweet robot named Mary asking for final living expense coverages, I now get a 'this number is no longer available' when transferred. After a couple of weeks, I do drop off that list too.
