> You'll never get them all to stop calling you so it's easier to deal with the one that you know.

Actually there is a way. I've posted this here before, but can't find it now. Basically you call the police and file a report saying you're getting harassing calls. They'll give you a case number and tell you to call your phone company. You then call the phone company and give them the information from the police. They'll give you a phone number. Every time you get a call from the harasser, you call the number they gave you and it makes a note of where the call came from. (It's not clear if they have information that caller ID doesn't - like whether they can track down spoofed calls. I'm not sure.) After 3 or 4 calls, the phone company calls the police and gives them the information about the harasser. The police call the harasser and tell them to stop or there will be consequences. In my experience, the harasser then stops.

I meant "them" as a category (debt collectors) not "them" as a specific company. Your debt is trivially transferable; getting one company to stop is just engaging in a perverse game of whack-a-mole.

Yes and no. CID can be spoofed. But there's another ID (I want to say CNA, but not sure) that cannot.

VOIP is a different matter, but even there they can at least get to the originating provider (though they may not be in the US, and may have varying degrees of cooperation).

Pretty sure you're thinking of ANI.

You're right, ANI.
