U.S. files lawsuits over robocall scams

How do you enforce that with how disposable DIDs are?

It is trivially easy to acquire a block of numbers from any number of sources with easily falsifiable information, connect them to a SIP application to robocall/robotext victims using easily falsifiable CID data and disappear just as trivially.

Programmatic voice via SIP trunking only makes this worse-not critiquing services like Twilio, Plivo or Telnyx, just highlighting one of the unfortunate risks the technology available to us enables.

CID enforcement is a grand idea but I have no clue how you'd actually accomplish it.

SHAKEN/STIR

Doesn’t solve the problem entirely, but makes it easier to identify and blacklist robocall operations using heuristics, rate limiting, etc.

Passing regulation requiring audit logs sounds like a good first step.
