Well yeah, people need to take responsibility, but IMO we as engineers need
to discuss the specific circumstances and methodologies that enable that to
happen. It's easy to say "they should fix it", and you're not wrong that
they should, but how? Do you have a validation framework in mind which
carriers can implement that prevents fraudulent caller ID information from
being sent without preventing legitimate use cases?

What if you use different carriers for termination and origination?
How does your termination carrier validate that your origination
carrier has allocated certain numbers to you and that you're
therefore allowed to make outbound calls with a caller ID set to
those numbers? That doesn't sound to me like something that can be
solved as quickly and easily as you imply.

It does not really matter.  What matters is that they bear responsibility
for an act in furtherance of a conspiracy to commit fraud.

      The problem is that CallerID is not really the CallerID.  It is
some fraudulent shit created by the caller.  This is not how
"CallerID" was originally sold.  It was sold as being the ID of the
Caller.  If it is not the ID of the Caller then Fraud is being
committed and the bastards should be castrated (or worse), and the
CEO and Directors of the carrier responsible for fraud getting
through to the end-user should face the same penalty.

      See then how quickly this gets fixed.  You will fall off your
chair and it will be a "solved problem" before your arse hits the
ground!
