This is all false. Why do we have this same discussion over and over
again every few months?

Networks should not mark calling party identification received from
customers as "network provided" in the resulting ISUP Initial Address
Message. In cases in which the customer-provided number cannot be
directly verified to be billed to the party originating the call, it
should be *replaced* in the IAM with the Billing Telephone Number for
the originating party, which is a _required_ component of the IAM.

The FCC could require this at the drop of a hat, and it could be
complied with -- imperfectly at first, much better very quickly --
with the flick of a switch.

Network operators should be required to disconnect customers who feed
bogus customer-provided numbers. Certainly any network providing
customer-provided numbers and claiming them to be network-provided
should be disconnected by all of their peers.
