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.
