Steve, Any customer with a PBX has a valid reason to pass CLI that isn't theirs if they are passing through a call.

If the scam caller is spoofing the numbers then I am not quite sure how T-Mobile can implement the block without blocking the legit owner of the number. The way to correct this as an industry is for them to inspect the caller-id coming in from their customer and if that customer does not own the number or toll free DN they are presenting, the call gets blocked. I know they can do this because our SIP carrier AT&T will not accept outbound calls from us unless we present a number assigned to our account so they can bill back for the call. Truthfully, the carriers do not have a real incentive to stop this because someone is paying to make all of those calls. I don't believe for a minute that they could not stop this immediately. A simple rule that you cannot make a commercial call without presenting a valid callback number would fix this. There is also the FTC problem. They do almost nothing to stop the violations of the Do Not Call list and you get nothing out of reporting the violations. If the enforcement was anywhere near the requirements of the DCMA regulations, this would be reduced drastically. First step would be to make the carriers liable for providing service to these scammers, then they might actually care.
