"We" do, if people would ask properly for it instead of trying instead to break the customer/common carrier contract.
The carriers withhold information from customers that is useful to determine the nature of traffic and whether it should be accepted or rejected. The amount of metadata that accompanies a modern phone call is substantial, and the carrier typically relays only ONE FIELD to the customer.
Customers should demand access to all call/circuit/packet metadata that is necessary or useful to implement their own traffic policy. To the average person, I can see why it might seem that the carriers appear to be ideally suited to police this problem, but the correct way for them to do it without violating their obligations as a common carrier is to empower their customers with the information and the tools to do it on their own.
