Uh, PSTN does have this problem too. If you are part of SS7 you can totally
fake call origination information. This has been and still is abused for
criminal-malicous activities and 'billing-optimization'. Remember the lawsuit
of SBC et al against WCOM regarding termination charge misrepresentation?
In the actual PSTN routing of a call the destination information is not
authenticated either. The national regulators run registries where the
carrier-owner of each number block is registered. Very much like in the
RIR system. Depends on country a bit though. In some it's more strict
and in others less.
