As another thought: - Love 'em or hate 'em, the PSTN doesn't have this problem.
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.
