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.
