   My proxy/registrar then forward the SIP message to a PSTN gateway
   and this gateway then makes a dial on the PSTN net.  However, when
   the phone ring in the PSTN net and someone picks up the phone they
   get to see the PRI number for the gateway. It is as if some unit
   along the line here had a logic that goes like this "Hmm.. the
   caller's number is missing, so we insert the PRI number for that
   line.

I suspect the problem is that when the gateway places an outgoing
call, either the gateway or the PSTN switch it is connected to decides
to attach the gateway's PRI number to the call.  You probably need to
configure the gateway to send the correct signaling to the PSTN to
have the PSTN call marked as anonymous.
