If a DID is dialed that is not assigned to a ser subscriber our sip
proxy routes the caller to the PSTN gateway.
But the PSTN gateway provider sees the DID as belonging to our sip
proxy so they route it right back to us. And we get in a loop.

So basically it's not your fault but the PSTN gateways fault, it should only
send the assigned DID's to you? You are stating that the gateway sees the
number as assigned to your proxy while you don't.
(you could also check if the incoming message is coming from an ip address
of your pstn gateway)
