Surely just authenticate all register requests with www-challenge. Hide your gateway and SER behind a firewall so your Gateway cannot be seen from the outside work (from a SIP Signalling perspective), and for PSTN calls from authenticated users do a rewritehost and forward to send the INVITEs on to the PSTN gateway?

perhaps you didn't understand the problem. authenticating register requests is not enough. you also need to check what user puts in contact(s), since you cannot hide your gws from your proxies.
