   Are you authenticating INVITEs differently than you are authenticating
registrations?  In other words, are the authentication realm and required
credentials different for your proxy_challenge() than they are for
your www_challenge() for handling REGISTER requests?

   If they are, it seems that all you should have to do is do a lookup() 
and see if it fails.  Presumably, you are doing a save() into your 
registrar/usrloc only on valid REGISTER challenges?


   i.e.

     if(is_method("INVITE")) {
             if(!lookup("location")) {
                   sl_send_reply("403", "Forbidden -- REGISTER invalid.");
                   exit;
             }
     }
