Which enum database are you talking about? Something like enum.org or is it your own private MySQL database? Also, are you simply using the enum module to resolve this?
yes, you create a new enum domain, e.g., e164shadow.arpa, and put all your numbers there. then before forwarding the call to pstn, you check if you find enum match in e164shadow.arpa. if so, you know it is an unallocated number.
