Basically your inbouind and outbound calls should go through the same sequence of checkups, and look for a local user number. Then outbound calls should resort in your PSTN trunk, and inbound calls resort in a 404 Not Found. Also I guess you want to charge your users the same rate regardless if it's on-net or off-net calls, so CDR need to be taken care of too.

well, that was only a hint, but not the whole solution :)

In your case, it would require some database lookup, or maybe the dialplan should go through the customer numbers before sending the call to PSTN. 

enum would be a good option instead of database lookup, as was already proposed on the list.

In any case, this all requires a bit of engineering and design effort.

Looks good but my problem is that I do not have a DID block.  Clients
are porting their numbers so they are all over the place.  My first
three numbers in the system are from three different area codes.  I
would need to include all of my numbers in the expression somehow.  Wit
just three I can use '|' but that won't be practical when I have
hundreds or thousands.
