If you have the route[PSTN] from default config file, then inside it
there are some checks to see if the dialed number is in international
format. You may need to adjust those conditions to fit better your needs.

If the conditions in route[PSTN] are not met, then in some case it
returns, meaning that (based on youre xample snippet above),
route[LOCATION] is executed as well. Overall should be harmless, as
there should be no active record in location table, but if you have
other services like voicemail enabled, it is better to send not found if
not local subscriber and route[PSTN] returns back.

Cheers,
Daniel
