Impossible. Consider a country with an open dialing plan. e.g my company has the number +4315056416. Thus, this could be +431505641600000 - +431505641699999 So we have to register 100000 DIDs for a single enterprise number. does not scale > b) The provider could add a custom header containing the AoR for which the > user location was performed.
