Abstract: A method of detecting misrouted inter-office transport facility routes in a telecommunications system is disclosed. The method includes receiving a plurality of provisioning orders corresponding to a plurality of newly requested inter-office facility routes to be added to the telecommunications system, and comparing the plurality of newly requested inter-office facility routes to a plurality of preferred routes that have been stored in a preferred routes database to identify a first set of routes that match the preferred routes, a second set of misrouted routes where a preferred route has been defined and previously stored, but where the newly requested route does not match the preferred route, and a third set of unmatched routes where a preferred route has not been previously stored in the preferred routes database.
