A zone prefix is a dialed prefix that identifies the addresses to be serviced by a given gatekeeper. Zone prefixes are typically area codes and serve the same purpose as the domain names in the H.323-ID address space.
Zone prefixes are set up for the:
Local zone in a managed zone
Remote zone in an unmanaged zone.
