The system provides for the registering of the wireless unit with the landline network by the dialing of an administrative number from a landline device and causes the VLR in the landline network to directly communicate with the HLR in the wireless network to keep both the landline and the wireless networks up to date as to the registration status and specific routing for the various subscribers. The system is thereby able to route calls efficiently and to alleviate the tromboning effect that often …
