A system and method that controls a wireless call from a home system regardless of its current serving system. In this system, when a wireless telephone is roaming, the serving system sets up a transmission path to the home system. The home system performs all of the origination functions as if the wireless unit were in the local area and communicates via the transmission path, with the wireless unit using the serving system as an extension of the home system.
