ABSTRACT:
A call placed by a calling party from within the local office or campus area served by an intelligent PBX of a called party who is a subscriber to a personal reach service is held at that PBX for determination of whether the called party/subscriber is within or outside the local area served by the PBX. This determination is made using two-way paging technology through which a pager-carrying called party/subscriber is determined to be within the local area if the two-way pager carried by the called party/subscriber is registered within the area. If the called party/subscriber is determined to be within the local area, then a local page is broadcast to the called party/subscriber and a return call to the PBX by the called party/subscriber is bridged with the call being held from the calling party at the PBX. If the called party/subscriber is determined to be outside the local area, then the calling party's call is connected over the telephone network to the called party/subscriber's personal reach service network platform. A nationwide page is broadcast and a return call from the called party/subscriber to the network platform is bridged with the calling party's call to complete the connection between the calling and called parties.
