AbstractA communications signal-transmitting device carried by a communications system user indicates the location of that user relative to other wired or wireless communications devices connected to a communications system. This location indication is utilized by the communications system to forward incoming voice and/or data communications for that user to the other communications device so that the user can receive such communications. As a result, the location of any potential system user is provided and call forwarding for that user is accomplished without the prior art problems associated with activation and deactivation. In the disclosed embodiments which pertain to the forwarding of voice communications in a PBX environment, the communications device is a pager which communicates with the wired or wireless telephone sets connected to the line side of the PBX to provide the PBX with the location of the system user relative to these telephone sets.
