Abstract

A method and an apparatus used with a private branch exchange for addressee location. An addressee notifies of his or her peresent location by a predetermined dialling operation from an extension telephone, other than an extension telephone allotted to him or her within the private branch exchange system, whereupon a switchboard of the system stores the location of the addressee in association with the extension telephone from which the notification was made. Upon arrival of an incoming call for the extension telephone allotted to the addressee, the switchboard transfers the call to a switchboard operation device which displays the addressee's location. The apparatus further comprises a character display section, the switchboard operation device adatped to operate the switchboard of the PBX system, a memory unit for storing the location name for each extension telephone connected to the switchboard and a profile of each specific addressee, an input unit for entering into the memory unit the location name of each extension telephone and the profile of each addressee, and a switchboard control unit which, upon a predetermined dialling operation by an addressee from an extension telephone other than the one allotted to hime or her, stores the addressee's location at that time point in the memory unit, and if a call arrives for the extension telephone allotted to the addressee under this condition, transfers the call to the switchboard operation unit while at the same time indicating the addressee's present location on the switchboard operation unit.
