Abstract
A private branch exchange (PBX) system includes plural extension telephones divided into extension groups, and a PBX which sends information about one of the extension group to a caller. Plural extension interfaces (I/Fs) coupling the extension telephones to the PBX are divided into groups. The PBX calls each of the extension telephones coupled to all the extension I/Fs of the extension groups corresponding to a call-in signal. In the PBX, a memory stores text data about the extension groups. A controller sends the text data about the extension group to a caller's telephone responsive to the call-in signal. The information can be thus displayed on an extension telephone or an outside-line telephone of the caller.
