PURPOSE:To attain plural paging calls and responses by one device at the same time by providing a temporary storage circuit storing extension numbers of plural callers and individual numbers of called parties corresponding to the extension numbers to a voice paging device. CONSTITUTION:When an extension telephone set TEL-1 dials a specific number of paging call, a central controller connects the TEL-1 to a paging device PGU so as to attain paging call. When an individual number of the called party is dialed from the TEL-1, the PGU stores temporarily the extension number and the called party number of the TEL-1 so as to await the response of the called party. Thus, the PGU stores temporarily the called party number corresponding to the plural extension numbers. When the called party dials a specific number and dials the individual number of the called party itself, the PGU selects a corresponding number out of some individual numbers so as to connect it to the corresponding extension number and eliminate the number stored temporarily. |
