【Example】

Example 1. Embodiment 1 of the present invention will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is a diagram showing the overall configuration of a telephone system according to the present invention. Also, FIG.
FIG. 1 is a diagram showing a configuration of a private branch exchange according to the present invention,
The trunk card 7 to the office data storage device 11 are the same as those of the conventional device described above. Further, FIG. 3 is a diagram showing stored contents of the voice data storage device of FIG. In each figure, the same reference numerals indicate the same or corresponding parts.

In FIG. 1, 6 is an external telephone connected to the public network 1, and 3 A is a private branch exchange having a voice data storage device 12. The extension telephone 5 is the same as the conventional one.

In FIG. 3, the channel number in the first column is the identification number of the line card 8, the extension number in the second column is the extension number possessed by the extension telephone 5, and the extension number is assigned to the voice message in the third column. The name of the user.

In FIG. 1, when the private branch exchange (PBX) 3A connected to the public network 1 by the office line 2 receives an incoming call from the external telephone 6, the telephone 6 selects, for example, "0531232001" as a selection signal. When transmitted, the extension telephone 5a connected to the private branch exchange 3A through the line 4
Plays the voice message "Nagahara-sama call me" assigned to extension number 2001.

The extension telephone 5a has, for example, an extension number 20.
01, 2002, 2003, 2004, and these extension numbers are respectively “Nagahara”, as shown in FIG.
Voice messages of "Yamane", "Mori", and "Nagai" are assigned.

When a call arrives at the extension number 2001,
The central processing unit 10 of the private branch exchange 3A extracts the voice message "Nagahara" corresponding to the extension number 2001 from the voice data storage device 12 and converts it into a voice signal, which is sent to the extension telephone 5a through the line card 8 and the line 4. Sending out and turning on the speaker button of the extension telephone 5a
It also sends out a control signal. And the extension telephone 5a
