DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a flowchart showing an example of processing by a control section in this embodiment.

In FIG. 1, the key telephone device of this embodiment includes extension key telephones (hereinafter referred to as extension TEL) 102 and 103.
, dial-in line 101 , and outside line speaker 104
The main device 100 is equipped with a main device 100 that accommodates the following.

[0008] The main device 100 includes a dial-in line 1.
The PBX dial-in interface section (hereinafter referred to as PB) detects incoming calls from 01 and designated extension numbers.
X dial-in (INF) 110 and extension TEL 102
. It is configured to include a message sending unit 112 for sending messages and a control unit 111 for controlling the entire embodiment.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2.
This will be explained using the following.

It is now assumed that the key telephone device of this embodiment is installed in a dormitory or an apartment. Extension TEL102
If the person using the extension TEL 102 is not nearby, a call is received from the dial-in line 101 (S1).
．． PBX dial-in INF110, extension TEL10
Upon receiving the extension designation number 2 (S2), the control unit 111
causes the extension TEL 102 to ring for an incoming call via the ESI 114 (S3).

[0011] At this time, since the user is not near the extension TEL 102, naturally there is no response (S4). Here, the control unit 111 counts the time until a response using an internal clock circuit, and if there is no response after a preset certain period of time (S5
), and causes the ESP 113 to send a corresponding call message (This is Mr. XXX's phone) according to the extension designation number received earlier to the message sending unit 112 (S6). ESP
113 is broadcast into the dormitory or apartment by an external speaker 104.

[0012] After this, the called party who has heard the message from the external speaker 104 uses an extension key telephone nearby,
For example, when an incoming call is answered by dialing a predetermined special number from the extension TEL 103 (S7), a call state is established (S8).

[0013]

As described above, the present invention provides a main device with a message sending unit that stores and sends a plurality of predetermined calling messages for calling the respective users of a plurality of extension button telephones, If the called party does not answer within a predetermined period of time when the dial-in line receives a call,
By having a control means that uses a paging function to send a calling message from a message sending section to call a button telephone corresponding to an extension designated number arriving from a dial line, the user of the extension button telephone can press the extension button when an incoming call is received. Even if you are not near a telephone, if you are in a dormitory or apartment, you will be automatically paged and can answer the incoming call.
