By connecting the VRU5 to the CNm, it becomes possible to configure the same data transmission and data code as a normal key telephone from the perspective of the KSU1. However, 1. V
Regarding the functions specific to the RU5, settings must be made to indicate that the VRU5 is connected to that port in the KSUl system programming. Figures 3 and 4 show how to register voice response messages in advance on the handset 4. VR corresponding to the extension number of the handset
3 is a flowchart of the main unit (hereinafter referred to as KSU) 1 and the VRU 5 based on the recording operation when storing in the US.

In FIG. 3, when the caller dials the number of the called party (step 101),
KSUl receives the data and determines whether the called party is VRU5 and also determines whether that VRU is busy (102, 103) o At this time, if the called party is VRIJ5.
If not, perform extension individual call processing (105),
Further, if the VRU 5 is busy, it sends out a busy tone to the calling party (106). And if VRU5 is not busy,
Individual extension call processing is performed (104). Next, VR
Called number C to U 5 (NO,) f) Send M wo line (107), and when a response comes from VRU 5 (108)
), performs extension call processing (109).

On the other hand, if the calling party does not dial the number of the called party in step 101, when the calling party presses the record button (which can be replaced with a dial button) (step 110), the KS
Ul receives the data and determines whether or not an extension call is in progress with the VRU 5 (see 111), and if it is an extension call, it sends a recording button code to the VRU 5 (see 112).
, the end of recording of the VRU is determined by the caller's on-hook or timeout (step 113), and the end processing is performed after the recording is completed (step 114) o Note that if the caller does not press the recording button in step 110, ,
Other button processing will be performed (115).

Next, the recording operation of the VRU 5 will be explained with reference to FIG. When the VRU 5 performs the extension individual calling process in step 104 of KSUl, the VRU 5 receives the extension call (extension lamp: I call (1-call)) and the calling number (steps 201 and 202).
Send a response to the SU or send an off-hook code (203). Then, the extension lamp changes to I use (1-
ullL), it becomes an extension call state (204)
. Next, after starting the timer (205), KSU
When receiving a recording command from (206), it starts a timer for checking the end of recording (207),
Register the calling number (208) At this time, KSU
If there is no recording command from I, it is determined whether or not there is a timeout (210), and if it times out, a recording code is sent to KSU (211). Next, in step 208, after registering the calling number, the voice recording/playback circuit 56 is activated to store the voice response message from the caller (step 209), and when it times out (step 209).
12), the audio recording/playback circuit 56 is stopped (213), and the KSU heon hook code is transmitted (213).
14). If the timeout does not occur, the voice recording/playback 2856 is stopped by the caller's on-hook (steps 215 and 216).

Therefore, from any handset (extension phone) 4 to VR
By making extension access to U5, 9, KSU
l transmits the calling number of the handset 4 to the VRU 5,
After the VRU 5 responds, its own voice response message is recorded by the voice recording/playback circuit 56 in the VRU S by a recording operation.
You can arbitrarily record in your own storage area.

Next, after storing the voice response message in advance in the VRU 5 in correspondence with the extension number of the caller's extension telephone in this way, when the extension telephone concerned is talking to an outside line or extension, another handset (extension telephone ) 4 will be described with reference to FIGS. 5 and 6. Here, FIGS. 5 and 6 show flowcharts of KSUi and VRU 5, respectively, when a voice call is made from an extension.

First, in FIG. 5, when the extension telephone of any handset 4 receives a voice call from another extension telephone during a call, when the extension telephone performs a transfer operation to the VRU 5 using the function button (step 301), KSUl
receives the data, determines whether the operating telephone is in a call with another person, determines whether a voice call is being received (302, 303), and determines whether all VRUs 5 are busy. (304) o At this time, if all VRU5s are busy, a busy tone is sent to the caller (311);
If all RU5s are not busy, KSU1 makes an individual extension call from the caller to VRU5 (305). Next, the called number code (indicating the number of the telephone for transfer operation to the VRU) is sent to the VRU 5 (306), and the VR
After sending the playback code to U5 (3Q7), VRU5
It is determined whether or not there is a response (308), and if it responds, the extension call processing is performed (309). Note that if there is no transfer operation to the VRU 5 in step 301, other button processing will be performed (step 310).

On the other hand, in FIG. 6, when the VRU 5 receives an incoming extension call (step 305) for individual extension calls of KSUl (step 401), it determines whether it is receiving a playback code or a called number code, and then ( 402.403
), determine whether the called number code has been registered (404
) o At this time, if the called number code is not registered, K
A busy tone is sent to SUl (410), but if the called number code is already registered, KSIJI"<response data (off-hook code) is sent (405) and V
If KSU1 responds (406), RU 5 transmits the voice recording/playback circuit 56 to the voice area corresponding to the called number.
407, 408), and determine the end of the playback.
Same as 40 when sending SUI headphone code.
9) If the playback is not finished, the operation is finished by the caller's on-hook operation (411).

As described above, according to the present embodiment, when the extension telephone of any handset 4 receives a voice call from another extension telephone during a call, when the extension telephone performs a transfer operation to the VRU 5, the KSUl is Transfer calls from other extensions to the extension telephone to VRU5 (transfer calls from other extensions to VRU5)
(controls the form of an extension call to the RU) and transmits the called number to the VRU 5 at the time of transfer. And VR
U5 checks the above-mentioned calling number and called number, and if they match, sends a response signal (off-hook code) to KSUI.
When the message is sent to K, KSU1 places both parties in an extension call state and closes the communication path between the two parties. This allows the calling telephone to hear the VRU 5's voice response message. Furthermore, if the calling number and the called number cannot be matched, a busy tone is sent to the calling party.

Although the above-mentioned embodiment has been explained using an example of an extension voice call, the present invention is not limited to this, and can be similarly applied to an extension tone call and an outside call. In other words, when you receive an incoming call from another extension telephone or an outside line call while you are busy, you can transfer the call to the VRU and receive voice service.About this To be more specific, in the case of an extension call, it is the same as in the above embodiment, but in the case of an external call, the call is transferred to the handset by a transfer operation, and the call is transferred to the VRU.
When the VRU detects the outside line incoming code, it automatically sends the KSU Ic capture code for the outside line to respond, and then receives the DTMF dial signal (access code) from the outside line with the VRU's DTMF' receiver. Once the outside line has been terminated, it can be transferred to another extension, and other controls can be freely controlled. However, in the case of incoming outside calls, it is necessary to restrict incoming calls from phones other than those at the reception desk.

Alternatively, one of a plurality of messages may be specified by the specific operation.

〔Effect of the invention〕

As explained above, according to the key telephone device of the present invention, when there is a call from another key telephone during a call, the current call state is maintained and the incoming call from the other key telephone is voiced by a predetermined operation. Since it is possible to transfer the message to the answering device and send the message stored in the voice response device in advance to the calling party, it is possible to send any message to each key telephone, improving the voice service function. effective.
