You will need to make settings to indicate that it is connected.

Figures 3 and 4 show the main unit (hereinafter referred to as KSu) based on the recording operation when the voice response message of an absent person is stored in VRuS in advance according to the extension number of the handset 4 through the registration operation of the handset 4. 1 and VRu5, respectively.

First, in FIG. 3, when any handset 4, that is, the calling party dials the number of the called party (step 101),
KSul receives the data, determines whether the called party is VRu5, and determines whether the VRu is busy (102, 103). At this time, the called party
If not, perform extension individual call processing (105),
If the VRu 5 is busy, it sends out a busy tone to the calling party (106).

Then, if the VRu 5 is not busy, an extension individual call process is performed (step 104). Next, the calling number (
After transmitting the call (107) and receiving a response from the VRu 5 (108), the extension call processing is performed (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 VRu5 (111), and if it is in an extension call,
Send the recording button code to VRu5 (112),
The end of the bell tone of the V Ru is determined (by caller on-hook or timeout) (step 113), and after the recording is finished, termination processing is performed (step 114). In addition, step 1
If the caller does not press the recording button in step 10, other button processing will be performed (step 115).

Next, the recording operation of VRu5 will be explained with reference to FIG. 4. □VRu5 performs the extension individual calling process in step 104 of KSul, and based on this, the VRu5 performs an extension call (extension lamp; i-call (i-eottd)). ) along with the calling number (steps 201, 202),
Send response or offload code to KSu (
203) o And the extension lamp is i-use (l-
When it becomes (former ■), it becomes an extension call state (204).

Next, after starting the timer (205) and receiving a recording command from KSu (206), it starts a timer for checking the end of recording (207) and registers the calling number (208). ). At this time, if there is no recording command from KSu, it is determined whether or not there is a timeout (210), and if the timeout occurs, an on-huf coder is transmitted to KSu (211). Next, in step 208, after registering the calling number, the voice recording/playback circuit 5

(213), sends the KSu on-hook code (214), and when the timeout does not occur, stops the voice recording/playback circuit 56 when the caller goes on-hook (215, 216).

Therefore, from any handset (extension phone) 4 to VR
By accessing u5 by extension, 9, KSu
l sends the calling number of handset 4 to VRu5,
After the VRu5 responds, the recording operation records its own voice response message to the voice recording/playback circuit 5 in the VRuS.
6 can be recorded arbitrarily in its own storage area.

Next, FIG. 5 and FIG. This will be explained with reference to the flowchart in FIG.

In FIG. 5, when the caller performs an extension dialing operation, KSul receives the data in step 301), determines whether the called party is forwarded to the call, and determines whether the forwarding destination is VRu5 (step 302). , 303), the transfer destination is VRuS
If so, perform extension calling processing to that VRu (304), and send the calling number and called number to the VRu (305) o At this time, if the called party does not set call forwarding, (302) and performs normal extension call processing (31)
1), and if the transfer destination is not VRu5 (30
3) Performs extension call processing to the forwarding destination (312). Next, after sending the calling number and called number to VRu5 (305
), when VRu5 responds (306), KSul:
After receiving it, the extension call is processed (307), and after determining whether or not the message is terminated for the absent called party (308), the message is terminated or the caller abandons the call (315). ) Performs end-of-line call processing (3)
09). However, if there is no extension call operation in step 301, other button processing is performed (step 310), and if there is no response from VRu5 in step 306,
The call termination process for the extension call is performed depending on whether or not the caller performs an abandon operation (314).

On the other hand, in FIG. 6, when the VRu 5 receives an extension call (step 401) and receives the called number (step 402),
It is determined whether the called number is registered (403), and if it is registered, a response signal (off-hook code) is sent to KSul (404), and when KSul responds (405), The VRu 5 sends the called party's absence message for a certain period of time (406), and when the message sending is finished (407), sends an on-hook signal to the KS.
ul (40B of the same), and if the message sending is not completed, the caller's abandonment operation is sent (410B of the same).
), the operation ends.

Note that in step 403, if the called number is not registered, a busy tone is sent to KSul.

In this way, according to the present embodiment, the voice message is sent to the VRu 5 according to the extension number by the registration operation of the handset 4.
After setting up call forwarding for VRu5 and making an extension call to the handset with call forwarding settings, KSul will forward the incoming call to VRu5 and set the caller handset number. , sends the called handset number (handset in call forwarding). Then, VRu5 responds (sends an off-hook code) to KSul.
5 is capable of making the calling handset listen to the voice message of the handset during call forwarding. [Effects of the Invention] As explained above, according to the button telephone device of the present invention, the voice message of the handset during call forwarding can be heard by the calling handset. When the caller sets call forwarding and calls an extension to an absent called party, the call is transferred to the voice response device and the absentee's voice message can be heard, so the caller can call the extension. This also has the effect of improving the voice service function by being able to respond to absentee calls.
