Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button telephone device,
In particular, the present invention relates to a key telephone device having a call forwarding function.

[0002]

2. Description of the Related Art A conventional key telephone device of this type will be described with reference to the drawings. FIG. 3 is a block diagram showing a first conventional example.

In FIG. 3, this first conventional example shows the contents disclosed in Japanese Patent Application Laid-Open No. 4-165895 "button telephone device", and is mainly used when an extension group 21 (representative number 300) receives an incoming call. The main control unit 102 in the device 101 is
The contents of the group extension number storage unit 107 in the data unit 105 are referred to and an incoming call is made to an empty key telephone in the group. At that time, timer A (for example, 10 seconds) and timer B (for example, 20 seconds) are started.

If the key telephone does not respond even if the timer A times out, the group extension number storage unit 107 makes an incoming call to the key telephone in the same group and similarly activates the timer A. Even if the timer B times out, if all the key telephones in the group do not respond or if a call is in progress, the main control unit 102 in the main device 101 stops the incoming call to the extension group 21,
The data unit 105 and the transfer destination data number storage unit 108 are referred to and an incoming call is made to the key telephone set in the specified extension group 22.

Under the control described above, an incoming call to the extension group 21 (representative number 300) is received by the extension group 22 (representative number 3).
01) is executed.

FIG. 4 is a block diagram showing a second conventional example.

In FIG. 4, this second conventional example shows the disclosed contents of Japanese Unexamined Patent Publication No. 4-79453, "button telephone device". When a caller makes a call, an incoming signal arrives at an incoming station line 202. . The incoming line signal is detected by the office line interface unit 204, and the detection signal is sent to the control circuit unit 209.
The control circuit unit 209 which received it sends a dial from the other station line interface unit 205 and transmits to the transfer destination.
As the state of the transfer destination at that time, the following two states of the response and busy can be considered.

The response from the station line interface unit 20
The polarity inversion is detected at 4 and it is determined that the response is the other party, and the switch unit 206 connects the incoming station line 202 and the forwarding station line 203 to complete the transfer.

During busy, the busy tone detecting circuit section 207 detects a busy tone coming from the transfer station line 203, judges the busy state, and sends a detection signal to the control circuit section 209. The control circuit unit 209 that receives the message connects the incoming call line 202 and the message sending / recording unit 208 by the switch unit 206, and stores a busy message that is registered in advance, such as "Answer other telephone now. I'll call you later. Please give me the number. "And also record the caller's message, such as the phone number. Then, after the caller's message has been recorded, the key telephone device waits for a while, and automatically transmits again to the transfer destination, and after replying, sends the recorded message.

[0010]

In the conventional button telephone system described above, in the case of the first conventional example, the main control unit receives the incoming call of the representative number of one of the plurality of extension groups by the control means. In the case of an emergency call, if there is no response from the key telephone set in the extension group or the extension telephone set does not respond within a predetermined time based on the contents of the representative number storage section and the extension number storage section When all calls are in progress, the call is forwarded to another extension group or button telephone specified based on the contents of the transfer destination data number storage section. Without being informed
There is a problem that the incoming call is transferred.

Further, in the case of the second conventional example, when the transfer destination is busy, an automatic response is made once, the caller is informed that the caller is busy, the caller's message is recorded, and the call is sent for a predetermined time. After that, it is configured to redial the call to the transfer destination and transfer the recorded message after the other party responds, so when the call arrives at the transfer destination while busy, the call is transferred at the transfer destination. Since I do not know immediately, there is a problem in that I cannot receive direct contact such as an emergency.
