The main unit is provided with control means for controlling the hands-free function for the calling button telephone which has operated the above-mentioned key when the response to the call is detected. Further, the main device is provided with an end-of-call control means for automatically turning off the hands-free function of the calling button telephone in response to the end of the call of the called telephone responding to the call.

Further, the extension number is registered in the memory in correspondence with the key, and the calling means calls the key telephone when the operation of the key is detected by the detecting means. Further, the main device is provided with a judging means for judging whether or not there is a call state of each of the other key telephones when the detecting means detects an operation of the key, and the calling means judges that the call state is not present. In this case, the key telephone corresponding to the extension number is called, and when the determination means determines that there is the call state, the key telephone in the call is called.

[0007]

When the operation of the predetermined key is detected, a call is made according to the telephone number registered corresponding to this key, and
When a response to the call is detected, the hands-free function is controlled to the ON state for the calling button telephone which has operated the above keys. As a result, after calling by one-touch operation, it is possible to automatically talk with the called party. Also,
When the call termination of the called telephone that has answered the call is detected, the handsfree function of the call button telephone is turned off and the call is automatically terminated. As a result, the call button telephone is automatically set to the idle state without any special operation at the end of the call.

Further, an extension number is registered corresponding to the key, and when the operation of the key is detected, an extension call is made to the key telephone. Therefore, if this device is installed in, for example, a hospital or a facility where people with disabilities are accommodated, a call is automatically made after calling the nurse who is the called side of the extension with one-touch operation. It becomes possible to automatically end the call without any special operation. Also, when the operation of the above keys is detected, it is determined whether or not there is a call state of each of the other key telephones, and when each telephone is not in the call state, the key telephone corresponding to the registered extension number is called and If any one is in a call state, the key telephone in the call is called. As a result, when an emergency is required, the other party who is actually in a call is called from an empty telephone that may be absent, so that it is possible to reliably contact the other party when an emergency situation occurs. .

The key telephone 5 is provided with a call circuit 51,
It is composed of a transmission circuit 54 that performs data transmission with the main device 1, a control unit 55 that controls the key telephone 5, a display circuit 56, a keyboard 57, a speaker SP, a microphone MIC, and the like, and has a hands-free function. Here, the keyboard 57 includes an outside line key A including a plurality of outside line buttons, a dial key B, a hold key C, an automatic key D including a plurality of auto dial buttons, an emergency key E, and the like.

When the off-hook operation is performed on the key telephone 5, the control unit 55 detects the off-hook from the state of the hook switch HS and transmits the off-hook information to the main unit 1 via the transmission circuit 54, and then the keyboard 57. When the operation of the outside line key A is detected, this operation information is transmitted to the main device 1. In this case, when the CPU 14 of the main device 1 receives this outside line key operation information via the telephone interface 13, it controls the corresponding outside line interface to capture the outside line.

After that, when the auto key D of the keyboard 57 of the key telephone 5 is operated and this operation information is transmitted to the main unit 1, the CPU 14 of the main unit 1 RA
The auto-dial number registered in the area of the key telephone of M16 is read out and sent to the corresponding outside line interface to send the corresponding dial signal to the captured outside line.

RAM 16 corresponding to the auto key D
If the extension number is registered in the inside, the button telephone corresponding to the extension number automatically registered can be called by one-touch operation of this auto key. In this embodiment, the key telephone 5 is provided with the above-mentioned emergency key E as a device corresponding to such extension automatic dialing.
An extension number is registered corresponding to the emergency key E, and when the emergency key E is operated, the corresponding key telephone is automatically called. When calling by operating the emergency key E, the key telephone on the calling side is set to a hands-free call state via the speaker SP and the microphone MIC.

By setting the telephone set of the calling side to the hands-free state in this manner, it becomes possible to talk with the other party who answered the call without going off-hook. When arranged in a facility where free people are accommodated, these people can call the other party freely after calling the other party by one-touch operation. Further, since the device automatically performs the end call processing after the call ends, the end call operation such as the on-hook operation at the end of the call becomes unnecessary.

Next, FIGS. 2 and 3 are flowcharts showing the operation of the CPU 14 of the main unit 1 having such a one-touch dial transmission function. The operation of the main part of the present invention will be described using these flowcharts. First, in step S1 of FIG. 2, it is determined whether or not the emergency key E of the key telephone (hereinafter referred to as a handset) is pressed. When the pressing of the emergency key E of the handset is detected, the handset is not in the on-hook state. Whether or not it is in use is determined in step S2.

If the cordless handset that operated the emergency key is unused, it is determined in step S3 whether or not another cordless handset is in use, and if no cordless handset is in use. ,
In step S4, a call is made to the slave unit corresponding to the extension number registered in the slave unit area in the RAM 16 corresponding to the emergency key. And the cordless handset (calling handset)
A ringback tone is transmitted in step S5.

When an off-hook operation indicating a response of the called-side cordless handset (calling-destination cordless handset) is detected in response to the calling of the calling-side cordless handset and the determination in step S6 becomes "Y", step S7 is performed. Then, the ring back tone of the calling handset is stopped, and the call path switch 12 is controlled to connect each of the calling side and the called side handsets to the extension call path to start an extension call. Then, at this time, in step S8, control data for turning on the speaker SP and the microphone MIC is transmitted to the calling device to turn on the hands-free function. That is, in this case, the control unit 55 of the calling handset turns on the speaker SP and the microphone MIC via the calling circuit 51, so that the calling handset enters the extension hands-free call state.

After that, the process proceeds to steps S9 and S10 of FIG. 3 to judge the termination of the incoming caller and the termination of the calling slave, respectively. When the on-hook operation of the called terminal is detected and the determination in step S9 is "Y", the call path switch 12 is controlled to open the call path for the extension call in step S11, and the call path is issued in step S12. Control data for turning off the speaker SP and the microphone MIC is transmitted to the call subunit to turn off the hands-free call, and the process returns to step S1 in FIG. 2 to enter the standby state. When the call end operation of the calling handset is detected and the determination in step S10 becomes "Y", the call path switch 12 is controlled to open the call path during the extension call in step S13, and step S14.
Turn off the hands-free call of the calling machine with. After that, in step S15, busy tone data is sent to the called terminal to sound the busy tone, and when the call termination of the called terminal is detected and the judgment in step S16 becomes “Y”, the called terminal is called in step S17. Send busy tone off data to stop busy tone ringing.

As described above, since the calling handset is set to the hands-free state at the time of extension call based on the operation of the emergency key, the calling handset can talk to the other party without any operation. it can. Further, since the calling terminal can automatically end the call when the called terminal ends the call, the operation for ending the call becomes unnecessary. On the other hand, if the cordless handset that has operated the emergency key is in an unused state, and there is a cordless handset in this system at that time, and the determination in step S3 in FIG. 2 is "Y", this is determined in step S21. Make a call to a cordless handset (busy call). Then, in step S22, a ringback tone is sent to the calling terminal. Next, in steps S23 and S24, it is determined that the call termination of the called terminal and that the outside call of the called terminal is in progress, respectively.

When the call of the called handset is completed and the judgment in step S23 becomes "Y", the process proceeds to step S6. At this time, if an off-hook operation of the called handset is detected, an extension call after step S7 is performed. Move to processing. If the called slave is in an outside line call and the determination in step S24 is "Y", the operation of the hold key C of the called slave is detected in step S25. When the hold key C is operated on the called terminal, the outside line is held at step S26, and the process proceeds to step S7 to connect the extension call path between the called terminal and the calling terminal so that both the terminals can be connected. Make an extension call.

As described above, when an extension call is made based on the operation of the emergency key E, the call is made to the active handset regardless of the registered extension number. As a result, in an emergency, an unoccupied handset that may be absent calls the other party who is actually in a call, so that when the emergency situation occurs, the other party can be surely called and contacted.

In the present embodiment, an example of calling an extension by registering an extension number corresponding to an emergency key has been described. However, a dial number of an outside line is registered to automatically capture an available outside line. You can also dial.
In this case, when the caller's response is detected, the calling device is set to the outside line hands-free state, and when the other party's call end is detected by detecting the reversing signal, for example, the outside line is automatically opened and the calling device is set. It is configured to release the hands-free and terminate the call.

[0024]

As described above, according to the present invention, when an operation of a predetermined key is detected, a call is made according to a telephone number registered corresponding to this key and a response to the call is detected. Then, the hands-free function is controlled to be ON for the calling device that operated the above keys, so after calling with one-touch operation, you can automatically call the callee without any special operation. It can be carried out. Also, when the call termination of the called telephone that answered the call is detected, the hands-free function of the calling handset is turned off and the call is automatically terminated. The calling device can be automatically returned to the idle state.

Further, since the extension number is registered in correspondence with the key and the operation of the key is detected, the extension call is made to the child device in the apparatus. If it is installed in a facility where people with disabilities are accommodated, it will be possible to call the nurse, who is the called side of the extension, by one-touch operation, and then automatically make a call. When talking, you can automatically end the call without any special operation. Also, when the operation of the above key is detected, it is determined whether or not there is a call state of each of the other handset units, and when each handset unit is not in the call state, the handset unit corresponding to the registered extension number is called and When any one of the machines is in a call state, the call is made to the cordless handset. Therefore, in an emergency, the other party who is in the call is available from the idle cordless handset that may be absent. By calling, it is possible to reliably contact the other party when an emergency situation occurs.
