Abstract

PURPOSE:To improve the operability by forcibly executing release of mute when a talking state by a hand-free function is switched into a usual talking state with a handset lifted up. CONSTITUTION:A mute function is assigned to a button 28 and every time the button 28 is depressed, mute setting/release is implemented. When the handset is lifted up, the mode selection to execute mute release is implemented by using at first a dial button for special number dialing and depressing the dial button for 1 or 0. That is, when the dial button '1' is depressed after dialing of a special number, the mode to release mute forcibly is selected with the handset lifted up and when the button '0' is depressed, the mode not releasing mute forcibly is selected when the handset is lifted up. Moreover, the system stores selection information to a RAM 7 for each telephone set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone switching device that accommodates a telephone having a hands-free function and a mute function.

[Prior Art] Conventionally, in this type of device, the functions of a telephone are controlled by commands from a main device that controls the entire system.

For example, regarding the mute function, the information that the user has pressed the mute button is once notified from the telephone to the main device, and the main device sends a command to set or cancel mute to the telephone, and the mute function is executed.

[Problems to be Solved by the Invention] However, in the above conventional example, the mute state is simply switched by pressing the mute button.
For example, in a telephone in which the mute function is effective not only for the microphone during hands flow but also for the handset's transmitter, the following inconvenience occurs.

In other words, if a user wants to talk on the handset during a hands-free call with mute enabled, simply turning down the handset will not cancel mute, and pressing the mute button will not cancel mute. button to cancel the mute state.

Therefore, in this case, two operations are required: turning off the handset and pressing the mute button, which is cumbersome and disadvantageous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone switching device that can properly execute or cancel the mute function in a hands-free call state and a normal call state with the handset raised, thereby achieving improved operability. do.

[Means for Solving the Problems] The present invention is directed to a telephone exchange that accommodates a telephone as an extension having a hands-free function and a mute function for both a microphone and a handset.

a mute instruction means for instructing setting and release of mute;
A selection means for selecting unmute when lifting the handset, and when unmuting when lifting the handset is selected by the selection means.

The present invention is characterized by having control means for maintaining the mute state based on the operation of the mute instruction means when the handset is lowered, and forcibly canceling the mute when the handset is raised.

[Function] According to the present invention, when a call state using the hands-free function is switched to a normal call state with the handset raised based on the mode setting by the selection means, regardless of the mute state at that time, the forced Unmute is executed automatically.

As a result, it is possible to obtain an unmuted state simply by lifting the handset, so there is no need to press the mute button at this time, and operability can be improved.

[Embodiment] FIG. 1 is a block diagram showing the configuration of a main device 2 and a telephone 20 of a key telephone device according to an embodiment of the present invention.

The main device 2 includes an outside line interface 3 that detects incoming calls from the outside line 1 and sends out dial messages, a call path switch 4 that exchanges/connects outside lines, extensions, sound sources, etc., and an extension interface 5 that accommodates the telephone 20. A control device 6 that controls the system, a RAM 7 that stores information necessary to operate this system, such as whether or not mute is released when the handset is lifted, the mute state when the handset is lifted, and other information necessary to operate the system. The sound source 9 includes a ROM 8 in which programs and the like that determine the operations of the sound source 9 are stored.

-On the other hand, the telephone 20 sends voice information and control information to the main device 2.
, a speech network 22 for connection connection, a handset 23 for sending and receiving calls, a speaker 24 for receiving calls during hands-free calls, and a microphone 25 for sending calls. ,
A control device 26 that controls the operation of this telephone, a dial button 27 for dialing, a function button 28 that can be arbitrarily assigned a specific meaning on this system under the control of the main device 2; L attached to
It has an ED 29 and a display device 30 that visualizes dialed numbers and the like under the control of the main device 2.

In this embodiment, a mute function is assigned to the function button 28, and mute control is performed according to a procedure described later.

To assign the mute function to the function button 28, first use the dial button to select a special number indicating the task to assign to the function button, then press the corresponding function button, and finally assign the code corresponding to mute. is input using the dial button.

Through such operations, the mute section is assigned to the function button 28, and from now on, each time this button 28 is pressed,
You can set/unmute.

In addition, with this button operation, the LED 29 is turned on/off to display the operation status.

Next, mode selection for canceling mute when the handset is turned off will be explained.

To select this mode, first operate the special number using the dial button, then press "1" or "0" on the dial button.
This is done by pressing . In other words, after the special number operation,
Pressing ``1'' selects a mode in which mute is forcibly canceled when the handset is lifted up, and pressing ``0'' selects a mode in which muting is not forcibly canceled when the handset is lifted. Note that the system holds this selection information in the RAM 7 for each telephone.

FIG. 2 is a schematic diagram illustrating each state in this embodiment, that is, the state of the handset, the current mute state yE, and the transition of the mute state when on-hook.

Here, control will be described when the selection information is set to forcibly cancel mute when the handset is turned off.

The above-mentioned state transitions are caused by the user's on-to-two footer/off-footer actions and by pressing the mute button.

Hereinafter, the state in which the handset is raised will be referred to as off-hook, and the state in which it is lowered will be referred to as on-footer.

For example, when the user is in a hands-free state (on-hook state)
Let's say you're talking on a call with the microphone enabled (mute off). This case corresponds to state number Sl in FIG.

At this time, if the mute button (function button 28) is pressed so as not to send out the sound, the current mute state is turned on, and the mute state at the time of the on-footer is turned on, and the process moves to state S2.

Since the setting is to cancel muting when off-hooking in S2, the current mute state is turned off and the process moves to S5.

In other words, even if mute is turned on, the user can unmute it by lifting the handset. However, this is temporary, and if you turn the footer on again in this state, the mute-on state S
Return to 2.

In this way, regardless of the current mute state yE, muting can be canceled by going off-hook, and returning to the previously set state by going on-hook.

Note that if the setting is not to forcibly release the mute when the handset is put up, the mute control is performed only by the mute button 28, as in the conventional example.

Note that the present invention is not limited to the embodiments described above, and various modifications are possible.

For example, the current mute state may be indicated on the display device 30 rather than on the LED 29 associated with the function button 28.

[Effects of the Invention] As described above, according to the present invention, the operation of raising and lowering the handset and the cancellation of mute can be linked according to the user's selection, and operability can be improved.
