Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a telephone system such as an electronic private branch exchange (PBX).

(Prior Art) Conventionally, a PBX system is configured as shown in FIG. Here, when an incoming call arrives at the trunk circuit 4, the central control circuit (microprocessor) 5 of the exchange 1 executes the trunk circuit 4 based on the program of the flowchart shown in FIG. A so-called direct in-line system for calling a plurality of predetermined extension telephones 8 associated with the system is adopted.

That is, an incoming call from the line 1 is detected (600), and the identification information of the called terminal is searched from a preset memory table (601). The memory 6 stores identification information of a plurality of extension telephones 8 to be called corresponding to the office line l. Through the above search, it is detected whether or not there is identification information of the extension terminal corresponding to the office line where the call was received (602),
If not, an incoming call is generated at a relay console (not shown) (calling is performed) and the process ends (603).

On the other hand, if there is identification information in step 602,
It is detected whether or not the corresponding extension terminal is busy (604). If not, a call signal is given via the line circuit 7 (60).
6) It is checked whether or not all the identification information of the extension terminal corresponding to the receiving office line has been searched (607). Here, if there is still any remaining, the next identification information is obtained (608), and step 6
Return to 04 and continue operation. If it is determined in step 604 that the terminal is busy, the busy terminal is camped on, and the terminal enters a waiting state (605). In this way, the above operation is continued until the search for all the identification information of the extension terminal corresponding to the incoming office line is completed.

For this reason, if there are incoming calls on the same office line one after another, the call is picked up at one time and the call is terminated, and the next call is made during the paperwork related to this call, which is troublesome. Was.

(Problems to be Solved by the Invention) As described above, in the conventional telephone system, in the direct line system, when an incoming call is received on the relevant office line, the same extension terminal is called, and after the end of the call, some administrative processing is performed. For those who go, there is a problem in that the call is urged, and the user is troublesome and inconvenient.

The present invention has been made in order to solve the problems of such a conventional telephone system, and its purpose is to be able to temporarily reject a call if necessary, An object of the present invention is to provide a telephone system that can automatically recover as a call destination when a call arrives at a predetermined office line.

[Structure of the Invention] (Means for Solving the Problems) A telephone system according to the present invention comprises means for registering call rejection setting information for an extension terminal and a plurality of calls to be called when a call is received from a line. Storage means for storing the identification information of the extension terminal according to the destination candidate corresponding to the line, and storing information indicating whether or not call rejection is set for each extension terminal; An incoming call rejection management unit that manages information indicating whether or not an incoming call rejection is set in the storage unit based on the timing information of the timekeeping unit and the setting information of the registering unit, and an incoming call from the line is detected. In the case, it is sequentially detected whether or not the telephone is busy based on the identification information of the extension terminal stored in the storage means corresponding to the line and for which the setting of call rejection is not made, and whether or not the telephone is busy This When a call is made to a detected extension terminal and a busy extension terminal is detected, data indicating that there is a call waiting for incoming calls is created according to the identification information of the extension terminal. When the call is recovered from the busy state, the extension terminal is provided with a function to cause the extension terminal to receive an incoming call. Terminal control means for the terminal.

(Operation) According to the above configuration, the setting information is registered by means for registering the setting information of the temporary termination of the extension terminal. As a result, a temporary call rejection setting for the extension terminal in the storage means is made, and then the setting can be canceled based on the timer. Then, since the incoming call control means uses this information to call the extension terminal corresponding to the office line, temporary incoming call rejection becomes possible when necessary.

Then, when an incoming call from the line is detected, it is determined whether or not the telephone is busy based on the recognition information for which the incoming call rejection is not set among the identification information of the extension terminals stored in the storage means corresponding to the line. Are sequentially detected and the operation of making a call to the extension terminal that is detected to be not busy is performed for the extension terminals as long as they are stored corresponding to the line. Extension terminals that do not have call rejection set among the extension terminals are appropriately called. Also, when a busy extension is not called and a busy extension terminal is detected, data indicating that there is a call waiting for reception corresponding to the identification information of the extension terminal is created. An extension terminal as long as it is prepared to generate an incoming call at the extension terminal when the call is recovered from the busy state, and the operation of putting the call into a call waiting state for the extension terminal is stored for the line. So if the call is not made due to busy,
The extension terminal restored from the busy state is called appropriately.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, 8 ₁ to 8 _n represents an extension telephone. A key 81 for registering temporary rejection of call
An LED 82 is provided. When the key 81 is operated, setting information for temporarily rejecting incoming calls is transmitted from a control (not shown) inside the extension telephone 8. 101 indicates a storage unit, which includes the stored identification information of the extension telephone 8 to call in response to an incoming call to the office line l ₁ to l _m, and each identification information together with the extension telephone 8 is temporarily A flag is provided to indicate whether or not a rejection of an incoming call has been registered. Reference numeral 102 denotes an incoming call rejection management means, which is provided with a timer 103.
When the setting information is transmitted by the operation of (1), it is detected, a graph paired with the identification information corresponding to the extension phone 8 is set, and the timer 103 sets a predetermined time (for example, (3 minutes or 5 minutes) is detected, and at this time, the corresponding flag is reset. 104 denotes a reception control means, when there is an incoming call to the office line l ₁ to l _m, refers to the memory table corresponding to the office line according to the incoming of the storage means 101, the flag is not set to the extension telephone 8 Make a call.

FIG. 2 shows a PBX system that performs such control.
In the figure, 1 indicates a switch, the trunk circuit 4 ₁ to 4 _m
It is connected to the office line l ₁ to l _m through. Line circuit 7 ₁
It is connected to the extension telephone 8 ₁ to 8 _n to 7 _n. 2 shows the speech path line, performed between line circuit 7 ₁ to _7-n, the formation of a voice communication path between the line circuit 7 ₁ to _7-n and trunk circuits 4 ₁ to 4 _m.
Reference numeral 3 denotes a bus through which the central control circuit 5 transmits and receives data to and from each unit. The central control circuit 5 has a memory 6 and a timer 10
3 is connected.

In the above, the central control circuit 5 functions as the incoming call rejection management means 102 and the incoming call control means 104 based on the program in the flowchart shown in FIG. 3 and FIG.

That is, when there is an incoming call from the station line 1, this is detected (40
0), searching the memory table as shown in FIG. 1 in the memory 6 to check whether there is identification information (401, 402), and if not, causes a not-shown relay console to generate a ringing tone (40).
3). On the other hand, when the identification information is stored, the extension telephone 8 associated with the first identification information in the corresponding memory table is stored.
Is detected whether or not a temporary call rejection setting has been made (whether or not a flag has been set) (40).
Four). If not set, it is detected whether or not the extension telephone 8 is busy (406). If you are not busy here
A ringing tone signal is sent to the extension telephone 8 to generate a ringing tone (407). On the other hand, if it is detected in step 404 that the incoming call rejection has been set, or if it is detected in step 406 that the terminal is busy, the terminal is camped on (the call in the waiting state and the extension Creates data of identification information with the telephone.) Waiting state (405),
Proceed to step 408.

In step 408, it is detected whether or not the next identification information is present in the memory table corresponding to the station line 1 on which the call has been received, and it is checked whether all the identification information has been searched. 409), returning to step 404 to continue the operation.
When the search for all the identification information is completed, the process ends. As a result, a call is made to the extension telephone 8 for which temporary call rejection is not set.

On the other hand, when the central control circuit 5 detects the operation of the key 81 of the extension telephone 8, it sets a flag provided together with the corresponding identification information, and sends a lighting instruction signal of the LED 82 to the extension telephone 8 to light the LED 82. Let it. Then, according to the flowchart of FIG. 4, a time-up is detected with reference to the timer 103, and when the time-up occurs (501), a flag provided together with the corresponding identification information is reset (502). On the other hand, it is detected whether there is a camp-on call (503), and if so, a call signal is given to the extension telephone 8 corresponding to the identification information to make a call (504). Further, a control signal is given to turn off the LED.

With the above configuration, it is possible to temporarily reject incoming calls when necessary, and to return to the direct-in dialing group after a short time.

The time-up time of the timer 103 is determined in advance.
The maintenance terminal is connected to the central control circuit 5, or is registered as appropriate using the extension telephone 8 for setting predetermined operation data. In addition, the time period for receiving temporary call rejection,
For example, AM 5:00 to PM 6:00 may be set in the memory 6 by the above method. As a result, the response becomes poor due to the rejection of the call outside the above-mentioned time zone, and the trouble of the partner is reduced.

Further, in the above embodiment, a special key is used, but a specific dial number may be input to set a flag. In addition, temporary rejection of incoming calls may be performed not only for office lines but also for internal calls.

[Effects of the Invention] As described above, according to the present invention, it is possible to temporarily reject incoming calls when necessary, perform business processing after the end of a certain call, and again receive an incoming call to the line. Can be restored as a calling terminal. Therefore, usability can be improved.

Also, according to the present invention, when an incoming call from a line is detected,
It sequentially detects whether or not the telephone is busy based on the identification information of the extension terminal stored in the storage means corresponding to the line and for which call rejection is not set, and detects that it is not busy Operation to make a call to the designated extension terminal,
Since the process is performed for the extension terminals that are stored corresponding to the line, the extension terminals that are not set to reject incoming calls among the extension terminals associated with the line are appropriately called, and the response is poor. Prevent from becoming. Further, even when a call is not made due to a busy call, when an extension terminal that is busy is detected, data indicating that there is a call waiting for reception corresponding to the identification information of the extension terminal is created. An extension terminal as long as it is prepared to generate an incoming call at the extension terminal when the call is recovered from the busy state, and the operation of putting the call into a call waiting state for the extension terminal is stored for the line. Therefore, even when a call is not made due to a busy call, the extension terminal recovered from the busy state is appropriately called and the response is prevented from being deteriorated.
