BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple exchange device, and more particularly to a simple exchange device for transmitting an outside line to a predetermined call destination in response to a special operation when an extension call partner is absent.

[0002]

2. Description of the Related Art Conventionally, in this type of simple exchange apparatus, usually, a specified extension number is inputted to call a specific party by extension, and in response to the response, the call is transferred to an extension call to communicate requirements. It has become. Here, when the call partner is absent, such as when going out, it is possible to make a telephone call to the call partner, for example, when returning home, going out to a predetermined office, PHS (Personal Handy Phone System) or mobile phone. If you have a telephone, you have to look up the telephone number and make an outgoing call.

If the caller does not recognize the absence of the call partner in advance, the caller is called by extension. Thereafter, in response to the unanswered extension call, the caller recognizes the absence, terminates the extension call once, then checks the contact telephone number of the called party, and initiates an outside call.

[0004]

Therefore, in such a conventional simple exchange apparatus, usually, when there is no other party who can communicate the requirements by extension call, the telephone number of the called party is listed in the telephone number list. If you need to find out the phone number of the destination on abbreviated dialing, etc., you need to look up the abbreviated number, then catch the outside line and dial. Is troublesome, and in some cases, there is a possibility that an incorrect call may be made due to an incorrect operation. An object of the present invention is to solve such a problem, and an object of the present invention is to provide a simple exchange device capable of transmitting an external line to a predetermined call destination by a simple operation when the other party does not answer at the time of calling an extension.

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a simple exchange apparatus according to an embodiment of the present invention, and particularly shows a key telephone apparatus as an example of the simple exchange apparatus. Note that the simple exchange device referred to here is a telephone device that accommodates an outside line and has an internal call function, and is not limited to a key telephone device, but also includes a private branch exchange (PBX) and the like. FIG.
In, 10 main unit, L ₁ ~L _n is external housed in the main unit 10, 1 ₁ to 1 _m is the main unit 10 to the key telephone that is an extension housing (hereinafter, phone hereinafter) is.

[0010] In the main unit 10, 11 ₁ to 11 _n are external interfaces to accommodate respectively each external line L ₁ ~L _n (hereinafter, external as _{I / F), 13 1 ~13} m each telephone ₁ 1 to 1 _m (Hereinafter referred to as "telephone I / F"), each of which accommodates an external line, and 12 is an external line I / F 11 _{1 to} 11 _n and a telephone I / F 13 _{1 to} 13
to form a external calls by connecting between _m, channel switch forming the extension call by connecting the telephone I / F13 ₁ ~13 _m through the interior of the extension call path, 14 key telephone system CPU that controls the whole
(Control means, detection means) and 15 are memories (storage means) for storing telephone numbers such as shortened telephone numbers and various control information.

In the telephones 1 ₁ to 1 _m , 2 is a communication circuit, 3 is a transmission circuit for exchanging various information by performing data transmission with the telephone I / Fs 13 _{1 to} 13 _m of the main device 10, and 4 is a telephone 1 ₁ A control circuit for controlling each part of up to 1 _m , 5 is a keyboard composed of various keys such as dial keys, extension keys, external keys, speed dial keys, special keys, 6 is a display circuit for performing various displays such as an incoming call display, HS
Is a hook switch for detecting an on-hook / off-hook state.

Next, the operation of the present invention will be described with reference to FIG. FIG. 2 is a flowchart showing the extension transmission processing in the CPU 14. First, any phone, for example, off-hook operation of the telephone 1 ₁ is detected by the hook switch HS, the control circuit 4, the transmission circuit 3 and the telephone I / F13
It is notified to the CPU 14 of the main device 10 via ₁ . In response, the CPU 14 captures an empty extension communication path provided in the communication path switch 12 (step 20).

[0013] Then, the operation dial key of the telephone 1 ₁ of the keyboard 5 is input extension is notified to CPU14 of the main apparatus 10 by the same route and off-hook operation of the above. CPU14 accordingly confirms the extension call party (step 21), for example, when was the extension number corresponding to the telephone 1 _m is via the transmission circuit 3 of the telephone 1 _m from the telephone I / F13 _m Then, the control circuit 4 is notified of the extension arrival and calls the extension (step 22). In response to the notification of the incoming extension, the control circuit 4 of the receiving telephone 1 _m
Controls the display circuit 6 to display an extension incoming call.

As a result, an extension is being called, and any one of answering the other party (step 23), terminating the extension transmission by the calling telephone (step 27), and special operation (first special operation) (step 28) is detected. It is repeated until it is done. If an extension response operation such as an off-hook operation is performed on the called telephone during the extension call, the CPU 14 of the main device 10 is notified in the same manner as described above, and the other party's response is detected in step 23 ( Step 23: YES).

The CPU14 accordingly connects the calling phone I / F13 ₁ and terminating phone I / F13 _m controls the channel switch 12 via the extension call path to form an extension call. Thereafter, in the extension call state, a call termination operation such as an on-hook operation by the calling or called telephone is detected (step 25), and the call path switch 12 is controlled according to the detection of the call termination (step 25: YES). The extension is released and both phones are notified of the end of the call (step 26), and a series of extension transmission processing is terminated.

If an outgoing call operation such as an on-hook operation is performed on the outgoing telephone during the extension call, the CPU 14 of the main unit 10 is notified in the same manner as described above. Is detected (step 27: YES). In this case, the extension captured in step 20 is released, and the called-end telephone is notified of the end of the call (step 26), and a series of extension transmission processing ends. As a result, the control circuit 4 of the called telephone controls the display circuit 6 to end the extension incoming call display.

On the other hand, when a special operation is performed by a special key or the like on the keyboard 5 on the calling telephone during the extension call, the CPU 14 of the main unit 10 is operated in the same manner as described above.
And a special operation (first special operation) is detected in step 28 (step 28: YES). In response to this, the extension captured in step 20 is released and both phones are notified of the end (step 29).
As a result, the control circuit 4 of the called telephone controls the display circuit 6 to end the extension incoming call display.

Subsequently, the CPU 14 of the main unit 10 performs an outside line transmission process to the absent telephone number set corresponding to the extension number of the receiving telephone. In this absent telephone number, an external telephone number such as a home or a predetermined office, or a PHS or a mobile phone is set for each extension number as a contact address when the called party is absent.

First, the absent telephone number set corresponding to the extension number of the called telephone is read out (step 30). If the absent telephone number is stored in a dedicated area provided in the memory 15 of the main device 10 in correspondence with the extension numbers of the telephones ₁₁ to 1 _m , for example, as shown in FIG. The exclusive area is searched based on the extension telephone number of the called telephone, and the corresponding absent telephone number is read.

Alternatively, the data may be stored at a predetermined position in the common abbreviated telephone number registration area as shown in FIG. 3B or the individual abbreviated telephone number registration area as shown in FIG. 3C. FIG. 3B shows a common abbreviated telephone number registration area in which abbreviated telephone numbers that can be commonly used by telephones are registered. Here, areas corresponding to abbreviated numbers “80” and thereafter correspond to extension numbers in order. Absent telephone numbers are stored.

Therefore, the storage address A of the absent telephone number corresponding to the extension number is the storage address of the absent telephone number corresponding to the first extension number, that is, the start address.
₀ , the address interval to the next absent telephone number is A _D , and the difference between the first extension number and the extension number to be read, ie, the extension number difference is N, A = A ₀ + (A _D × N) Can be calculated by

In the case of FIG. 3B, the start address A ₀
Is the storage address of the abbreviated number “80”, and the address interval _AD is the address of one abbreviated telephone number. Therefore, when the extension number to be read is “03”, the accommodation position difference N = “03” − “01” = 2, and from these actual values, the storage address of the absent telephone number corresponding to the extension number A is calculated and the absent telephone number is read.

On the other hand, FIG. 3C shows an individual abbreviated telephone number registration area in which abbreviated telephone numbers that can be used only from individual telephones are registered, and individual abbreviated telephone numbers are provided corresponding to each extension number. Absent telephone numbers are stored in predetermined abbreviated numbers in the telephone number registration area, here, the area of “00”. In this case, each individual abbreviated telephone number registration area has the same size so that the same number of abbreviated telephone numbers can be registered for each extension number, and each individual abbreviated telephone registration area is provided continuously in the order of the extension accommodation position. Have been.

Therefore, since the storage address intervals of the absent telephone numbers become equal, the storage address A of the absent telephone number corresponding to the extension number is calculated in the same manner as in the above address calculation formula. That is, in FIG.
Since the absent telephone number is stored in “0”, the start address A ₀ is the address of the abbreviated number “00” of the extension number “01”, and 10 abbreviated telephone numbers are registered for each extension number , The address interval _AD is an address of 10 telephone numbers.

Therefore, when the extension number to be read is "03", the accommodation position difference N = "03"-"01".
= 2, the storage address A of the absent telephone number corresponding to the extension number is calculated from these actual values, and the absent telephone number is read. In this way, by using a part of the existing abbreviated telephone number registration area as a registration area for absent telephone numbers, there is no need to provide a dedicated memory area,
The memory can be used more effectively.

When the common abbreviated telephone number registration area is used, each absent telephone number is stored successively in the order of extension number. When the individual abbreviated telephone number registration area is used, the abbreviated telephone numbers are stored in the order of extension number. Each abbreviated telephone number is stored at the same position in each established abbreviated telephone number registration area. It can be calculated by a simple address calculation formula.

After the missed telephone number of the incoming telephone is read in step 30 (see FIG. 2), it is confirmed whether or not the absence telephone number has been registered based on the contents of the read telephone number (step 30). 31). If a valid absent telephone number is not registered (step 31: N
O), a series of extension transmission processing and external line transmission processing to the absent telephone number are ended.

If a valid absent telephone number is registered (step 31: YES), the CPU 14 determines whether the external line I / F 11 corresponds to a vacant external line among the external lines L _{1 to} L _{n.
1 to} 11 _n are controlled to capture the outside line (step 32), the read out-of-absence telephone number is dialed out (step 33), and the outside line busy state is stored for various subsequent processes (step 34). ), A series of extension transmission processing and external transmission processing to the absent telephone number are terminated.

As described above, the absent telephone number is registered in correspondence with the extension number, and from the start of the extension call to the other party's answer, the extension call is terminated according to the special operation during the extension call here, The corresponding absentee phone number is read and the outside line is dialed to the absentee phone number. You can make an outgoing call to a call destination.

Next, another embodiment of the present invention will be described.
This will be described with reference to FIG. In the above description, a case has been described in which an outgoing call is made to a corresponding absent telephone number in response to a special operation during an extension call. In response to a special operation (second special operation) such as pressing a special key in a certain case or pressing a special key while capturing an outside line, and inputting an extension number, an absent telephone number registered corresponding to the extension number is read out. An outside line may be transmitted.

FIG. 4 is a flow chart showing an outside line transmission process to the absent telephone number in the idle state in the CPU 14. In the idle state, a special operation based on pressing of a special key by an arbitrary telephone (step 40) and an outside line operation based on pressing of an outside line key (step 4)
The presence or absence of 2) is repeatedly detected. In general, various operations such as an extension operation and a registration operation are detected and a process corresponding to the operation is performed, but is omitted here.

If a special operation by an arbitrary telephone is detected in step 40 (step 40: YES),
An empty outside line is captured (step 41), and the process proceeds from step 50 to a process of transmitting an absent telephone number. If an outside line operation by an arbitrary telephone is detected in step 42 (step 42: YES), the presence or absence of an incoming call is confirmed. If there is an incoming call (step 43: YES), a predetermined incoming call response process is performed. (Step 44).

On the other hand, if there is no incoming call in step 43 (step 43: NO), after capturing an available outside line (step 45), it is checked whether or not there is a special operation by the telephone. Is (Step 46: NO),
The process proceeds to a predetermined outside line transmission process (step 47). If there is a special operation in step 46 (step 4
6: YES), the process proceeds from step 50 to the transmission process of the absent telephone number.

In the transmission process of the absent telephone number, first, an extension number operation (step 50) by pressing a dial key from the telephone on which the special operation has been performed, or a call interruption (step 56) by on-hook operation of the telephone is detected. Until the extension number is entered. If the extension number operation is detected (step 50: YES), the extension number is confirmed (step 51), and the absent telephone number corresponding to the extension number is read from the memory 15 in the same manner as described above (step 50). 52) The presence or absence of the absence telephone number is confirmed based on the contents of the read telephone number (step 53).

If a valid absent telephone number is not registered (step 53: NO), the outside line being captured is displayed in the same manner as in the case where the outgoing call is detected in step 56 (step 56: YES). It is released (step 57), and the series of absent telephone number transmission processing is terminated. If a valid absent telephone number is registered (step 5
3: YES), dial out the missed telephone number read to the captured outside line (step 54), and store the outside line busy state for various subsequent processes (step 55), and perform a series of absences. The transmission process of the telephone number ends.

As described above, in response to a special operation (second special operation) such as pressing of a special key when the telephone is in an idle (normal standby) state or pressing of a special key after capturing an outside line, and input of an extension number, The abbreviated telephone number registered corresponding to the extension number is read and the outside line is dialed, so if the caller already knows the absence of the extension calling party, the normal operation follows the special operation. With the simple operation of entering the extension number of the called party, it is possible to make an outside line to the contact when you are away, and you need to look up the contact using a telephone number list etc. There is no.

In the above description, the case where the abbreviated telephone number is managed by the extension number in the memory 15 has been described as an example. However, the present invention is not limited to this, and the extension number is assigned to each extension accommodation position. If there is a correspondence table between extension numbers and extension accommodation positions so that it can be set arbitrarily, abbreviated telephone numbers and absent telephone numbers are managed according to the extension accommodation positions, and corresponding to the extension number of the called telephone The absent telephone number may be read out based on the extension accommodation position, and the same operation and effect as described above can be obtained.

Also, the case where the memory 15 for storing the control information of the CPU 14 and backing up the memory at the time of a power failure is used as the memory for storing the abbreviated telephone number and the absent telephone number has been described. Instead, a memory for backing up the memory at the time of a power failure may be provided separately from the memory 15 to store the shortened telephone number and the absent telephone number.

Further, in the simple exchange apparatus having an absence setting function for setting out of home or returning home at each telephone, when an extension is transmitted to a telephone set to be absent, the absence is notified by a tone or a voice message. It is something to be done.
Therefore, during the period from the start of the extension call to the other party's answer, in response to the special operation during the absence notification, or automatically when the absence setting is confirmed after the extension is called, the corresponding absence telephone number is read and the external line number is read out. The information may be transmitted, and the same operation and effect as described above can be obtained.

Further, a part of the abbreviated telephone number registration area provided in common or individually for each extension number includes:
Since the corresponding absent telephone numbers are stored, there is no need to provide a dedicated absent telephone number in the storage means, and the registration area is saved. Further, the storage means is a part of a common abbreviated telephone number registration area provided commonly corresponding to each extension number, and stores an absent telephone number corresponding to each extension number continuously in the order of extension number. It is something to do.

Further, the storage means is provided separately for each extension number, and is a part of each individual abbreviated telephone number registration area which has the same size and is arranged continuously in the order of extension number. The abbreviated telephone number corresponding to each extension number is stored at the same position in each individual abbreviated telephone number registration area. Therefore, the absent telephone numbers corresponding to each extension number are stored at equal intervals in the order of the extension numbers from the first absent telephone number, and the difference between the first extension number and the desired extension number and the absent telephone number And the sum of the product of the number and the storage location of the first absent telephone number, the storage location of the absent telephone number corresponding to the desired extension number can be obtained.
