[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange.

[0002]

2. Description of the Related Art Conventionally, some telephone exchanges have a telephone transfer function for automatically transferring an incoming call to a designated transfer destination by presetting.

The structure of a conventional telephone exchange having a telephone transfer function will be described below. FIG. 4 is a block diagram showing the configuration of a conventional telephone exchange. In FIG. 4, the telephone exchange 1 is roughly divided into an external line interface unit 3 that is connected to an external line 2 to open and close a telephone line, and an internal line interface unit 5 that is connected to an extension line 4 to open and close a telephone line. It is composed of three departments, a phone transfer unit 6 having a phone transfer function for transferring an incoming call to a designated transfer destination, and a control unit 7 having overall control of each department. Extension 4
An extension telephone section 8 is connected to the extension telephone section 8
Although the number of extension telephones corresponding to the number of extension numbers that can be set is connectable to, the number of extension numbers that can be set is 5 and the extension telephones are set to 8a for simplification of description.
5 units of ~ 8e. In addition, extension numbers "801" to "805" correspond to the extension telephones 8a to 8e in a one-to-one correspondence. The transfer setting storage unit 6a of the telephone transfer unit 6 is provided with areas that correspond to the extension telephones 8a to 8e on a one-to-one basis, and a transfer instruction is issued to each of these areas. The transfer function setting flag indicating "" is set, and a telephone number (regardless of extension or outside line) is registered as an example of telephone information of the transfer destination.

First, the operation at the time of setting the telephone transfer function will be described with reference to the flowchart showing the operation at the time of setting the telephone transfer function of the conventional telephone exchange shown in FIG. In FIG. 5, to transfer an incoming call to the extension telephone 8a to the extension telephone 8b, first, the extension telephone 8a is off-hook (step 1), and a transfer setting special number, for example, "# 01" is dialed (step 2). . Subsequently, the extension number "802" as the telephone information of the extension telephone 8b of the transfer destination is dialed (step 3), and finally the transfer setting confirmation special number, for example, "# 02".
Dial (step 4). Then, the telephone transfer unit 6
The transfer function setting flag indicating that a transfer command is issued is set in the area of the extension telephone set 8a of the transfer setting storage unit 6a, and the extension number of the extension telephone set 8b as the transfer destination is registered (step 5).

Next, the operation during the telephone transfer will be described with reference to the flowchart showing the operation during the telephone transfer in the conventional telephone exchange shown in FIG. In FIG. 6, when a ring signal is input from the outside line 2 to the telephone exchange 1, the control unit 7 controls the outside line interface unit 3 to close the outside line 2 and to use the extension line interface to call the extension telephone 8a to be dialed. The extension 5 is closed by controlling the part 5. When making a call between the extension telephone units 8 from each other, the extension 4 to the telephone exchange 1
When the herring signal is input, the control unit 7 controls the extension interface unit 5 to call the extension telephone 8a to be dialed and closes the extension 4. The extension telephone 8a is called as described above (step 6). Next, the control unit 7 controls the telephone transfer unit 6 to check the area of the extension telephone set 8a of the transfer setting storage unit 6a, and whether the transfer function setting flag indicating that a transfer command has been issued is set. It is determined whether or not (step 7). If the transfer function setting flag is not set, the transfer cannot be performed, and the extension telephone 8a that has been called up is called (step 8). If the transfer function setting flag has been set, the extension number "802" of the extension telephone 8b that is the transfer destination in order to enter the transfer state.
And the extension telephone set 8b having the read extension number
The extension interface unit 5 is controlled to transfer the call (step 9).

[0006]

However, in the configuration of the conventional telephone exchange as described above, once the transfer function is set, all the incoming calls to the extension telephone 8a are transferred regardless of the importance of the message. It was transferred to the extension telephone 8b. For this reason, even during an important meeting, the extension telephone 8b of the transfer destination is unavoidable, and in the case of a less important message, it may belong to the category of a nuisance call.

It is an object of the present invention to solve the above problems and to provide a telephone exchange that transfers only highly important telephones to a designated forwarding destination by selecting a calling party.

[0008]

In order to achieve the above object, the present invention provides an external line interface unit for connecting to an external line to open / close a telephone line, an internal line interface unit for connecting to an internal line to open / close a telephone line, in advance. By setting the call transfer function to transfer the incoming call to the specified transfer destination, and the control unit responsible for overall control of each department, the incoming call is specified. When transferring to the transfer destination, it is determined whether or not the caller's phone information is registered in the phone transfer unit, and only when the caller's phone information is already registered, the call is transferred to the specified transfer destination.

[0009]

With this configuration, the caller can be selected according to whether or not the telephone information of the caller is registered, and only the telephones with high importance can be transferred to the designated transfer destination.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. The same parts as those in the conventional example are designated by the same reference numerals.

FIG. 1 is a block diagram showing the configuration of a telephone exchange according to an embodiment of the present invention. In FIG. 1, the telephone exchange 9 is roughly divided into an external line interface unit 3 connected to an external line 2 to open / close a telephone line, an internal line interface unit 5 connected to an extension line 4 to open / close a telephone line. It is composed of three departments, a phone transfer unit 10 having a phone transfer function for transferring an incoming call to a designated transfer destination, and a control unit 7 having overall control of each department. An extension telephone unit 8 is connected to the extension 4 and a number of extension telephones corresponding to the number of extension numbers that can be set can be connected to the extension telephone unit 8, but here, for simplification of description, The number of extension numbers that can be set to 5 is the same as the conventional example.
Let us assume that there are five extension telephones 8a to 8e. Also,
The extension number "801" is assigned to each of the extension telephones 8a to 8e.
"805" has a one-to-one correspondence. Telephone transfer unit 10
Is a transfer setting storage unit 10a, a transfer validator storage unit 10b,
Specific caller storage unit 10c, and caller storage unit 10d
4 departments, and each department is provided with an area corresponding to each of the extension telephones 8a to 8e on a one-to-one basis. For each of these areas, a transfer function setting flag that indicates that a transfer command has been issued, and a telephone number as an example of telephone information of the caller or the transfer destination (extension or outside line is not required) To register.

First, an operation example when setting the telephone transfer function will be described with reference to a flow chart showing an operation when setting the telephone transfer function of the telephone exchange in the embodiment of the present invention shown in FIG.

(Operation Example 1) In FIG. 2, first, the extension telephone 8a is taken off-hook (step 10), and the transfer setting special number "# 01" is dialed (step 11). Then, the extension number "802" of the extension telephone 8b of the transfer destination is dialed (step 12). Next, depending on whether or not all the incoming calls to the extension telephone set 8a are transferred to the extension telephone set 8b, the process is branched (step 13).

When all incoming calls to the extension telephone set 8a are transferred to the extension telephone set 8b, the transfer setting confirmation special number "# 0" is finally given.
When you dial "2" (step 14), the telephone transfer unit 1
A transfer function setting flag indicating that a transfer command is issued and an extension number of the extension telephone 8b as the transfer destination are registered in the area of the extension telephone 8a of the transfer setting storage unit 10a of 0 (step 15). .

If an incoming call to the extension telephone set 8a is to be transferred to the extension telephone set 8b only from a specific caller (whether extension line or outside line), for example, the extension telephone set 8c,
Extension "803" of extension telephone 8c that is a transfer validator
Dial (step 16). Finally, the transfer setting confirmation special number "# 02" is dialed (step 17). Then, first, the extension number "802" of the extension telephone 8b, which is the transfer destination for which the transfer is valid, is registered in the area of the extension telephone 8a of the transfer validator storage unit 10b (step 18), and then the memory for each specific caller is stored. The extension number "80" of the extension telephone 8c, which is a specific caller, to the area of the extension telephone 8a of the section 10c.
3 ”is registered (step 19). Then, a transfer function setting flag indicating that a transfer command is issued is set in the area of the extension telephone set 8a of the transfer setting storage unit 10a (step 20).

(Operation Example 2) By the way, it is possible to set a plurality of specific callers. A call to the extension telephone set 8a is transferred to the extension telephone set 8b only when the caller is a specific caller (whether extension line or outside line), for example, the extension telephone set 8c, and similarly, only when the extension telephone set 8e is set to the extension telephone set 8d. When it is desired to transfer the data, the processing of the block enclosed by the broken line is changed only when it is transferred from the extension telephone 8e to the extension telephone 8d, and the same procedure is repeated and repeated. Then, the extension number "804" of the extension telephone 8d, which is the transfer destination for which the transfer is valid, is additionally registered in the area of the extension telephone 8a of the transfer validator storage unit 10b (step 18), and the specific caller-specific storage unit 10c is stored. The extension number "805" of the extension telephone 8e, which is a specific caller, is additionally registered in the area of the extension telephone 8a (step 19).

Next, an example of the operation during the telephone transfer will be described with reference to the flow chart showing the operation during the telephone transfer of the telephone exchange in the embodiment of the present invention in FIG.

(Operation Example 1) In FIG. 3, when a ring signal is input from the external line 2 to the telephone exchange 9, the control unit 7 controls the external line interface unit 3 to close the external line 2 and the extension line of the dial destination. The extension interface unit 5 is controlled to call the telephone 8a and the extension 4 is closed. When making a call between the extension telephone units 8, when a ring signal is input from the extension 4 to the telephone exchange 9, the control unit 7 controls the extension interface unit 5 to call the extension telephone 8a to be dialed. Then, extension 4 is closed. The extension telephone 8a is called as described above (step 21). Next, the control unit 7 controls the telephone transfer unit 10, and the telephone information of the calling party (whether internal or external) detected in the area of the extension telephone 8a of the caller storage unit 10d, for example, the extension telephone 8 is used.
The extension number "803" of c is registered (step 22).
This prepares the caller for selection.

Next, the area of the extension telephone set 8a in the transfer setting storage section 10a is checked to determine whether or not a transfer function setting flag indicating that a transfer command has been issued is set (step 23). . If the transfer function setting flag is not set, the transfer cannot be performed, and the extension telephone 8a that has been called up is called (step 24).

If the transfer function setting flag has been set,
In order to enter the transfer mode, it is first determined whether or not the transfer destination telephone number is registered in the same extension telephone area 8a of the transfer setting storage unit 10a (step 25). If the telephone number of the transfer destination is already registered, the registered telephone number, for example, the extension number "802" is read out, and the extension interface unit 5 is controlled to call the extension telephone 8b of the transfer destination (step 26).

If the transfer destination telephone number is not registered, since the transfer function setting flag is set, the transfer destination whose transfer is valid is always registered in the area of the extension telephone 8a of the transfer validator storage unit 10b. Therefore, the registered telephone number, for example, the extension number “802” is read (step 2
7). Next, the extension telephone 8 of the storage unit 10c for each specific caller
The telephone number registered in the area "a" is read out, and it is checked in step 22 with the extension number "803" of the extension telephone 8c registered in the area of the extension telephone 8a of the caller storage unit 10d to determine whether they match. A judgment is made (step 28).

If they match, that is, the specific calling party storage unit 1
If the telephone number registered in the area of the extension telephone set 8a of 0c is the extension number “803”, the extension interface unit 5 is controlled to read the extension number “8” in step 27.
02 "and the extension telephone 8b is called (step 29). If they do not match, the transfer cannot be performed, so the transfer is stopped and the process proceeds to step 24, where the extension telephone 8a called as it is is called.

(Example 2 of operation) By the way, an incoming call to the extension telephone 8a is transferred to the extension telephone 8b only from a specific caller (whether extension or outside), for example, the extension telephone 8c. Extension telephone 8 only from telephone 8e
When the user wants to transfer the call to d, that is, when a plurality of specific callers are set, in addition to the operation described in (Operation example 1), the process of the block enclosed by the broken line is performed only from the extension telephone 8e. When it is desired to transfer to the extension telephone 8d, the correspondence is changed and the same procedure is repeated.

In the above description, only the telephone exchange has been mentioned, but in FIG.
If it is considered that the telephone exchange 9 and the extension telephone 8a constitute a master unit, and each of the extension telephones 8b to 8e constitutes a slave unit, it can be applied to a telephone device.
