A registration operation for designating both or one of the internal call transfer destination and the external call transfer destination is performed, and it is shown that the telephone exchange apparatus 1 performs the incoming call processing to the key telephone 2-1 in accordance with the specification. I have.

In FIG. 2, in the extension call transfer termination processing, when the incoming call is an extension call (incoming call from the key telephone 2-4 in the illustrated example), the call is transferred to the key telephone 2-2. In addition, the incoming call is an outside line call (in the illustrated example, outside line 3).
), The call is forwarded to the key telephone set 2-3.

As a precautionary note, when a registration operation for specifying one of the extension call transfer destination and the external call transfer destination is performed, the telephone exchange apparatus 1 sets the call received by the key telephone 2-1 to a call. On the other hand, one of the unspecified calls out of the extension call and the outside call is received by the key telephone 2-1 and the other specified call is transmitted to another key telephone (the key telephone 2-2 or the key telephone 2-3). Call to be forwarded.

Now, an extension call refers to a call for an extension call from one key telephone set to another key telephone set, and an external line call refers to a call from an external line 3 to a certain key telephone set. Call for outside line communication.

First, the transfer destination registration process will be described with reference to FIGS. 1 and 2 along with FIG. This transfer destination registration process is performed by the user of the key telephone 2-1.
1 to any one of access codes "50" to "55"
This is done by entering one. As can be understood from the above description of the access code, designation of either or both of the internal call transfer destination and the external call transfer destination and the designation of the transfer conditions (absence transfer, unanswered transfer, busy transfer) can be performed simultaneously. It has become.

The access code from the key telephone 2-1 is input to the access code analyzing means 41 via the key telephone interface 11, and the contents thereof are analyzed (step S1), and the access code is changed to the above access code "50". It is determined whether or not any of .about. "55" is satisfied (step S2).

If the access code input from the key telephone 2-1 does not correspond to any of the above access codes "50" to "55" (step S2; No), the access code analyzing means 41 determines Control unit 14
Report to The control unit 14 processes the access code in a conventional manner.

On the other hand, the access code analyzing means 41 determines that the access code input from the key telephone 2-1 corresponds to any one of the access codes "50" to "55" (step S2; Yes). Then, it is determined whether the registration request is for both an internal call and an external call (step S3). If the access code is a registration request for both an internal call and an external call (step S3; Yes), the access code analysis unit 41 reports this to the transfer destination registration unit 42. The access codes indicating the registration request of both transfer destinations are “50”, “52”, and “54”.
It is.

The transfer destination registration means 42 sequentially displays, on the display of the key telephone 2-1 via the key telephone interface 11, an instruction for inputting a transfer destination telephone number for an internal call and a transfer destination telephone number for an external call. The telephone number is obtained in each case, and the transfer destination telephone number and the transfer condition are registered in the data section 13 in association with the telephone number of the key telephone 2-1 (step S4). In the example of FIG. 2, the telephone number of the key telephone 2-2 is registered as a transfer destination for an internal call, and the telephone number of the key telephone 2-3 is registered as a transfer destination for an external call.

The operation for registering both transfer destinations from the key telephone set 2-1 is specifically as follows, for example. This example is the case of call forwarding. (A) Lift the handset and hear the extension dial tone. (B) Access code "5
Dial "0". (C) What is the extension call transfer destination on the display? Is displayed, the telephone number of the key telephone 2-2 is dialed. (D) Next, what is the external call transfer destination on the display? Is displayed, the telephone number of the key telephone 2-3 is input. (E) Hear the confirmation tone and hang up the handset.

In step S3, if the access code is a registration request for either an internal call or an external call (step S3; No), the access code analyzing means 41 transmits a notification to that effect. This is reported to the destination registration means 42. The access codes indicating one of these registration requests are “51”, “53”, and “55”.

The transfer destination registering means 42 displays an instruction for inputting a transfer destination telephone number for either an internal call or an external call on the display of the key telephone 2-1 via the key telephone interface 11, and displays the telephone number. And the data section 13
The transfer destination telephone number and the transfer conditions are entered into the key telephone 2-1.
(Step S5). In the example of FIG. 2, the key telephone 2 is used as the extension call transfer destination.
Register the telephone number of -2, and do not register the external call transfer destination. Alternatively, the key telephone 2-3 can be used as a transfer destination for external calls.
Is registered, and the extension call transfer destination is not registered.

The operation of registering one of the transfer destinations from the key telephone 2-1 is specifically as follows, for example. In this example, call forwarding is set only for an outside line call. (A) Lift the handset and hear the extension dial tone. (B) Dial the access code "51". (C) The extension call transfer destination: 1? or external call transfer destination: 0? Is displayed, dial "0". (D) Next, what is the external call transfer destination on the display? Is displayed, the telephone number of the key telephone 2-3 is input. (E) Hear the confirmation tone and hang up the handset.

Next, the transfer incoming call processing will be described with reference to FIGS. When the key telephone 2-4 makes an extension call to the key telephone 2-1, the control unit 14 of the telephone exchange 1 detects the incoming call (step S10).
The control unit 14 searches the data unit 13 and checks whether or not there is a transfer destination setting in the key telephone 2-1 which is the destination (step S11).

When there is no transfer destination set in the key telephone set 2-1 as the destination, the control unit 14 causes the key telephone set 2-1 to receive the incoming call as usual (step S1).
3). On the other hand, the control unit 14 determines that there is a transfer destination setting in the key telephone 2-1 which is the destination (step S11: Y
es) reports this to the transfer destination determining means 43.

The transfer destination determining means 43 determines whether the incoming call is an internal call or an external call (step S1).
2). If the incoming call is an extension call,
The transfer destination telephone number for the extension call and the transfer conditions are acquired from the data unit 13 and passed to the control unit 14 (step S14). Further, when the incoming call is an outside line call,
The transfer destination telephone number and the transfer condition for the external call are acquired from the data unit 13 and passed to the control unit 14 (step S15).

The control unit 14 transfers the incoming call to the key telephone having the obtained transfer destination telephone number in accordance with the transfer conditions and causes the key telephone to receive the call (step S16). As a result, it is possible to assign an appropriate responder to an incoming call from the outside or an incoming call from inside the telephone exchange apparatus 1.

For example, the user of the key telephone 2-1 is
When you register for Call Forwarding when you go out, register the telephone number of your mobile terminal (extension telephone number) or the telephone number of a fixed telephone (external telephone number) such as a conference room of the company you are going to call for external calls. Key telephone 2-2 for calling
Register the telephone number (extension telephone number).

Then, the extension telephone from the person inside the system is made to correspond to the other person in the department, and the person himself / herself responds to the customer's telephone call from the outside line by using the portable terminal owned by him or the conference room of the company where he / she is going. It can be handled from a fixed telephone such as a telephone.

In the case of unanswered transfer or busy transfer, a customer's telephone call coming from an outside line is forwarded to an expert to have it dealt with, and an extension telephone from a person inside the system is forwarded to a lower class person in the department. It will be possible to receive correspondence.

When either one of an internal call and an external call is registered as a transfer destination, for example, if only an internal call is registered, the telephone number of a customer who calls from an external line when the person is at the table is registered. Can be handled by the person himself / herself, but can be prevented from receiving an extension call from a person inside the system.

In the above description, an extension call refers to a call for an extension call from one key telephone to another key telephone, and an outside call refers to a call from an external line 3 to a certain key telephone. It refers to a call for a called outside line. However, the definition of the extension call and the extension call is not limited to this, and a configuration that can be freely changed may be adopted.

For example, a system is provided with a flag for distinguishing between a call handled as an extension call and a call handled as an external call, and the transfer destination determining means 43 refers to the flag for each incoming call and determines whether the call is an extension call or an external call. That's what they do.

In this manner, for example, as domestic specifications, the local line (external line 3) and the dedicated line 4 are treated as external calls, and outgoing calls from inside the system are treated as internal calls. Only the central office line (external line 3) is treated as an external call, and calls from inside the system and the dedicated line 4 are treated as internal calls.

Further, in the present embodiment, an access code for canceling the registration items in the data section 13 is also prepared, and the registration items can be changed, modified, or deleted.

Furthermore, in the present embodiment, the telephone exchange system of the key telephone apparatus has been described for the sake of convenience of explanation, but the present invention is not limited to this and can be similarly applied to the telephone exchange system of the private branch exchange.

[0050]

As described above, according to the present invention,
Since the transfer destination can be individually specified for both the extension call and the external call, and the transfer destination can be specified for either the extension call or the external call, the transfer destination can be divided according to the type of the incoming call. Therefore, according to the present invention, it is possible to appropriately cope with the incoming call of the extension call and the incoming call of the outside call.
