Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private automatic branch exchange which enables a call forwarding service for automatically forwarding an incoming call to an extension to a registration destination.

[0002]

2. Description of the Related Art A conventional example will be described below with reference to the drawings. FIG. 5 shows a system configuration diagram of a conventional private automatic exchange, FIG. 6 shows a data structure stored in a storage means of the private automatic exchange, and FIG. 7 shows processing when registering and canceling an absent transfer destination of the private automatic exchange. FIG. 8 shows a flow, and FIG. 8 shows a processing flow at the time of calling the extension of the private automatic branch exchange.

As shown in FIG. 5, a conventional private automatic branch exchange has an interface between extension line circuit means 4, 5 and 6 for controlling interfaces with extension lines (extension telephones) 1, 2 and 3 and station lines 7 and 8. The station line circuit means 9 and 10 for controlling the extension line means, the extension line circuit means 4, 5 and 6 and the station line circuit means 9 and 10 to mutually connect arbitrary station lines 7 and 8 and extension lines 1, 2 and 3. And a storage means 12 for storing the absent transfer destinations registered from the extensions 1, 2, 3 and these extension circuit means 4, 5, 6 and the station line circuit. It comprises means 9 and 10, a communication path means 11, and a control means 13 for controlling the storage means 12.

As shown in FIG. 6, the storage means 12 indicates whether or not the extensions 1, 2 and 3 are registering the absent transfer destination.
Stored are missed transfer registration flags 20, 22, and 24 that are true during registration, and missed transfer destination data 21, 23, and 25 that are valid only when the missed transfer registration flags 20, 22, and 24 are true. ..

The operation and processing steps in the conventional private automatic branch exchange constructed as described above will be described with reference to FIGS. First, the processing at the time of registration (step 30) and cancellation (step 33) of the absence transfer destination will be described with reference to FIGS. 7 and 5 and 6.

The description will be made assuming that the first extension (extension telephone) 1 registers and cancels call forwarding. First
When the control means 13 recognizes the absent transfer registration operation from the extension 1 through the extension circuit means 4, the absent transfer registration flag 20 corresponding to the first extension 1 is set to true (step 31),
Store the transfer destination in the absent transfer destination data 21 (step 3)
2). At the time of cancellation, the same processing as at the time of registration is performed. When the control means 13 recognizes the operation for canceling the absence transfer from the first extension 1 via the extension circuit means 4, the absence transfer registration flag 20 corresponding to the first extension 1 is set to false (step 34) and the absence is set. The transfer destination data 21 is cleared (step 35).

Next, the processing (step 40) at the time of calling from extension to extension will be described with reference to FIGS. Now, it is assumed that a call operation is made to the nth extension 3 by the first extension 1 (step 41). The control means 13 first causes the nth extension 3 to receive an incoming call, and checks whether the nth extension 3 answers the incoming call within the set number of times (step 42). If you respond within the set number of times, do nothing.
If it does not answer the incoming call more than the set number of times, it is judged as absent, and it is checked by referring to the absent-transfer registration flag 24 whether the nth extension 3 which is the called extension is registering the absent-transfer destination. Yes (step 43). If the absent transfer registration flag 24 is true, the transfer destination stored in the absent transfer destination data 25 is called (step 44). If the absence transfer registration flag 24 is false, nothing is done.

[0008]

However, in the private automatic branch exchange having the above-mentioned conventional structure, only one transfer destination can be set and the originator cannot be specified. Therefore, all incoming calls are transferred to the same extension. It was Therefore, there is a problem that an incoming call from a great person such as a VIP is transferred to the same forwarding destination as an incoming call from a general extension.

The present invention solves the above-mentioned conventional problems, and provides a private automatic branch exchange capable of forwarding an incoming call from a preset extension to an incoming call when absent. It is intended to be provided.

[0010]

In order to solve the above-mentioned problems, the present invention provides an extension circuit means for controlling an interface with an extension telephone, a station line circuit means for controlling an interface with a station line, and the extension circuit. Means and station line circuit means to connect any station line and extension to each other to provide a voice path, and an absent transfer destination for an absent transfer of an extension telephone and an absent transfer for which a sender can be designated. Storage means for storing a sender and an absent transfer destination, and the extension circuit means,
By controlling the station line communication means and the storage means, when an incoming call from an absence is received from an originator for absence transfer set in the storage means, it is transferred to the transfer destination set in the storage means. And a control means for controlling.

[0011]

With the above structure, when the extension is called when the user is absent, the control means compares the data of the sender for the designated-absent transfer with the sender with the sender to determine the absence transfer destination corresponding to the sender. Then, the transfer process is performed to the extension indicated by this absent transfer destination. As a result, the transfer destination can be changed according to the sender, and the transfer destination can be set according to the sender.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In addition, the same reference numerals are given to those having the same functions as the conventional ones, and the description thereof will be omitted.

FIG. 2 shows a system configuration diagram of a private automatic branch exchange according to an embodiment of the present invention, FIG. 1 shows a data structure stored in a storage means, and FIG. 3 shows registration and cancellation of a destination-specified absent transfer destination. FIG. 4 shows a processing flow when the extension is called.

As shown in FIG. 2, the system of the private branch exchange has the same structure as that of the conventional system, but the storage means 14 is used for the absent transfer of the extension telephones stored in the conventional system, as will be described later. In addition to the absent transfer destination, the sender and the absent transfer destination for the absent transfer (hereinafter abbreviated as the sender-specified absent transfer) that can specify the sender are stored. Then, together with the storage means 14, the extension circuit means 4, 5, 6,
The station line circuit means 9 and 10 are controlled by the control means 15.

As shown in FIG. 1, the storage means 14 indicates whether or not the extensions (extension telephones) 1, 2 and 3 are registering the absent transfer destination, and the absent transfer registration becomes true during the registration. Flag 2
0, 22, 24 and absent transfer destination data 21, 23, 25 which are valid only when the absent transfer registration flags 20, 22, 24 are true are stored as in the conventional case.

Further, the storage means 14 stores extensions 1, 2, 3
Indicates whether or not is registering a call forwarding destination
Registered call forwarding flag 50, 5 that becomes true during registration
3, 56, source data 51, 54, 57 of source-specified unattended transfer that is valid only when the source-specified unattended transfer registration flag 50, 53, 56 is true, and source-specified unattended transfer registration flag 5
Stored is the sender-specified absent transfer destination data 52, 55, and 58, which is valid only when 0, 53, and 56 are true.

3 and 4 show the processing steps of the operation and control of the private automatic branch exchange of the present embodiment configured as described above.
It will be explained based on. First, the processing at the time of registering (step 60) and canceling (step 64) the destination-designated absent transfer destination will be described with reference to FIGS. 3 and 1 and 2. Here, description will be made assuming that the call with designated source is absent and registered with the first extension 1 and that the registration is the first registration with the first extension 1.

When the control means 15 recognizes the originator-specified absent transfer registration operation from the first extension 1 through the extension circuit means 4, it is the first registration operation, and therefore corresponds to the first extension 1. The # 1 caller-specified absent transfer registration flag 50 is set to true (step 61), and the caller is set as caller data 51 (step 61).
62), and the transfer destination is stored in the designated absentee transfer destination 52 (step 63).

At the time of cancellation, the same processing as at the time of registration is performed. First
When the control means 15 recognizes, via the extension circuit means 4, the operation of canceling the transfer of the caller designated by the extension 1 from the extension 1, the flag 50 of the designated transfer of the transmission source corresponding to the first extension 1 is set to false (step 65). ), Clear the sender data 51 (step
66), and also clears the designated-absence transfer destination data 52 (step 67).

The above-mentioned processing at the time of registering and canceling the source-specified absent transfer destination has been described for the case where data is set in the data area related to the source-specified absent transfer of # 1 of the first extension 1. The same applies to the case where data is set in the data areas related to the transmission by specifying a source other than the extensions 2, 3 and # 1.

Next, the processing (step 70) at the time of making a call from extension to extension will be described with reference to FIGS. 4 and 1 and 2. Now, it is assumed that a call operation is made to the nth extension 3 by the first extension 1 (step 71). The control means 15 first causes the nth extension 3 to receive an incoming call. It is checked whether the nth extension 3 answers the incoming call within the set number of times (step 72). If you respond within the set number of times, do nothing.

When the incoming call is not answered more than the set number of times, it is judged as absent, and it is judged whether or not the nth extension 3 which is the called extension is registering the caller designated absent transfer destination. The check is made by referring to # 1 to # 1 designated absent transfer registration flag 56 in 3 (step 73). This # 1
If any of the designated-to-originating-absence transfer registration flag 56 of # 1 to # 1 is true, the originating data 57 of # 1 to # 1 is referred to, and it corresponds to the first extension 1 which is the originator here. It is checked whether the data is in the source data 57 (step 7).
Four). If there is data corresponding to the first extension 1 of the caller, the call is transferred to the extension indicated by the caller-specified absent transfer destination data 57 (steps 75 and 76).

If the # 1 to # 1 source designated absent registration flag 51 is false, or if the # 1 to # 1 source data 57 does not include data corresponding to the first extension 1 as the source. , Like the conventional call forwarding process, the nth
It is checked whether or not extension 3 is registering the absent transfer destination by referring to the absent transfer registration flag 24 (step 7).
7). If the absent transfer registration flag 24 is true, the transfer destination stored in the absent transfer destination data 25 is called (step
78). If the absence transfer registration flag 24 is false, nothing is done.

As a result, the transfer destination can be changed according to the sender, and the transfer destination can be set according to the job rank of the sender.

[0025]

As described above, according to the present invention, a storage means for storing an absent transfer destination for an absent transfer of an extension telephone and an absent transfer source and an absent transfer destination for which a sender can be designated, and By controlling the extension circuit means, the office line communication path means, and the storage means, the incoming call from the absence is set by the storage means if the incoming call is from the sender for the absence transfer set by the storage means. By providing a control means to transfer to the transfer destination, it is possible to change the absent transfer destination by specifying the sender with the absence transfer function, and it is very convenient to set the transfer destination according to the job rank of the sender. It becomes possible to provide high-quality services.
