2. Description of the Related Art Conventionally, as shown in FIG. 4, this type of message answering connection system responds to an incoming call to a private branch exchange 31 and sends the answered incoming call to a terminal 2 accommodated in the private branch exchange 31. 3 is used to connect to the talk device 4 and the recording device 6 for answering the message requested from the device 3.

A conventional message response connection system will be described with reference to FIGS. 4 and 5. A private branch exchange 31 used in this type of message response connection system has a line circuit 11, a speech path switch 12, an outside line trunk 13, a central processing unit 32, and a storage device 33, and the storage device 33 is a distribution service. It has a registration area 34. The line circuit 11 accommodates the terminals 2, 3, the torch device 4, the recording device 6 and the like via a line and is connected to the speech path switch 12. The speech path switch 12 is connected to a line accommodated in the line circuit 11 and an outside line trunk 13 accommodating the outside line 8. Mutual exchange connection inside the speech path switch 12 is controlled by the central processing unit 32. Has been done.
The storage device 33 stores and registers information necessary for controlling the central processing unit 32.

In the distribution service registration area 34 built in the storage device 33, as shown in FIG. 5, a code for distributing a desired service among a plurality of services for each line accommodation position is registered. Of the codes of this distribution service,
For example, the code 0 does not require the distribution service, and the other codes 1, 2 to (other than the code 1 are not shown),
Can provide various sorting services. For example, the code 1
At the time of using the Toki device 4 and the recording device 6, "I am very busy right now, I'm sorry, but please wait a while and then try again. If you have a message, beep This can be dealt with by providing a talk device 4 for a message saying "Please talk after the sound has ended" and a recording device 6 for receiving the message of the other party.

This distribution service is provided when the subscriber of the terminal 3 is busy and wants to avoid calling by an incoming call for a while.
Used for etc. When the subscriber wants to receive the distribution service, the subscriber, for example, follows the special number “16” for the distribution service with the designated number “4” for connecting the talk device 4 and the recording device 6 to the incoming call, and then “1”. Dial numbers are sent in the order of "6" and "4". By this operation, the central processing unit 32
In response to this dial number "164", the accommodation position 10 of the line to which the terminal 3 is connected in the distribution service registration area 34
The code 1 is registered in the area 01. Although not shown, the confirmation of the registration end is notified by, for example, a synthetic voice. Deletion of registration can be realized by, for example, dialing the number “169” instead of the number “164”.

[0006] When an incoming call arrives at the terminal 3 while the terminal 3 is already registered, the central processing unit 32 first searches the distribution service registration area 34 and sorts from the area of the line accommodation position 1001 of the terminal 3. Take the code 1 of the service. Since the reference numeral 1 means that the registration is being performed, the central processing unit 32 controls the communication path switch 12 by the reference numeral 1, connects the talk device 4 to the transmission path of the incoming call, and receives the reception path of the incoming call. A recording device 6 can be connected to the mobile phone to provide a message response service. As described above, in the above-mentioned distribution service, a desired message having the content according to the registration of the terminal is uniformly sent to any of the callers, that is, to the incoming call.

In the illustrated example, since the terminal 2 at the accommodation position 1000 has no distribution service registration, the code 0 is recorded in the distribution service registration area 34 corresponding to the line accommodation position 1000. There is. When the terminal 2 receives an incoming call, the central processing unit 32 performs normal connection processing.

[0008]

In the above-mentioned conventional message response connection system, when the terminal wants to avoid calling due to an incoming call, for example, by registering a predetermined code by dial operation, the terminal of the incoming call is sent. The configuration is such that a desired message is sent and a message is received from the sender. With this configuration, even if an incoming call from a specific caller such as an external call from an important customer or a urgent call from a specific dignitary, only the message response process of the same message can be performed. There is.

An object of the present invention is to provide a message answering connection system in which a private branch exchange can provide service by distinguishing an emergency or important incoming call from a specific caller from a normal incoming call.

[0010]

A message answering connection system according to the present invention is a message answering connection system in which an incoming call is distributed and connected to a predetermined line by a private branch exchange, and the private branch exchange distributes and connects the incoming call to each connection destination. The outgoing line class for distribution is defined, the outgoing line class is registered in advance by allocating the outgoing line class for each communication line, and the distribution service that connects incoming calls according to the registered outgoing line class is effective. / A distribution service registration area for registering invalidity for each communication line is provided, and when there is an incoming call to the communication line registered in the distribution service registration area, based on the communication line of the originator of the incoming call. The originating line class registered in the area of the originating communication line is retrieved from the originating line class registration area, and the incoming call is placed on the destination line defined in the retrieved originating line class. And continue to. Further, for an external line connected to another exchange, a predetermined outgoing line class is assigned as the outgoing line communication line and registered in the outgoing line class registration area.

Further, as another means, for the outside line connecting the exchanges, a call destination signal is included, and the call setting signal for requesting the setting of the call includes the calling line class. When an incoming call is received from, the calling line class is read from the call setting signal included in the incoming call,
The incoming call is connected to the connection destination line defined in the read outgoing line class.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the message response connection system shown in FIG. 1, the storage device 15 of the private branch exchange 1 is provided with a calling line class registration area 17 in addition to the distribution service registration area 16.
This is different from the message response connection system shown in FIG. 4 in that the control operation of the central processing unit 14 for the originating line class registration area 17 is added.

As in the case of FIG. 4, the private branch exchange 1 includes a line circuit 11, a speech path switch 12, and an outside line trunk 1.
3 and the central processing unit 14, and the storage device 1
As described above, 5 is provided with the distribution service registration area 16 and the outgoing line class registration area 17.

The line circuit 11 accommodates the terminals 2 and 3, the torch devices 4 and 5, the recording devices 6 and 7 via a line, and is connected to the speech path switch 12. Further, the speech path switch 12 accommodates the line accommodated in the line circuit 11 and the outside line trunk 13 accommodating the outside line 8, and the exchange connection inside the speech path switch 12 is performed by the central processing unit 1.
The storage device 15 also stores and registers information necessary for controlling the central processing unit 14.

As shown in FIG. 2, the distribution service registration area 16 and the outgoing line class registration area 17 provided in the storage device 15 correspond to the urgency and importance of communication for each line accommodation position. A distribution service for allocating incoming calls according to the above, and an outgoing line class are registered.

In FIG. 2, line accommodating positions 1000, 100
Codes 0, 1, 0, 1 are registered in the distribution service registration area 16 in correspondence with 1, 1002, 1003 respectively, and codes 1, 1, 0 are registered in the outgoing line class registration area 17.
2, 2 are registered. Sorting service registration area 16
The code 0 means that the service registration is invalid, and the code 1 means that the service registration is valid. Further, reference numeral 1 in the transmission line class registration area 17 means that the first distribution service is carried out, and reference numeral 2 means that the second distribution service is carried out. The first and second distribution services will be described later.

In this example, when registering in the distribution service registration area 16, the code 0 is used to indicate that the service registration is invalid. In the registration of the code 1, the terminal (for example) 3 requesting the registration is, for example, the special number “160” for the distribution service.
This is done by operating the dial. By the above number operation, the central processing unit 14 causes the line accommodation position 10 of the line to which the terminal 3 is connected in the distribution service registration area 16.
The code 1 is stored and registered in the area 03. In this registration, instead of the special number “160”, for example, the special number “169”
It can be erased by dialing. Confirmation of these registrations and deletions can be performed with conventional equipment and procedures.

Registration to the originating line class registration area 17 and deletion of the registration are performed in advance by a predetermined operation from the maintenance console of the private branch exchange 1 or a master terminal connected to the master line.

The first distribution service indicated by reference numeral 1 in the outgoing line class registration area 17 is an outside line telephone from an important customer,
Registered for incoming calls from specific callers, such as urgent calls from specific personnel. Line accommodation position 1000
When an outside line is connected to the line and the line accommodating position 1001 is connected to, for example, the terminal of the president, the code 1 is registered in the transmission line class area as shown in FIG. In this state, the line accommodating position 10 having the calling line class of code 1
Outgoing calls from the lines 00 and 1001 can be received by any receiving terminal regardless of whether the service registration at the receiving terminal is valid or invalid.

Further, the second distribution service indicated by reference numeral 2 in the outgoing line class registration area 17 corresponds to, for example, the talk machine 5 for transmitting the same message as an ordinary answering machine and the terminals 2, 3 ,. Recording devices 6, 7, ..., Which receive the message of the other party, are provided.

An outgoing call from the terminal (for example) 2 of the line of the class 2 and the line of the line accommodating position 1002 shown in FIG. 2 is received by the terminal 3 of the valid line accommodating position 1003 for which the service is registered. In this case, the caller's terminal 2 is not connected to the callee terminal 3 using the dial number, but to the talkie device 5 corresponding to the second distribution service and the recording device 7 corresponding to the callee terminal 3. This operation procedure will be described later.

In this example, the distribution service up to the second by the reference numeral 2 has been described, but the distribution services of the third and subsequent are also provided, and a plurality of types of toke apparatus are provided depending on the type of the distribution service, and a plurality of types of distribution services are provided. Response message can be provided. Further, for a calling line class of low urgency and importance, a sorting service can be provided to eliminate the connection to the recording device only by the guidance of the talk device.

Next, the main operation of the central processing unit 14 will be described with reference to FIG. 3 together with FIG. 1 and FIG. First, when the central processing unit 14 of the private branch exchange 1 receives an incoming call (procedure 21), it identifies the line accommodation positions of the originating line and the incoming line (procedure 22). Next, the central processing unit 14 searches the distribution service registration area 16 of the storage device 15 and investigates whether or not the distribution service is registered (procedure 23).

If YES in step 23 and the code is 1 in the distribution service registration area 16, the calling line class is read from the line accommodation position of the calling line identified in step 22 (step 24).
You. For example, when a call is received from an outside line and this outside line is connected to the line accommodating position 1000, the read outgoing line class is code 1 (YES in step 25), and the central processing unit 14 performs a normal incoming call connection operation ( Perform step 26),
Connect the outgoing line to the called terminal requested by the sender.
On the other hand, if the procedure 23 is NO and the distribution service registration area 16 is 0, the normal incoming call connection of the procedure 26 is performed.

Further, as described above, for example, when a call is made from the terminal 2 connected to the line accommodation position 1002, the read call line class is the code 2 (N in step 25).
O). When this incoming call arrives at the terminal 3 connected to the line accommodation position 1003, the central processing unit 14
Controls the speech path switch 12 to provide the message reply service of reference numeral 2. As a result, the source terminal 2
A talk device 5 corresponding to the class code 2 of the outgoing line is connected to the transmission path to the, and a recording device 7 corresponding to the destination terminal 3 is connected to the receiving path to provide a message response service to the incoming call. provide. As a result, the terminal 3 can listen to the recording of the message by the sorting service from the recording device 7 by the equipment and the predetermined dial operation by the well-known technique.

The torch device and the recording device described with reference to FIG. 1 are accommodated and connected in the line circuit of the private branch exchange,
It is connected to the central processing unit via a line circuit,
Similar to the trunk, it may be directly connected to the communication path switch and directly connected to the central processing unit. Further, the talkie device is divided into blocks for each message, and the recording device is divided into blocks for each terminal, but it is possible to collectively install the devices by performing address control on the disk.

Further, in the connection between the exchanges using the outside line, the transmission line class of this kind is encoded by the common line signaling method into the message format applied to the call setting of the basic call control sequence defined by ISDN. By including it, the same function as the above can be exhibited. In this case, for the outgoing call to the outside line, the central processing unit sends the call setting message including the outgoing line class of the outgoing line to a predetermined portion of the message format. On the other hand, for an incoming call from an outside line, the central processing unit takes out the calling line class from a predetermined place of the call setting message and uses it for connection control instead of the calling line class registration area of the storage device.

[0029]

As described above, according to the present invention, the private branch exchange determines the transmission line class for distribution for each connection destination to which the incoming call is distributed and connected, and allocates this transmission line class for each communication line. It is equipped with an outgoing line class registration area that is registered in advance and a distribution service registration area that registers the application of the distribution service in which the communication line is distributed and connected according to the outgoing line class, and calls are received on the communication line registered in the distribution service registration area. When there is a call, the originating line class registered in the area of the originating communication line based on the originating communication line of the incoming call is retrieved from the originating line class registration area and the connection destination specified in the retrieved originating line class You have an incoming call connected to your line.

According to this configuration, when the terminal wants to avoid calling due to an incoming call, by registering the application of the distribution service by dial operation, it is possible to distinguish the calling line class registered as the originator of the incoming call. Allowing connection for incoming calls from specific callers, such as external calls from important customers, urgent calls from key persons, or
A separate message enables detailed message response processing.
