Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a station line termination connection device, and more particularly to a station line termination connection device in a private branch exchange connected to a public network (analog / ISDN).

[0001]

2. Description of the Related Art Conventionally, as an incoming call connection method in a private branch exchange (hereinafter sometimes abbreviated as PBX),
A method in which the switcher responds at the exchange and manually connects to the destination terminal (extension) desired by the caller, and the caller's desired line (station line group) is designated by the automatic voice response service. A method of connecting an extension to correspond to an office line, a method of connecting to an extension corresponding to a dial-in number,
There is also a method of connecting an extension corresponding to a caller identifier (hereinafter, may be abbreviated as caller ID or caller ID).

[0002]

In the above-mentioned conventional connection method, since the calling party cannot be known at the time of receiving a call, only a reply can be made and then the call can be transferred to a target terminal. However, there was a problem in the work efficiency due to the maintenance of calls and manual / automatic telephone transfer, and the serviceability to callers.

Further, in the connection method, the caller is directly connected to the intended destination of the extension, but if the caller is absent, the call must be manually transferred in the same manner as the above method.

Further, even in the case of the call receiving method corresponding to the caller identifier such as the connection method, the call receiving terminal is determined by the caller identifier. Could not handle incoming calls.

Therefore, an object of the present invention is to provide a station line incoming connection system for connecting to an optimum terminal corresponding to a caller identifier received from a public network.

It is another object of the present invention to improve the serviceability of a callee identifier-corresponding callee registration method such as automatic callee registration for an unregistered caller identifier or simple setting from a terminal.

[0007]

Means for Solving the Problems [1] A station line incoming / outgoing connection device according to the present invention for achieving the above object is a caller for each station line, station line group, dial-in number or bearer service. The destination automatic routing table in which the relationship between the identifier and the destination terminal number is registered, and one or more arbitrary destinations by referring to the destination automatic routing table based on the caller identifier received from the public network. It is premised that an incoming call control unit for searching for a terminal number and preferentially receiving an incoming call at the terminal of the called terminal number is provided.

That is, as conceptually shown in FIG.
A destination automatic routing table is prepared in the station line receiving / connecting device C that constitutes the BX, and a caller identifier and a destination are provided in the destination automatic routing table for each station line, station line group, or dial-in number and for each bearer service. The relationship with the terminal number is registered in advance.

Then, the incoming call control unit in the station line incoming call connection device C which has received the caller identifier (calling ID) based on the connection request from the caller A via the public network B, refers to the incoming call destination automatic routing table. By doing so, the number of the destination terminal (extension D) corresponding to the caller identifier is received.

In this case, since the destination automatic routing table registers the relationship between the caller identifier and the destination terminal number for each station line, station line group, dial-in number, or bearer service (ISDN, etc.), It is possible to search for an arbitrary terminal number (one or more) in the prepared desired destination automatic routing table and preferentially make an incoming call to any terminal.

[0011] The above reception control unit fails to receive calling party identifier from the public network, de also request originator identifier to the caller via the voice response connection processing unit <br/> Wear.

That is, as conceptually shown in FIG. 2, when the caller A makes a connection request and an incoming call is made via the public network B, but the caller identifier is not transmitted, the incoming call control unit causes the voice response connection. Control the processing unit. As a result, a voice response signal to the effect that the caller A is requested to dial the caller identifier is transmitted, and the caller A is asked to dial his / her caller identifier (subscriber ID).

Therefore, the incoming call control unit uses the caller identifier sent from the caller to refer to the callee automatic routing table based on the caller identifier in the same manner as above, and refers to one or more arbitrary callees. Search for the terminal number and give priority to the terminal with the registered destination terminal number
You may do it .

[0014] The above reception control unit fails to receive calling party identifier from the PSTN may be incoming to the extension which is preset without reference to the destination automatic routing table.

That is, as conceptually shown in FIG. 3, when a caller A makes a connection request and an incoming call is made via the public network B but the caller identifier is not sent, the incoming call control unit receives the incoming call. It is also possible to make an incoming call to a preset extension (for example, a relay station) based on the existing station line receiving method without referring to the destination automatic routing table .
Yes .

[0016] The present invention is Oite above, receiving controller If the calling party identifier in the destination automatic routing table is detected that is not registered, so as to call the extension which has been set in advance Tei Ru.

That is, as conceptually shown in FIG. 4, when the incoming call control unit receives an incoming caller identifier when an incoming call is made from the outgoing caller A via the public network B by a connection request,
If the destination terminal number corresponding to the caller identifier is not registered in the destination automatic routing table,
Similarly receiving controller and causes the incoming to the extension which is previously set based on the existing office line incoming scheme without reference to the destination automatic routing table.

As a result, even if the called party terminal number corresponding to the caller identifier is not registered in the called party automatic routing table, it is possible to make a call to at least a predetermined extension.

[0019] and also in the present invention, Oite to the above,
Receiving controller after call completion, it is to be newly automatically registered extension that arrive with calling party identifier in the destination automatic routing table.

[0020] That is, when carrying out the call in the incoming call control unit refers to the destination automatic routing table automatic registration and update flag (S), after the call ends If the flag is automatically registered, and the caller identifier The registered extension is automatically registered,
Update the destination automatic routing table.

[ 2 ] In the present invention according to the above-mentioned present invention [ 1 ], when the incoming call control unit receives an automatic registration refusal signal from the incoming call destination terminal, it does not perform automatic registration in the incoming call destination automatic routing table. You can

That is, in the above-mentioned present invention [ 1 ], when an unidentified caller identifier is received in the destination automatic routing table, the incoming call control unit causes the caller to enter the destination automatic routing table after the call ends. Although the identifier and the extension that has arrived are newly automatically registered, in the present invention, if the automatic registration refusal signal such as the button operation or the special number dial from the extension terminal is received, the registration in the data of the destination automatic routing table is rejected. It is possible to do.

[ 3 ] In the present invention according to the above-mentioned present invention [1], when the incoming call control unit receives a data registration / deletion signal from the incoming call destination terminal, the incoming call control unit registers the setting data in the incoming call destination automatic routing table. And can be deleted.

That is, as an off-line process, the incoming call control section can perform registration (update) and deletion of the table data when receiving a data registration / deletion signal from a button operation or a special number dial from the extension terminal.

It should be noted, Oite above, includes the destination automatic routing table last incoming time data, the reception control section, coming from the last incoming time data in the destination automatic routing table call during a predetermined time period by detecting the data of which was not originator identifier may be deleted automatically from the destination automatic routing table.

That is, the incoming call control unit constantly updates the final incoming time for each caller identifier in the destination automatic routing table and periodically refers to it.
The caller ID that has not been received during the set period is deleted.

[0027] Thus the data for infrequent callers can be deleted from the destination automatic routing tables, Ru possible der to suppress the capacity of the destination automatic routing table.

[ 4 ] In the present invention according to the above-mentioned present invention [1], the destination automatic routing table includes data indicating whether or not the call forwarding destination for the destination terminal can be called, and the termination control unit includes: The absent transfer destination can be called according to the call permission / prohibition data.

That is, when the extension of the called party is performing call forwarding, the call control unit calls the call forwarding destination only from the caller identifier registered in the call destination automatic routing table. As a result, unnecessary calls to the unattended transfer destination can be eliminated.

[ 5 ] In the present invention according to the above-mentioned [1] of the present invention, the incoming call control unit receives an instruction from a called terminal,
After talking or ending the call, the incoming call rejection data can be registered in the incoming call destination automatic routing table for the caller identifier.

That is, the incoming call control section can register the caller identifier as an incoming call rejection in the incoming call destination automatic routing table by a manual operation from the extension terminal during the call or at the end of the call.

Thus, after the registration is completed, it is possible to prevent the terminal from receiving an incoming call from the same unidentified caller identifier.

It should be noted, Oite above, the destination automatic routing table, may have different data from day to day.

That is, day and night, weekdays, holidays, public holidays, etc.
By having a plurality of destination automatic routing tables that differ depending on the day, it is possible to change the destination automatic routing table to be searched during time zones such as day and night, weekdays, holidays, and holidays.

As described above, according to the present invention, it is possible to directly call the target terminal by specifying the called party from the caller identifier.

Further, it becomes possible to perform automatic destination registration for an unregistered caller identifier and register / update table data of the callee terminal corresponding to the caller identifier from the terminal.
