Abstract

PURPOSE:To easily specify a desired answering subscriber with its proper number and to attain the talking by adding the proper numbers to each answering subscriber together with the telephone number of the remote side for calling. CONSTITUTION:A memory means stores the user numbers to answer the circuits in response to each of those circuits which are allocated by a number allocating means that secures the correspondence between the positions of stored circuit and the numbers proper to these circuits. Then the called subscriber numbers and the telephone numbers of the called subscriber numbers specified by those called subscriber numbers are stored in a telephone exchange device in response to each other. Thus a desired called subscriber is surely called when the called subscribers are called. Then the talking is possible for each extension user even in case a single piece of extension is used by plural users.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone exchange system that accommodates a plurality of extension lines and controls calls between the lines.

[Prior Art] A conventional private branch telephone switching system allocates a unique number to each extension, and when a call is made to the assigned number, the extension corresponding to the number is selected, and the telephone connected to the extension is was sending out a ringtone.

There are usually multiple responders to the extension, with 3 to 3 people responding.
Usually there are about 5 people. Furthermore, in such cases, multiple telephones are often connected to one extension line.

[Problems to be Solved by the Invention] However, in the conventional example described above, there are three to five users for one extension line, and a plurality of telephones are connected. Therefore, even if one of the users of that extension is moving to another location for a meeting or the like, the caller will be able to make the call assuming that the user assigned to that extension is at the telephone location of that extension. I'll call you.

However, the desired responder is not in the vicinity of the telephone set, resulting in wasted call processing, and even if the call is transferred to the responder, it is extremely troublesome.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as one means for solving the above-mentioned problems.

In other words, in a telephone switching system that houses multiple extension lines, assigns a unique user number to each user who uses a telephone terminal connected to the housed extension lines, and controls calls between the lines, each housed extension line is a number assigning means for associating a line position with a line number unique to the line; a storage means for storing the user number to be responded to in association with each line assigned by the number assigning means; specifying means for specifying the location of the receiving line to which the corresponding user responds, which is specified by the telephone number and user number identified; and communication path forming means for forming a communication path between the line specified by the specifying means; Equipped with.

[Operation] With the above configuration, by adding a unique number for each responder together with the telephone number of the other party and making a call, it is possible to easily identify the desired responder using the number and make the call possible. .

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of a private telephone exchange system according to an embodiment of the present invention. In the figure, 1 to 3 are extensions stored in the telephone exchange, and extension 1 has a '20'. "21" is assigned to extension 2, and "°22" is assigned to extension 3. In addition, three telephones 31 to 33 and 41 to 43 are connected to extension 1 and extension 2, respectively, and the telephones used are A, B, C, D, E, and
He has become an F person.

Further, extension 3 is an extension arranged in the conference room, and one telephone 35 is connected thereto. Reference numeral 4 denotes an extension interface circuit for controlling the extension lines, 5 a communication path switch for forming communication paths between each extension line and the outside line 20, 6 a communication path control device for controlling the communication path switch 5, and 7 a memory. 8 is a central control unit that controls the entire embodiment according to the programs shown in FIGS. 2 and 3, which will be described later. 8 is a numeric oil translation table, an incoming call translation table, and a called party, which will be described later in addition to the programs mentioned above. A memory 9 stores an identification storage position table, etc., and a trunk circuit 9 stores an outside line 20. - The basic exchange operation of this embodiment having the above configuration will be explained below with reference to the flowchart of FIG.

In the following explanation, D (extension user number "2"), who normally uses extension 2, moves to a conference room where extension 3 is installed, and from then on all calls made to D on extension 2 will be made. Performs control to instruct transfer to extension 3 (transfer control to extension number "22").Here, A
, B, and C's extension numbers are "2" and °゛1, respectively.
, "°0P" and use extension 2, and set the extension numbers of E and F to 2, "1", and "O", respectively.

In step S1, the person (D) who activates the telephone exchange equipment normally uses the extension 2 to off-hook the handset (not shown) of the telephone set to the telephone exchange equipment, and issues a call request. Subsequently, as shown in step S2, the callee number or forwarding destination registration number is input using a desired telephone number key.

Therefore, in step S3, the central control unit 7 of the telephone exchange receives a signal from the connected extension that requested a call via the extension interface circuit 4, and checks whether or not the "arrow" button has been pressed. . This "Ku" button is a button that indicates that you can specify the forwarding destination registration for automatic forwarding when a call is received to you.If the "Straw" button is sent, you can enter the forwarding destination registration command. In addition, here we have assigned "Blue" as the transfer destination registration command, but you can assign any button as long as it is distinguishable from others.In the central controller 7, this "° arrow" ”
When a telephone number signal corresponding to is detected, the subsequent telephone 41
The input data will be received as transfer destination designation data.

Although FIG. 2 is still being explained, the forwarding destination registration process, in which the telephone user specifies the registration of the forwarding destination to which he/she wishes to be forwarded when a call is received, will be explained with reference to FIG. 3. This will be explained below.

First, when registering this forwarding destination, as in step S21, take the handset of the telephone off-hook and issue a call request, and then specify the registration of the forwarding destination to which you would like to be forwarded when a call is received to you. Input the registered command ゛′ arrow button. Next, in step S23, press the telephone number button to enter the extension number assigned to you, for example, "
2". Next, as shown in step S24, the destination extension number of D is dialed "°22".

Then, in step S25, the device waits for D to be disconnected and enters the initial state.

Here, the structure of the dialed number translation table in the memory 8 and the called party identifying process using this table will be explained.

In the case where there is no forwarding destination registration as shown in FIG. 3, the central control device 7 stores the memory 8
The destination extension is specified using the dial number-to-accommodation location conversion table shown in FIG. For example, when specifying extension 2 (extension number 22), which is the destination of the telephone call to D,
First digit translation table input The first digit of the phone number (
Find the second numeric translation table address storage location at the location specified in step 2), and refer to the storage address at the location to calculate the second number translation table address.
Find the reference address of the numeric translation table. Then the second
Find the storage position specified by the number (2) in the digit. Then, the call destination is specified by referring to the information stored in the location. If there is no forwarding destination registered, this storage location information will be used as storage location information such as the recipient storage location (for example, extension 2),
Called party usage status data, etc. will be stored.

Next, when the transfer destination is registered by the process shown in FIG. 3, the dial numeral translation table shown in FIG. 5 is created, and the receiving location is specified based on the table. When registering the table, the forwarding destination number is input in step S24, so first, the table is translated using D's normal extension number "21" and D's extension number "2°" inputted in step S23. , find the called party storage position and called party usage status storage position of D in the called party identification storage position table. In this case, replace the receiving position of D in the receiving position shown in FIG. 4 with the called party identification information and called party identification storage position information address. .and,
The reference position of the called party identification accommodation table is specified based on the called party identification accommodation location information address, the called party identification accommodation position is specified based on the subsequent called party number, and the forwarding destination extension number (
22) is stored. As a result, all subsequent calls to D will be forwarded to D specified at this storage position.
22".

Returning to the explanation of the basic exchange operation flowchart in FIG. 2. As a result of registering the transfer destination and specifying the recipient in this way, the calling party can specify the recipient and make a call.

Therefore, in step S3, it is determined whether or not the calling party (eg, B) has specified and inputted the extension user number of, for example, D. If B does not dial D's extension user number, the translation using the dialed number translation table in FIG. 5 ends at the time of retrieval of the incoming call translation table, so the process advances to step S5. However, if B specifies and inputs D's extension user number, then step S3 will change to step S4.
In the translation using the dial digit translation table in FIG. 5, the search is performed using the called party identification accommodation position table. Next, in step S5, it is checked whether the called party is busy or not based on information such as the receiving party's storage position and the usage status of the called party obtained as a result of the dial digit translation. If the called party is busy, the process advances to step S15 and step S16, where a busy tone is sent until the caller goes off-hook, and when the caller goes off-hook, the process advances to step S17, where the line is released and restored, and a series of call processing is performed. end. After this, it will return to the initial state again.

If the called party is not busy in step S5, the process advances to step S6, where it is determined whether or not the communication path connecting the calling party and the called party is empty, and if an empty communication path exists. If not, the process proceeds to step S15 and subsequent steps.

If the call route (selected extension) is not in use, the process advances from step S6 to step S8, where the called destination line is identified and the call route is set, and then step S9 and step S
At IO, it sends a paging signal to a specific extension, ie, a designated called party, and waits for D's response. Here, if there is a response (off-hook) from the specific extension-connected telephone, the process proceeds to step Sll, where the calling destination line and the called line are connected to form a communication path, and the call is enabled. At the same time, the usage status of the called party in the called party identification storage position table shown in FIG. 5 is set to call status. Next, in step S12, it is determined whether the call has ended and on-hook has been established. When the call ends and the user is on-hook, the process advances from step S12 to step S17, and the process ends. At this time, the usage status of the called party in the called party identification storage position table shown in FIG. 5 is set to enable the call, which is from the call in progress to the end of the call.

As explained above, according to this embodiment, the telephone exchange device
By storing the called party number and the telephone number of the called party's location specified by the called party number in association with each other, it is possible to ensure that the desired call is received when the called party is called. Even when a caller is called and multiple people use one extension, the transfer destination can be specified and transferred for each extension user.

You can now make calls.

[Effects of the Invention] As explained above, according to the present invention, the desired caller can be reliably identified, and the call can be automatically transferred to the telephone where the desired caller is located, quickly and without any troublesome operations. You can talk to the desired party.
