Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a private branch exchange that accommodates and connects a private PHS or the like in a campus, for example.
[0002]
[Prior art]
Conventionally, as such a private branch exchange, when a normal extension number designated by a calling terminal is received along with a memory for storing a normal extension number for each extension terminal such as a private PHS and a calling operation from the calling terminal, An extension terminal corresponding to the normal extension number is specified from the memory, and a central control unit is provided for communication connection between the specified extension terminal and the calling terminal.
[0003]
As such a private branch exchange, for example, a private PHS is assigned to each employee, and when the employee is in the office, the private PHS with the normal extension number is carried by simply dialing the normal extension number of the private PHS. It becomes possible to talk with employees. That is, the normal extension number of the premises PHS can be regarded as the personal number of the employee.
[0004]
For example, when a certain employee is promoted to a department manager, the normal extension number of the premises PHS carried by this employee will also be the normal extension number as the department manager. By distributing the in-house telephone number table within the company, the regular extension number of the employee will be recognized internally as the general extension number of the general manager.
[0005]
For example, if the regular extension number of the employee who is the current department manager is 2000 and the regular extension number of the employee who is the new department manager is 2500, the regular extension number of the department manager starts from 2000 when the new department manager replaces the current department manager. Since it is changed to 2500, it is necessary to distribute in the company telephone number table that the general extension number of the general manager has been changed from 2000 to 2500.
[0006]
However, in order to make the normal extension number of the employee a personal number, and to make this normal extension number the normal extension number of the general manager, by distributing the company telephone number table, notice that the extension number of the general manager has changed This notification is very troublesome, and there is a time lag before the general extension number of the general manager is changed.
[0007]
Therefore, in order to cope with such a situation, it is conceivable to prepare a private PHS dedicated to the general manager to which a general extension number dedicated to the general manager is assigned.
[0008]
In this way, by giving a private PHS dedicated to the manager in addition to the employee's private PHS, there is no need to change the manager's normal extension number while making the employee's private PHS normal extension number a personal number. , No need to distribute the internal telephone number table of the change notification.
[0009]
[Problems to be solved by the invention]
However, according to the above-mentioned conventional private branch exchange, in addition to the private PHS of the individual employee, the general PHS dedicated to the general manager is separately provided, and the general extension number of the private PHS of the individual employee is secured as the personal number. Although a dedicated normal extension number can be obtained, the number of on-site PHSs must be secured by the number of positions.
[0010]
The present invention has been made in view of the above points, and an object of the present invention is to respond to, for example, an individual or a job with respect to one extension terminal without increasing the number of local PHS (extension terminals). An object of the present invention is to provide a private branch exchange capable of securing a plurality of extension numbers.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the private branch exchange of the present invention includes a storage means for storing a normal extension number for each extension terminal accommodated therein, and the normal extension number designated by the calling terminal in accordance with a calling operation from the calling terminal. the When outgoing identifies the extension terminal corresponding to the normal extension from the storage unit, a private branch exchange and a control means for communicating connecting the calling terminal with the specified extension terminal, the storage means is for each of the extension terminals, in addition to the normal extension, I storable der multiple dummy number, Ri Contact stores normal extension number corresponding to the dummy number, said control means, said Upon detecting the calling operation from the calling terminal, by referring to the storage means, the calling terminal specified by the number to recognize the normal extension or dummy number, specified numbers in the calling terminal is a dummy number The extension terminal identification means for reading the normal extension number corresponding to the dummy extension number and identifying the extension terminal corresponding to the normal extension number, and the normal extension number or dummy number designated by the calling terminal and a number transmitting means for transmitting specified in extension terminal as said extension terminal, when receiving the normal extension number transmitted by the number transmission means displays the normal extension number on the display unit, When the dummy number is received, display means for displaying the dummy number on the display unit is provided.
[0012]
Therefore, according to the private branch exchange of the present invention, it is possible to make a communication connection to an extension terminal even if a call is made by the normal extension number by adding a dummy number in addition to the normal extension number to one extension terminal Needless to say, the communication connection is made possible even by making a call using a dummy number. For example, if the normal extension number is a personal extension number and the dummy number is a job extension number, the number of extension terminals is increased. Even if it is not, it can be used separately for personal use or job title with a single extension terminal. Also, according to the private branch exchange of the present invention, when a call is received with a normal extension number, the normal extension number received with the call is displayed on the display means, and when a call is received with a dummy number, the call is sent. Because the received dummy number is displayed on the display means, the user on the extension terminal side can recognize whether the call is received with the normal extension number or the dummy number by viewing the display content of the display means. For example, when the normal extension number is a personal extension number and the dummy number is a job extension number, the user of the extension terminal can recognize whether the call is an individual call or a job call.
[0013]
The private branch exchange of the present invention uses the normal extension number of the specified extension terminal as a box number when there is no response from the specified extension terminal to the calling terminal in response to the calling operation by the normal extension number. A voice mail device for recording the voice content from the calling terminal in a memory area corresponding to the number, the voice mail device from the specified extension terminal to the calling terminal according to a calling operation by the dummy number; When there is no response, the dummy number of the specified extension terminal is used as a box number, and the voice content from the calling terminal is recorded in a memory area corresponding to the box number.
[0014]
Therefore, according to the private branch exchange of the present invention, when a normal extension number and a dummy number are used as box numbers and a call is made with the normal extension number, the calling terminal enters the memory area corresponding to the box number of the normal extension number. Of course, when there is a call with a dummy number, the voice content from the calling terminal is recorded in the memory area corresponding to the box number of the dummy number. When the normal extension number is a personal extension number and the dummy number is an extension number for a job title, the user at the extension terminal listens to the recorded content recorded on the voice mail device with the normal extension number or dummy number. You can select a personal content if you want to listen to the recorded content with a normal extension number, or a job title if you want to listen to the recorded content with a dummy number. It can be.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a private branch exchange showing an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration inside a private branch exchange showing the present embodiment.
[0018]
In FIG. 1, a private branch exchange 1 is an in-house switch that accommodates and connects a plurality of extension terminals, and accommodates and connects a plurality of private PHSs (hereinafter simply referred to as PS) 11 that are extension terminals. On-premises base station (hereinafter simply referred to as BS) 12, a plurality of wired telephones 13 that are extension terminals, and voice mail that records the voice content from the calling terminal when the extension terminal to be called is busy or not responding A device (hereinafter simply referred to as VMS) 14, a speech path switch (hereinafter simply referred to as SW) 15 that forms a speech path between the BS 12, the wired telephone 13 and the VMS 14, and various data such as station data and control programs A memory (hereinafter simply referred to as MEM) 16 for storing various data and a central controller (hereinafter simply referred to as CPU) 1 for controlling the private branch exchange 1 as a whole. And it has a door. The PS 11 is provided with a display unit for displaying information and the like.
[0019]
FIG. 2 is an explanatory diagram briefly showing the data contents related to the PS 11 stored in the MEM 16.
[0020]
The MEM 16 includes an extension number area 16A indicating an address number (extension number), and a first area 16B and a second area 16C that store information related to the PS 11 for each extension number.
[0021]
In the first area 16B, a type of extension number, for example, a call destination type indicating whether it is a PS11 normal extension number (personal extension number) or a dummy number (position extension number) is stored. Yes.
[0022]
In the second area 16C, information related to the extension terminal corresponding to the extension number, for example, when the extension number is a normal extension number (personal extension number), information related to the PS11 of the extension number, or the extension number is stored. In the case of a dummy number (extension number for job title), the normal extension number of the corresponding PS 11 is stored.
[0023]
For example, the extension number of the general affairs department manager is 2000, the extension number of the accounting department manager is 2001, and for example, extension numbers from 2000 to 2100 are secured as dummy numbers (extension numbers for positions). deep.
[0024]
If an employee with a normal extension number of 1000 is a general manager of the accounting department, the general manager of the accounting department is a dummy number 2000 in addition to the normal extension number 1000 (personal extension number). A number will be given. At this time, PS is stored in the call destination type of the first area 16B corresponding to number 1000 in the extension number area 16A, the call destination PS information is stored in the call destination information in the second area 16C, and 2000 in the extension number area 16A. A dummy number is stored in the call destination type of the first area 16B corresponding to the number, and a normal extension number “1000” corresponding to the PS11 of the same employee is stored in the call destination information of the second area 16C.
[0025]
In addition, even if the job title is changed, it can be dealt with by simply rewriting the callee PS extension number in the second area 16C corresponding to the dummy number to the normal extension number of the employee who newly assigned the job title.
[0026]
The storage means described in the claims corresponds to the MEM 16, and the control means and the number transmission means correspond to the CPU 17.
[0027]
Next, operation | movement of the private branch exchange 1 which shows this Embodiment is demonstrated. FIG. 3 is a flowchart showing processing operations inside the CPU 17 related to PS communication establishment processing in the present embodiment.
[0028]
The PS communication establishment process shown in FIG. 3 calls the PS 11 specified by the extension number or dummy number from the calling terminal, and when this PS 11 responds, establishes communication between the PS 11 and the calling terminal, and the PS 11 is not activated. In the case of answering or busy, it is a process of establishing communication between the calling terminal and the VMS.
[0029]
In FIG. 3, the CPU 17 determines whether or not an extension number has been received in accordance with the calling operation from the calling terminal (step S <b> 11). If it is determined that the extension number has been received, the CPU 17 determines whether or not the call destination type is PS based on the first area 16B corresponding to the extension number of the MEM 16 shown in FIG. 2 (step S12). ).
[0030]
If it is determined that the call destination type is PS, the extension number is determined to be a personal extension number, and the call destination PS information is read based on the second area 16C corresponding to the extension number (step S13). ), The received extension number is saved in the MEM 16 (step S14). Note that the MEM 16 temporarily stores the extension number received for each outgoing operation.
[0031]
Next, the CPU 17 determines whether or not the PS 11 corresponding to the received extension number is currently busy (step S15). If it is determined that the PS 11 is not currently busy, a PS call timer is started (step S16).
[0032]
When starting the PS call timer, the CPU 17 executes a call operation to the PS 11 corresponding to the received extension number (step S17), and determines whether or not the PS call timer started in step S16 has expired (step S17). Step S18). The CPU 17 notifies the PS 11 of the extension number received in step S11 during the PS calling operation in step S17. Accordingly, when receiving the extension number notified from the CPU 17, the PS 11 side displays the extension number on the display unit.
[0033]
If the PS call timer has not timed up, the CPU 17 determines whether or not the PS 11 that is currently calling has responded (step S19). If the PS 11 that is currently in the call operation responds, the CPU 17 ends the processing operation by establishing communication between the calling terminal and the PS 11 (step S20).
[0034]
If the PS call timer has expired in step S18, the CPU 17 determines whether or not the VMS 14 can be called (step S21). If it is determined that the VMS 14 can be called, the communication with the PS 11 that is currently calling is disconnected (step S22), and the calling operation for the VMS 14 is executed (step S23).
[0035]
Further, when executing the calling operation to the VMS 14, the CPU 17 determines whether or not a response from the VMS 14 has been detected (step S24). If a response from the VMS 14 is detected, the CPU 17 transmits the extension number saved in step S14 to the VMS 14 as a box number (step S25), and sends the extension number from the transmitting terminal to the memory area of the VMS 14 corresponding to the box number. By establishing communication between the VMS 14 and the calling terminal to record the voice content (step S26), this processing operation is terminated.
[0036]
If it is determined in step S12 that the callee type is not PS based on the first area 16B corresponding to the extension number, the CPU 17 determines that this callee type is a dummy number (position extension number). Then, the called PS extension number is read based on the second area 16C corresponding to this extension number (step S27).
[0037]
Further, the CPU 17 searches the extension number area 16A for an extension number corresponding to this call destination PS extension number, reads out the call destination PS information of the second area 16C corresponding to this searched extension number (step S28), and step In order to save the extension number received in S11, that is, the dummy number in the MEM 16, the process proceeds to step S14.
[0038]
If the PS 11 corresponding to the extension number is currently busy in step S15, the process proceeds to step S21 to connect to the VMS 14.
[0039]
The extension number saved in step S25 is used as the box number of the VMS 14, and the voice content from the calling terminal is recorded in the memory area corresponding to the box number. This box number is received from the calling terminal. When the extension number is a dummy number, the voice content is recorded in the memory area of the box number corresponding to the dummy number (extension number for the job title) and the extension number received from the calling terminal is a normal extension number. Is adapted to record voice contents in a memory area of a box number corresponding to a normal extension number (personal extension number).
[0040]
If the extension number is not received in step S11 with the transmission operation from the transmission terminal, this processing operation is terminated.
[0041]
On the PS11 side that has received a call operation in step S17, when a call is received with a normal extension number, the normal extension number that has received the call is displayed on the display unit, and when a call with a dummy number is received. The dummy number that received the call is displayed on the display unit.
[0042]
According to the present embodiment, by assigning a dummy number in addition to the normal extension number to one PS11, it is possible to connect to the PS11 even with the normal extension number. However, since the communication connection is made possible, for example, when a normal extension number is a personal extension number and a dummy number is an extension number for a job title, an individual PS11 can be used without increasing the number of PS11. Can be used for different purposes or positions.
[0043]
On the PS11 side, when a call is received with a normal extension number, the normal extension number that received the call is displayed on the display unit. When a call is received with a dummy number, the dummy number that received the call is displayed. Is displayed on the display unit, the user on the PS11 side can recognize whether the call is received with the normal extension number or the dummy number by viewing the display content on the display unit. When receiving an outgoing call with an extension number, it is possible to recognize to some extent whether it is an incoming call with personal contents or an incoming call with a dummy number.
[0044]
According to the present embodiment, when the PS 11 that has received a call with a normal extension number is not responding or busy, the voice content is recorded in the memory area of the box number corresponding to the normal extension number. In addition, when the PS 11 that has received a call with a dummy number is not responding or busy, the audio content is recorded in the memory area of the box number corresponding to this dummy number. You can listen to your recorded content recorded on VMS14 with extension number or dummy number. When listening to recorded content with normal extension number, personal content, when listening to recorded content with dummy number Can be selected according to the job title.
[0045]
In addition, according to the present embodiment, when a user on the calling terminal side wants to call PS11 as an individual, he or she uses a normal extension number to make a call, and if a user wants to call PS11 as a title, it is a dummy. Since the number is used to make a call, the dial number used can be used for personal use or job use.
[0046]
Further, according to the present embodiment, even if the position is changed, the calling party PS extension number registered in the second area 16C of the dummy number corresponding to the position is changed to the normal extension number of the employee newly assigned to the position. It is possible to respond quickly to changes in position simply by rewriting to.
[0047]
In the above embodiment, the PS 11 is taken as an example of the extension terminal to which the normal extension number and the dummy number are assigned. However, the extension terminal to which the normal extension number is assigned, for example, the wired telephone 13 or the like may be used. Needless to say, similar effects can be obtained.
[0048]
In the above embodiment, a single extension number is assigned to one extension terminal in addition to the normal extension number, but it goes without saying that a plurality of dummy numbers can also be assigned. .
[0049]
In the above embodiment, for convenience of explanation, the dummy number has been described as the extension number of the job title. However, the extension number is not limited to the job title or the like. In other words, the normal extension number is set by one extension terminal. Needless to say, the technical content that a plurality of dummy numbers can be obtained is the main point of the present application.
[0050]
【The invention's effect】
According to the private branch exchange of the present invention configured as described above, a dummy number is assigned to one extension terminal in addition to the normal extension number, so that communication with the extension terminal can be performed even when a call is made by the normal extension number. As a matter of course, it is possible to connect even if a dummy number is sent, so for example, if a normal extension number is a personal extension number and a dummy number is a job extension number, Even if the number of terminals is not increased, one extension terminal can be used for personal use or for post office use.
[0051]
According to the private branch exchange of the present invention, when a normal extension number and a dummy number are used as box numbers and a call is made with the normal extension number, the voice from the calling terminal is stored in the memory area corresponding to the box number of the normal extension number. In addition to recording the contents, when there is a call with a dummy number, the voice content from the calling terminal is recorded in the memory area corresponding to the box number of this dummy number. If the number is a personal extension number and the dummy number is an extension number for a job title, the user on the extension terminal side must listen to the recorded content recorded on the voice mail device with the normal extension number or dummy number. You can select a personal content when listening to the recorded content with an extension number, or a job title when listening to the recorded content with a dummy number. Can.
[0052]
According to the private branch exchange of the present invention, when a call is received by a normal extension number, the normal extension number received is displayed on the display means, and when a call is received by a dummy number, the call is received. Since the dummy number is displayed on the display means, the user on the extension terminal side can recognize whether the call is received with the normal extension number or the dummy number by viewing the display content of the display means, For example, when the normal extension number is a personal extension number and the dummy number is a job extension number, the user of the extension terminal can recognize whether the call is an individual call or a job call.
