  ADVANTAGE OF THE INVENTION According to this invention, the registration operation | work for regulating an outside line transmission function can be simplified.

(Overview)
In advance, an outside line transmission restriction information memory capable of setting transmission restriction settings for each phone book group is prepared, and phone numbers that are not restricted when calling a phone book are registered in a telephone book group that does not restrict outgoing calls. In addition, when the phone book registration is completed in advance, it is possible to additionally register only the grouping with respect to the phone numbers registered in advance, so compared with the case of registering a new phone number. Work can be simplified.

  After making such registration, the other party who started the outside line transmission via the telephone switching device automatically or after any incoming call response such as callback function, additional number dial-in, exclusive connection of dedicated line and IVR function Compare the phone number with the phone number registered in the phone book. If the phone numbers match, if the phone book group is set to "Do not restrict", allow outgoing calls. If set to "Restrict" Restrict outgoing calls. If the phone number is not registered in the phone book, outgoing calls are unconditionally restricted.

(Embodiment of the present invention)
A telephone exchange device according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram of a telephone exchange apparatus according to an embodiment of the present invention. The telephone exchange apparatus according to the embodiment of the present invention assumes a button telephone apparatus, a private branch exchange telephone apparatus (PBX), or a connection apparatus configured to realize this function as a main function.

  In the embodiment of the present invention, as shown in FIG. 1, when an incoming call from a first external line L # i (i is any one of 1 to n) is included, an available second external line L # j (j is any one of 1 to n, i ≠ j), and an outside line transmission control unit 1 that makes a call from the second outside line L # j in response to the outside line call request, and an outside line call request This is a telephone exchange device that includes a regulation execution unit 2 that regulates outgoing line transmission and a telephone directory memory 3 that holds information on registered telephone numbers.

  The telephone directory memory 3 includes a group registration area 32 that holds identification information of a group to which the telephone number belongs for each piece of telephone number information, and an outside line transmission restriction information memory 4 that holds restriction information for outside line transmission for each group. And when the outside line transmission request is received, the regulation execution unit 2 searches the telephone directory memory 3 for a group to which the telephone number of the transmission source of the outside line transmission request belongs, and sets up the outside line transmission regulation information in the retrieved group. A search is performed based on the outgoing call restriction information memory 4, and outgoing line outgoing calls are restricted based on the search result.

  Other components include an external line interface unit 7 that accommodates external lines L # 1 to L # n, an external line call control unit 6 that includes an incoming call control unit 9 and an outgoing call control unit 10, an internal line interface unit 8 that accommodates internal lines, and voice. A guidance control unit 5 is provided. Since these functional blocks are based on a known technique, detailed description is omitted. The external lines L # 1 to L # n are ISDN (Integrated Serviced Digital Network) lines, analog lines, VoIP (Voice over IP) lines, etc., and the external lines L # 1 to L # n are physical transmission lines. Or it may be a logical transmission line.

  Next, a registration procedure in the embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram for explaining a registration procedure of a telephone directory and a group and an outside line transmission restriction in the embodiment of the present invention. When the user performs a menu setting operation on the extension telephone (step S0), a menu is displayed (step S1).

  The contents of the menu are “1: phone book”, “2: outside line call”, “3: outside line call”, and “4: hold”. When the user selects “1: phone book”, “1: common phone book registration”, “2: group name setting”, “3: ringing setting for each group”, “4: group destination setting”, “ Detailed menus such as “5: Delete all common phone books”, “6: Callback for each group”, and “7: Restrict outgoing line” are displayed. Note that “2: outside line transmission”, “3: outside line incoming call”, and “4: hold” are not directly related to the present invention, and thus description thereof is omitted.

  Further, when “7: Outbound transmission restriction” is selected, a function for setting the external transmission restriction in a group unit is activated. When setting outgoing line restrictions on a group basis, it is possible to individually set which group to restrict outgoing calls to all displayed groups (steps S3 and S4).

  As “other settings” in step S5, when “1: common phone book registration” is selected, a function for registering a phone number and a group to which the phone number belongs to the phone book memory 3 is activated. Is done. When “2: Group name setting” is selected, a function for setting a group name is activated. When “3: ringing setting for each group” is selected, a function for setting a ringing tone to a different tone for each group is activated. When “4: group destination setting” is selected, a function for setting the destination to a different destination for each group is activated in the case of forwarded call when there is no call. When “5: Delete all common phone books” is selected, a function for erasing all phone books registered in the phone book memory 3 is activated. When “6: Callback for each group” is selected, a function for setting a callback function in units of groups is activated.

  Next, an example of callback relay transmission will be described with reference to FIG. FIG. 3 is a sequence diagram showing a processing procedure of callback relay transmission. The mobile phone 20 in FIG. 3 is a terminal of a user who makes an external line transmission request, and the extension terminal 23 is a terminal to which a telephone number for making an external line transmission request is set. Therefore, the extension terminal 23 does not need to actually respond to the incoming call.

  When the user requests an outside line call, the call is sent from the mobile phone 20 to the extension terminal 23 (step S10). This call is received by the telephone exchange device 22 via the communication carrier network 21 (step S11).

  Since the incoming call in step S11 is addressed to the extension terminal 23, the external line transmission control unit 1 of the telephone exchange device 22 makes a call by recognizing that the incoming call requests an external line transmission (step S12). This call arrives at the mobile phone 20 (step S13). At this time, the outside line transmission control unit 1 starts the timer 24. Furthermore, although the incoming call is also received at the extension terminal 23 (step S14), the extension terminal 23 does not respond here.

  When the user of the mobile phone 20 confirms the call in step S13, the user disconnects the call (step S15). As a result, the call is abandoned (step S16), and the incoming call is stopped (step S17). Although illustration is omitted, at this time, if call abandonment (step S16) is not performed even if the timer 24 times out, the probability that the incoming call in step S11 is not for requesting an outgoing call It is determined that the value is high, and the process is interrupted.

  Upon receiving the call abandonment in step S16, the outside line transmission control unit 1 of the telephone exchange device 22 makes a call (step S18) and dials the telephone number of the mobile phone 20 (step S19). In addition, the timer 24 is activated at the time of transmission in step S18.

  In FIG. 3, transmission (step S18) and dialing (step S19) are made to the communication carrier network 25. This is because the mobile phone 20 makes a call to the communication carrier network 21 in step S10. This indicates that the user has moved to the area of the user network 25.

  When an incoming call is made to the mobile phone 20 (step S20) and the mobile phone 20 responds (step S21), a response arrives at the telephone exchange device 22 (step S22), and a call is in progress (step S23). Although illustration is omitted, at this time, if the response (step S22) is not performed even when the timer 24 expires, the mobile phone 20 determines that the probability of abandoning the external line transmission request is high. To interrupt the process.

  When a call is in progress in step S 23, the voice guidance control unit 5 of the telephone exchange device 22 sends a message “Please give me an outside line calling number and a telephone number” to the mobile phone 20. The user of the cellular phone 20 who has listened to the voice guidance inputs “the first digit of the outside line transmission number” by a PB (Push button) signal (step S24). Similarly, the input up to "the outside line transmission number nth digit" is input (step S25). The telephone exchange device 22 captures an outside line different from that during communication (step S26).

  Subsequently, the user of the mobile phone 20 inputs his / her phone number from “first dial digit” (step S27) to “dial n digit” (step S28) by the PB signal. Note that steps S27 and S28 can be omitted when the telephone exchange device 22 is automatically notified of the telephone number of the caller, such as a number display function.

  The restriction implementation unit 2 of the telephone exchange device 22 searches the telephone directory memory 3 to check whether the telephone number of the mobile phone 20 is registered in the telephone directory. As a result, when it matches the telephone number registered in the telephone directory and the group belongs to the “unregulated” group (Yes in step S29), a call is made to the telecommunications carrier network 26 using the captured external line ( In step S30), the communication device 27 is received (step S31). Further, as a result of the search, when the telephone number registered in the telephone directory does not match or matches, but the group belongs to the “restricted” group (No in step S29), the restriction is implemented.

  The communication device 27 responds to the incoming call in step S31 (step S32), and this response arrives at the telephone exchange device 22 via the communication carrier network 26 (step S33) and is in a call (step S34). .

  The capturing of the outside line in step S26 may be performed after it is determined in step S29 that the mobile phone 20 belongs to the group that does not restrict outside line transmission. In order to shorten the time from when it is determined to belong to the “No” group until the transmission of step S30 is actually performed, it is desirable to make the sequence diagram of FIG.

  In the lower part of FIG. 3, specific examples of the telephone directory memory 3 and the outside line transmission restriction information memory 4 are illustrated. The telephone number in the telephone directory memory 3 is necessary for using the normal telephone function regardless of the outside line transmission, and is an item registered in advance by each user or administrator. In addition, grouping is often an item that is registered in advance by individual users or managers for the purpose of identifying members belonging to the same department or members related to the same project regardless of outside line transmission.

  In the embodiment of the present invention, in the embodiment of the present invention, simple additional registration for setting whether or not to restrict the outside line transmission for each telephone book group is performed in the embodiment of the present invention for the items registered in advance as described above. Therefore, it is possible to regulate outgoing line transmission.

  Next, another embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a plurality of different restriction types in another embodiment. In another embodiment, a plurality of different restriction types are provided as shown in FIG. 4 instead of the restriction type of “restrict” or “not restrict”.

  The restriction type is, for example, a type such as “no restriction”, “not possible to make an outside line call”, “can make a call only within a local call”, and “can make a call via an operator”. According to this, it is not simply “restricting” or “not restricting” outgoing line transmission, and finer restriction can be performed.

(effect)
A memory capable of setting the outgoing call restriction setting for each phone book group is prepared in advance, and the outgoing call restriction can be realized only by registering the telephone number for which the outgoing call is not restricted to the telephone book group not restricted for outgoing call when registering the phone book.

  In this way, the user can generally register intuitively by using the telephone book without using a dedicated registration memory for outgoing call regulation.

  According to the present invention, it is possible to simplify the registration work for regulating the outside line transmission function, so that the convenience of the user or administrator of the telephone exchange device can be improved.

It is a block block diagram of the telephone exchange apparatus of embodiment of this invention. It is a figure for demonstrating the registration procedure of the telephone directory and group in the embodiment of this invention, and an outside line transmission control. It is a sequence diagram which shows the processing procedure of callback relay transmission. It is a figure which shows the several different regulation classification in other embodiment.
