(Embodiment)
A communication management device, a communication management method, a communication management program, and a communication management system according to embodiments of the present invention will be described below.
FIG. 1 is an overall configuration diagram showing a communication management system 1 as an embodiment of the present invention.
The communication management system 1 includes a Tokyo head office communication system 100, an Osaka branch communication system 200, and a cloud PBX server 30 (communication management device). These Tokyo head office communication system 100, Osaka branch communication system 200, and cloud PBX server 30 are connected via a network such as the Internet, for example. Furthermore, the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via a VPN (Virtual Private Network).

The Tokyo head office communication system 100 includes Tokyo extension telephone terminals 10 and 11 (telephone terminals), a communication section 12, and a telephone communication section 13.
The Tokyo extension telephone terminals 10 and 11 are, for example, IP telephones, and are each set with a local IP address (indicated as "LIP" in the figure). For example, the local IP address of the Tokyo extension telephone terminal 10 is set to "0.0.1.10", and the local IP address of the Tokyo extension telephone terminal 11 is set to "0.0.1.11". There is.
Note that the local IP address is composed of a network address part (indicated by "NA" in the figure) and a host part. In this embodiment, for example, of the local IP address of the Tokyo extension telephone terminal 10, the part "0.0.1" from the left end is set as the network address part, and the part "10" from the right end is set as the host part. .
These Tokyo extension telephone terminals 10 and 11 are connected to a communication section 12.

The communication unit 12 includes various communication devices that transmit and receive information to and from internal devices and external devices, and includes, for example, a router. The communication unit 12 is installed in the same area where the Tokyo extension telephone terminals 10 and 11 are installed, and is connected between the Tokyo extension telephone terminals 10 and 11 and the cloud PBX server 30. A global IP address (indicated as "GIP" in the figure) is set in the communication unit 12. The global IP address of the communication unit 12 is set to, for example, "0.0.0.15". The communication section 12 is connected to the telephone communication section 13.
The telephone communication unit 13 is comprised of various communication devices that transmit and receive information between the Tokyo extension telephone terminals 10 and 11 and external telephone terminals, and includes, for example, a fixed telephone gateway and an optical network unit (ONU). It is what it is. The telephone communication section 13 is installed in the same area as the communication section 12, and allows calls to be made between the Tokyo extension telephone terminals 10, 11 and outside telephone terminals.

The Osaka branch communication system 200 includes Osaka extension telephone terminals 20 and 21 (telephone terminals), a communication section 22, and a telephone communication section 23.
The Osaka extension telephone terminals 20 and 21 are, for example, IP telephones, and are each set with a local IP address. For example, the local IP address of the Osaka extension telephone terminal 20 is set to "0.0.2.20", and the local IP address of the Osaka extension telephone terminal 21 is set to "0.0.2.21". There is.
In this embodiment, for example, of the local IP address of the Osaka extension telephone terminal 20, the part "0.0.2" from the left end is set as the network address part, and the part "20" from the right end is set as the host part. .
These Osaka extension telephone terminals 20 and 21 are connected to a communication section 22.

The communication unit 22 includes various communication devices that transmit and receive information to and from internal devices and external devices, and includes, for example, a router. The communication unit 22 is installed in the same area where the Osaka extension telephone terminals 20 and 21 are installed, and is connected between the Osaka extension telephone terminals 20 and 21 and the cloud PBX server 30. A global IP address is set in the communication unit 22. The global IP address of the communication unit 22 is set to, for example, "0.0.0.25". The communication section 22 is connected to a telephone communication section 23.
The telephone communication section 23 is comprised of various communication devices that transmit and receive information between the Osaka extension telephone terminals 20 and 21 and external telephone terminals, and includes, for example, a landline telephone gateway and an ONU. The telephone communication section 23 is installed in the same area as the communication section 22, and allows calls to be made between the Osaka extension telephone terminals 20 and 21 and the outside telephone terminal.

The cloud PBX server 30 is a cloud-type PBX server that allows telephone calls to be made over the Internet, and is realized by, for example, a computer functioning as a server. This cloud PBX server 30 includes a control section 31, a communication section 32, and a storage section 33.
The control unit 31 is realized, for example, by a calculation means such as a processor or a CPU, functions in cooperation with various memories, storage means such as a hard disk, and executes various programs.
This control section 31 includes a communication control section 31A (regulation control section) and a registration control section 31B.

When the communication control unit 31A receives call requests from the Tokyo extension telephone terminals 10 and 11 and the Osaka extension telephone terminals 20 and 21, it transmits a call request instruction to the communication unit 12. Furthermore, when the communication control unit 31A receives a call request from an outside line telephone terminal, it transmits a reception instruction to the communication unit 12. Furthermore, when a call request is input from the Tokyo extension telephone terminal 10, 11 and the Osaka extension telephone terminal 20, 21 to the outside telephone terminal via the communication section 12, 22, the communication control unit 31A determines that the call request is an emergency call request. Determine whether or not. When determining that the call request is an emergency call request, the communication control unit 31A determines whether the global IP address transmitted from the communication unit 12 matches the registered global IP address stored in the storage unit 33. . If the communication control unit 31A determines that these global IP addresses do not match, it restricts call requests. Further, if the communication control unit 31A determines that the call request is an emergency call request and determines that the global IP addresses match, the communication control unit 31A transmits the calls from the communication unit 12 to the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21. It is determined whether the network address part of the local IP address and the registered network address part stored in the storage unit 33 match, and if it is determined that they do not match, the call request is restricted.

When the registration control unit 31B inputs a registration request from the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21, the registration control unit 31B inputs the global IP address sent from the communication unit 12 and the registered global IP address stored in the storage unit 33. Determine whether or not the address matches. If the registration control unit 31B determines that these global IP addresses do not match, it causes the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 that have sent the registration request to perform emergency call imperceptibility settings, which will be described later. If the registration control unit 31B determines that the global IP addresses match, the registration control unit 31B also controls the network address part and the storage unit of the local IP addresses of the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21 sent from the communication unit 12. 33, and if they do not match, an emergency message is sent to the Tokyo extension telephone terminal 10, 11 or the Osaka extension telephone terminal 20, 21 that sent the registration request. Make the outgoing call invisible setting. Further, if the registration control unit 31B determines that the global IP address matches and the network address part matches, the registration control unit 31B sends an emergency message to the Tokyo extension telephone terminal 10, 11 or the Osaka extension telephone terminal 20, 21 that sent the registration request. Make the outgoing permission perception settings.

The communication unit 32 includes various communication devices that transmit and receive information to and from internal and external devices. The communication unit 32 inputs the local IP address and global IP address transmitted from the communication unit 12 to the communication control unit 31A. The communication unit 32 also transmits to the communication unit 12 a call request instruction from the communication control unit 31A, and an emergency call prohibition instruction or an emergency call permission instruction from the registration control unit 31B.
The storage unit 33 includes, for example, a hard disk or a memory, and stores various programs, work data, and the like. Furthermore, the storage unit 33 stores an emergency number, a global IP address, and a network address section. That is, the registration control unit 31B stores the emergency number in the storage unit 33 in advance through a storage operation by the cloud PBX service provider. Further, the registration control unit 31B automatically stores the global IP address and network address part in the storage unit 33 in advance.
The emergency number is a telephone number for emergency contact, and is set to, for example, "110" or "119."
In the storage unit 33, a global IP address that allows an emergency call request is set, and the address that is accepted and stored in the storage unit 33 becomes a registered global IP address. For example, "0.0.0.15" is stored as the registered global IP address. Note that the registered global IP address here is the global IP address of the communication unit 12.
In the storage section 33, the network address field is set to allow an emergency call request, and the registered network address field is the one that allows the emergency call request and is stored in the storage section 33. For example, "0.0.1" is stored as the registered network address section. Note that the registered network address section here is the network address section within the Tokyo head office communication system 100.

Next, registration processing in the communication management system 1 and the cloud PBX server 30 will be explained.
FIG. 2 is a sequence diagram showing the flow of registration processing from the Tokyo head office communication system 100 to the cloud PBX server 30.
Note that user identification information, an emergency number, a registered global IP address, and a registered network address section are stored in advance in the storage unit 33 of the cloud PBX server 30 by the cloud PBX service provider.
The user identification information is information for identifying a user who can use the cloud PBX service provided by the cloud PBX server 30, and includes, for example, a user ID and password.
For example, "110" and "119" are stored as emergency numbers.
As the registered global IP address, for example, the global IP address "0.0.0.15" of the communication unit 12 is stored.
As the registered network address section, for example, the network address section "0.0.1" of the local IP address "0.0.1.10" in the Tokyo head office communication system 100 is stored.

Note that since the registration processing flow using the Tokyo extension telephone terminals 10 and 11 is the same, only the registration processing flow using the Tokyo extension telephone terminal 10 will be described here.
First, the user operates the Tokyo extension telephone terminal 10 to register with the cloud PBX server 30. That is, the Tokyo extension telephone terminal 10 transmits a registration request to the communication department 12 via the in-house LAN (step S1). This registration request includes user identification information, registration request information, and a local IP address set in the Tokyo extension telephone terminal 10 itself. This local IP address is set to "0.0.1.10", for example.
Upon receiving the registration request, the communication unit 12 transmits the registration request to the cloud PBX server 30 via the Internet (step S2). This registration request includes user identification information, registration request information, the local IP address of the Tokyo extension telephone terminal 10, and the global IP address set for the communication unit 12 itself. This global IP address is set to, for example, "0.0.0.15".

The communication unit 32 of the cloud PBX server 30 receives the registration request and outputs it to the control unit 31. The registration control unit 31B receives the registration request and performs registration processing (step S3). That is, the registration control section 31B determines whether or not the input user identification information is stored in the storage section 33, and if it is determined that the input user identification information is stored, outputs a communication permission instruction to the communication control section 31A. The communication control unit 31A maintains an online state so that the Tokyo head office communication system 100 and the Osaka branch communication system 200 can communicate with outside line telephone terminals at any time. On the other hand, if the registration control section 31B determines that the input user identification information is not stored in the storage section 33, the registration control section 31B causes the Tokyo extension telephone terminal 10 to display registration impossible information via the communication section 12.

Further, when the registration control unit 31B performs the registration process, the registration control unit 31B extracts the global IP address included in the registration request sent by the communication unit 12, and extracts the global IP address and the registered global IP address stored in the storage unit 33. It is determined whether they match (step S4). If the registration control unit 31B determines that they do not match (step S4: No), it transmits an emergency call prohibition instruction to the communication unit 12 via the communication unit 32 (step S5). At this time, the registration control unit 31B may output an emergency call prohibition instruction to, for example, the display unit of the cloud PBX server 30, and display on the management interface of the display unit that emergency calls are not allowed. . Note that the perception setting may be other than display, as will be described later.
Note that the emergency start prohibition instruction is used to inform users that calls to the emergency number will not be connected even if they call the Tokyo extension telephone terminal 10, 11 and Osaka extension telephone terminal 20, 21. It is an instruction to make perceptual settings for etc.
The communication unit 12 inputs the emergency start prohibition instruction sent by the communication unit 32, and outputs this emergency call prohibition instruction to the Tokyo extension telephone terminal 10 (step S6).

When the Tokyo extension telephone terminal 10 inputs the emergency call prohibition instruction, it sets the emergency call prohibition perception setting (step S7).
In addition, the emergency call disable perceptual setting is a setting that allows the user of the Tokyo extension telephone terminal 10 to recognize that the call cannot be made even if he calls the emergency number. This refers to setting up things that are perceived through displays, sounds, vibrations, etc.
On the other hand, in step S4, if the registration control unit 31B determines that the global IP address and the registered global IP address match, the registration control unit 31B selects one of the local IP addresses of the Tokyo extension telephone terminal 10 included in the registration request sent by the communication unit 12. The network address section is extracted, and it is determined whether the network address section and the registered network address section stored in the storage section 33 match (step S8).

When the registration control unit 31B determines that the network address part and the registered network address part do not match (step S8: No), the registration control unit 31B transmits an emergency call prohibition instruction to the communication unit 12 via the communication unit 32 (step S9). .
The communication unit 12 inputs the emergency call prohibition instruction and outputs the emergency call prohibition instruction to the Tokyo extension telephone terminal 10 (step S10).
When the Tokyo extension telephone terminal 10 receives the emergency call prohibition instruction, it sets the emergency call prohibition perception setting (step S11).

Further, in step S8, if the registration control unit 31B determines that the network address part and the registered network address part match (step S8: Yes), it transmits an emergency call permission instruction to the communication unit 12 via the communication unit 32. (Step S12).
The emergency call permission instruction is an instruction sent to the Tokyo extension telephone terminals 10 and 11 and the Osaka extension telephone terminals 20 and 21 in order to inform the user that the telephone number is set to connect when a call is made to the emergency number. Give instructions to perform perceptual settings.
The communication unit 12 inputs the emergency call permission instruction and outputs the emergency call permission instruction to the Tokyo extension telephone terminal 10 (step S13).
When the Tokyo extension telephone terminal 10 receives the emergency call permission instruction, it performs emergency call permission perception setting (step S14).
In addition, the emergency call permission perceptual setting is a display using, for example, text, diagrams, or lights, so that the user of the Tokyo extension telephone terminal 10 can perceive that the call is set to be connected when calling an emergency number. This refers to setting up things that are perceived by sound or vibration.

In this embodiment, as a specific processing flow, in step S4, the registration control unit 31B inputs the input global IP address "0.0.0.15" and the registered global IP address "0.0.0.15". It is determined that they match, and the process proceeds to step S8. Then, in step S8, the registration control unit 31B determines that the network address part "0.0.2" of the input local IP address matches the registered network address part "0.0.20", and in step In S14, the Tokyo extension telephone terminal 10 performs an emergency call permission perception setting.
Although the registration process from the Tokyo head office communication system 100 to the cloud PBX server 30 has been described here, the registration process from the Osaka branch communication system 200 to the cloud PBX server 30 is the same as the above-mentioned registration process, and will be described here. Detailed explanation will be omitted.
Note that the same registration process as described above is performed between the Osaka extension telephone terminals 20 and 21 and the registration control section 31B via the communication section 22 and the communication section 32.

Next, the transmission processing in the communication management system 1 and the cloud PBX server 30 will be explained.
FIG. 3 is a sequence diagram showing the flow of a call process from the Tokyo head office communication system 100 to the cloud PBX server 30.
Note that, similar to the above-described registration process, user identification information, an emergency number, a registered global IP address, and a registered network address section are stored in advance in the storage unit 33 of the cloud PBX server 30 by the cloud PBX service provider.
In addition, the registration process from the Tokyo head office communication system 100 to the cloud PBX server 30 has been completed, and the communication control unit 31A allows the Tokyo head office communication system 100 and the Osaka branch communication system 200 to communicate with the outside line telephone terminal at any time. Assume that you remain online.
Furthermore, since the flow of the call processing using the Tokyo extension telephone terminals 10 and 11 is the same, only the flow of the call processing using the Tokyo extension telephone terminal 10 will be described here.

First, the user operates the Tokyo extension telephone terminal 10 to make a call to a predetermined number. Then, the Tokyo extension telephone terminal 10 transmits a call request to the communication department 12 via the in-house LAN (step S21). This call request includes call request information, the telephone number of the other party, and the local IP address set in the Tokyo extension telephone terminal 10 itself. This local IP address is set to, for example, "0.0.1.10" and includes a network address part "0.0.1". Further, the telephone number of the other party is, for example, "110".
Upon inputting the call request, the communication unit 12 transmits the call request to the cloud PBX server 30 via the Internet (step S22). This call request includes call request information, the telephone number of the other party, the local IP address of the Tokyo extension telephone terminal 10, and the global IP address set in the communication section 12 itself. This global IP address is set to, for example, "0.0.0.15".

The communication unit 32 of the cloud PBX server 30 receives the call request and outputs it to the control unit 31 . When the communication control unit 31A receives the call request, it determines whether or not it is an emergency call (step S23). That is, the communication control unit 31A extracts the telephone number of the other party included in the input call request, reads out the emergency number stored in the storage unit 33, and determines whether the telephone number of the other party and the emergency number match. Determine whether or not. If the communication control unit 31A determines that they do not match (step S23: No), it transmits a call request instruction to the communication unit 12 via the communication unit 32 (step S24). In this case, the communication control unit 31A determines that the call is not an emergency call, and processes the call as a regular call.
When the communication unit 12 receives the call request instruction, it outputs the call request instruction to the telephone communication unit 13 (step S25). When the telephone communication unit 13 receives the call request instruction outputted by the communication unit 12, it performs processing for issuing a call request (step S26). That is, the telephone communication unit 13 transmits a call request to the outside line telephone terminal, and causes a call to be made between the Tokyo extension telephone terminal 10 and the outside line telephone terminal.

On the other hand, in step S23, if the communication control unit 31A determines that the destination telephone number and the emergency number match (step S23: Yes, it is determined that the emergency number is an emergency number), the communication control unit 31A includes the telephone number included in the call request transmitted by the communication unit 12. A global IP address is extracted, and it is determined whether the global IP address matches the registered global IP address stored in the storage unit 33 (step S27). If the communication control unit 31A determines that they do not match (step S27: No), it performs a disconnection process to restrict the call request without issuing a call request instruction (step S28, restriction control step). At this time, the communication control unit 31A transmits an emergency call impossibility perception instruction to the communication unit 12 via the communication unit 32, and sets the perception setting to make it perceivable that an emergency call is not possible through display, sound, vibration, etc. The extension telephone terminal 10 may be made to do this.

On the other hand, in step S27, if the communication control unit 31A determines that the global IP address and the registered global IP address match (step S27: Yes), the communication control unit 31A determines that the global IP address and the registered global IP address match (step S27: Yes). It is determined whether the network address part of the local IP address matches the registered network address part stored in the storage section 33 (step S29).
If the communication control unit 31A determines that the network address part and the registered network address part match (step S29: Yes), the communication control unit 31A transmits a call request instruction to the communication unit 12 via the communication unit 32 (step S30).
Similarly to the above, the communication unit 12 receives the call request instruction and outputs the call request instruction to the telephone communication unit 13 (step S31). The telephone communication unit 13 performs the same calling process as described above (step S32).
Further, in step S29, if the communication control unit 31A determines that the network address part and the registered network address part do not match (step S29: No), it performs the same disconnection process as described above (step S33, the second regulatory control step). At this time, the communication control unit 31A transmits an emergency call impossibility perception instruction to the communication unit 12 via the communication unit 32, and sets the perception setting to make it perceivable that an emergency call is not possible through display, sound, vibration, etc. The extension telephone terminal 10 may be made to do this.

In this embodiment, as a specific process flow, the communication control unit 31A determines in step S23 that the destination phone number "110" matches the emergency call stored in the storage unit 33 (step S23: Yes). In step S27, it is determined that the global IP address "0.0.0.15" and the registered global IP address "0.0.0.15" match (step S27: Yes), and in step S29, the network address section " 0.0.1" and the registered network address section "0.0.1" match (step S29: Yes), and causes the telephone communication section 13 to perform a calling process (step S32). That is, the Tokyo extension telephone terminal 10 can make an emergency call to the nearest police station within the area.

Further, for example, when the Osaka extension phone terminal 20 makes a call to a normal destination phone number and sends a call request instruction to the cloud PBX server 30 via the communication unit 22, the communication control unit 31A A call request instruction is transmitted to the communication unit 12 of the system 100, and the telephone communication unit 13 performs the calling process. In this case, from the point of view of the other party's outside line telephone terminal, even if the call is made from Osaka, it will be the same as if the call was made from the Tokyo head office communication system 100. Therefore, conventionally, there is a problem in that when an emergency call is made from Osaka, the call is made to the nearest police station or the like of the Tokyo head office communication system 100.
On the other hand, even if, for example, the Osaka extension telephone terminal 20 directly sends an emergency call request to the cloud PBX server 30 via the communication unit 22, the communication control unit 31A does not respond to the communication unit 22's global IP address “0.0. It is determined that the registered global IP address "0.25" and the registered global IP address "0.0.0.15" do not match (step S27: No), and a disconnection process is performed (step S28). Therefore, even if an emergency call is made from Osaka, it is prevented that the call is made to the nearest Tokyo police station to the Tokyo head office communication system 100. In this case, even without the process of determining whether the network address portions match (step S29), just by determining whether the global IP addresses match, an emergency call from Osaka to Tokyo can be prevented.

However, as in this embodiment, when the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via a VPN (Virtual Private Network), calls from the communication unit 22 of the Osaka branch communication system 200 The request will not be sent directly to the cloud PBX server 30, but will be sent via the communication unit 12 of the Tokyo head office communication system 100. Then, when an emergency call is made from Osaka, the communication control unit 31A recognizes the global IP address “0.0.0.15” sent from the communication unit 12 and the registered global IP address “0.0.0.15.” If it is determined that they match (step S27: Yes), and there is no process to determine whether the network address parts match (step S29), an emergency call will be made to Tokyo.
In this embodiment, even if the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via a VPN (Virtual Private Network), as shown in the Osaka transmission flow shown in FIG. This prevents outgoing calls from being sent to Tokyo.

FIG. 4 shows cloud communication from the Osaka branch communication system 200 through the communication unit 12 of the Tokyo head office communication system 100 when the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via a VPN (Virtual Private Network). FIG. 3 is a sequence diagram showing the flow of outgoing call processing to the PBX server 30. FIG.
Note that since the Osaka originating flow shown in FIG. 4 is basically the same as the Tokyo originating flow shown in FIG. 3, the same flows are denoted by the same reference numerals, and the different processes will be mainly explained here.
First, the user operates the Osaka extension telephone terminal 20 to make a call to a predetermined number. Then, the Osaka extension telephone terminal 20 transmits a call request to the communication department 22 via the in-house LAN (step S41). This call request includes call request information, the telephone number of the other party, and the local IP address set in the Osaka extension telephone terminal 20 itself. This local IP address is set to, for example, "0.0.2.20" and includes a network address part "0.0.2". Further, the telephone number of the other party is, for example, "110".

When the communication unit 22 receives the call request, it transmits the call request to the communication unit 12 via a VPN (Virtual Private Network) (step S42). This call request includes call request information, the telephone number of the other party, the local IP address of the Osaka extension telephone terminal 20, and the global IP address set in the communication unit 22 itself. This global IP address is set to, for example, "0.0.0.25".
When the communication unit 12 receives the call request transmitted by the communication unit 22, the communication unit 12 transmits the call request to the cloud PBX server 30 via the Internet (step S43). This call request includes call request information, the telephone number of the other party, the local IP address of the Osaka extension telephone terminal 20, and the global IP address set in the communication unit 12 itself. This global IP address is set to, for example, "0.0.0.15".

After that, the communication management system 1 performs the processes from steps S23 to S33 in the same manner as described above.
In this embodiment, as a specific process flow, the communication control unit 31A determines in step S23 that the destination phone number "110" matches the emergency call stored in the storage unit 33 (step S23: Yes). In step S27, it is determined that the global IP address "0.0.0.15" and the registered global IP address "0.0.0.15" match (step S27: Yes), and in step S29, the network address section "0.0.2" and the registered network address part "0.0.1" do not match (step S29: No), and performs a disconnection process (step S33).
On the other hand, when a call is made from the Osaka extension telephone terminal 20 to a normal destination phone number instead of an emergency call, the communication control unit 31A checks the destination phone number and the emergency call stored in the storage unit 33 in step S23. It is determined that they do not match (step S23: No), and the telephone communication unit 13 is caused to perform a calling process (step S26).
That is, when you make a call from the Osaka extension telephone terminal 20 to the telephone number of the normal telephone number, you can make a call to the external telephone terminal via the telephone communication section 13. A call request can only be disconnected when calling a phone number.

As described above, according to the communication management system 1 and the cloud PBX server 30 in this embodiment, the communication control unit 31A controls the global When the IP address and the registered global IP address stored in the storage unit 33 do not match, call requests are restricted. Therefore, even if an emergency call is made from a telephone terminal located so far away that the jurisdiction of the emergency destination is different, the telephone communication section 13 is installed in the same area as the communication section 12. This prevents calls from being made to emergency destinations in the jurisdiction. Therefore, an emergency call request can be appropriately processed.
In addition, when the call request from the communication unit 12 is an emergency call request, the communication control unit 31A determines that the global IP address sent from the communication unit 12 and the registered global IP address match, and When the network address part of the local IP address of the Tokyo extension telephone terminal 10, 11 or Osaka extension telephone terminal 20, 21 does not match the registered network address part stored in the storage part 33, call requests are restricted. Therefore, even if two locations are connected via a VPN (Virtual Private Network) or the like and a call request is sent via the communication section 12 and telephone communication section 13 of one of the locations, the emergency call request cannot be properly handled. can be processed.

In addition, when the registration control unit 31B inputs a registration request transmitted from the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 via the communication units 12, 22, the registration control unit 31B receives a registration request transmitted from the communication units 12, 22. When the global IP address and the registered global IP address stored in the storage unit 33 do not match, the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 are made to set the emergency call impossibility. Therefore, users using the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 can be made aware in advance that emergency calls cannot be made.
In addition, when the registration control unit 31B inputs a registration request transmitted from the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 via the communication units 12, 22, the registration control unit 31B receives a registration request transmitted from the communication units 12, 22. If the global IP address and the registered global IP address stored in the storage unit 33 match, and the local IP address of the Tokyo extension telephone terminal 10, 11 or the Osaka extension telephone terminal 20, 21 is transmitted from the communication unit 12, 22, When the network address part and the registered network address part stored in the storage part 33 match, the Tokyo extension telephone terminal 10, 11 or the Osaka extension telephone terminal 20, 21 is made to perform emergency call permission perception setting. Therefore, users using the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 can be made aware in advance that an emergency call is possible.

Note that the technical scope of the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention.
For example, although the communication control unit 31A determines whether the global IP address and the registered global IP address match, this function may not be provided. In that case, the communication control unit 31A may determine whether the network address part and the registered network address part match.
Furthermore, although the communication control section 31A determines whether the network address section and the registered network address section match, this function may not be provided. In that case, the communication control unit 31A may determine whether the global IP address and the registered global IP address match.
That is, the communication control unit 31A determines whether the global IP address and the registered global IP address match, and determines whether the network address part and the registered network address part match, but the invention is not limited to this. Instead, at least one of them may be determined.

Further, although it is stated that the communication control unit 31A determines whether the global IP address and the registered global IP address match, and then determines whether the network address part and the registered network address part match, the invention is limited to this. You can change the order of these. That is, the communication control unit 31A may determine whether the network address section and the registered network address section match, and then determine whether the global IP address and the registered global IP address match. A specific flow of the start processing in this case is shown in FIG. In FIG. 5, since the processing is the same as in FIG. 3, all the symbols are the same and the explanation thereof will be omitted. However, the order of step S27 and step S29 is switched. That is, the communication control unit 31A determines whether the network address part and the registered network address part match (step S29), and if it determines that they do not match (step S29: No), performs a disconnection process (step S28). ). On the other hand, if the communication control unit 31A determines that the network address part and the registered network address part match (step S29: Yes), it determines whether the global IP address and the registered global IP address match (step S27), If it is determined that they do not match (step S27: No), a cutting process is performed (step S33).
Further, the communication control unit 31A determines whether it is an emergency call, determines whether the global IP address matches the registered global IP address, and determines whether the network address part and the registered network address part match. However, the present invention is not limited to this, and the telephone communication section 13 may perform at least one of these functions. For example, the fixed telephone gateway included in the telephone communication section 13 may perform the processing. In this case, the telephone communication unit 13 functions as a communication management device. Furthermore, the communication unit 12 may perform at least one of the above-mentioned functions. In this case, the communication unit 12 functions as a communication management device. Furthermore, the above-mentioned functions may be distributed to any one of the communication control section 31A, the communication section 12, or the telephone communication section 13. Further, it goes without saying that the modification of the communication control section 31A described above can also be applied to the communication section 12 and the telephone communication section 13.

It is also stated that the registration control unit 31B determines whether the global IP address and the registered global IP address match, and also determines whether the network address part and the registered network address part match, but this function is not provided. You don't have to. In that case, it is not necessary to perform the emergency call prohibition perception setting and the emergency call permission perception setting.
Further, the registration control unit 31B determines whether the global IP address and the registered global IP address match, and also determines whether the network address part and the registered network address part match, but at least one of them may be determined.
Furthermore, although the registration control unit 31B causes the emergency call disable percept setting and the emergency call permission percept setting, the present invention is not limited to this, and at least one of them may be performed.
Further, although it is stated that the registration control unit 31B determines whether the global IP address and the registered global IP address match, and then determines whether the network address part and the registered network address part match, the invention is limited to this. You can change the order of these. That is, the registration control unit 31B may determine whether the network address part and the registered network address part match, and then determine whether the global IP address and the registered global IP address match. That is, in FIG. 5, steps S4 and S8 in FIG. 2 may be interchanged in the same way as steps S27 and S29 in FIG. 3 are interchanged.

Further, although it is assumed that Tokyo extension telephone terminals 10 and 11 or Osaka extension telephone terminals 20 and 21 are installed, the number of extension telephone terminals installed can be changed as appropriate.
Furthermore, the settings of the global IP address, local IP address, network address section, and host section can be changed as appropriate.
Further, although the registered global IP address stored in the storage unit 33 is the global IP address of the communication unit 12, it is not limited to this, and may be a global IP address of the telephone communication unit 13 such as a fixed telephone gateway, for example. Good too.
Furthermore, although the communication section 12 transmits the local IP addresses of the Tokyo extension telephone terminals 10 and 11 or the Osaka extension telephone terminals 20 and 21, the present invention is not limited to this, and the network address section may also be transmitted.
Further, although the storage unit 33 is described as storing a network address part, the storage unit 33 is not limited to this, and may also store a local IP address.
