(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). The Tokyo head office communication system 100, the Osaka branch communication system 200, and the cloud PBX server 30 are connected via a network such as the Internet. 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, each having 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".
A local IP address consists 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, "0.0.1" from the left end is set as the network address part, and "10" at 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 for transmitting and receiving information to and from internal devices and external devices, such as 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 (shown as “GIP” in the figure) is set in the communication unit 12 . The global IP address of the communication unit 12 is set to "0.0.0.15", for example. The communication section 12 is connected to the telephone communication section 13 .
The telephone communication unit 13 is composed of various communication devices for transmitting and receiving information between the Tokyo extension telephone terminals 10 and 11 and the external telephone terminals, and is composed of, for example, a fixed telephone gateway and an ONU (Optical Network Unit). The telephone communication unit 13 is installed in the same area as the area where the communication unit 12 is installed, and makes a call between the Tokyo extension telephone terminals 10 and 11 and the outside telephone terminal.

The Osaka branch communication system 200 includes Osaka extension telephone terminals 20 and 21 (telephone terminals), a communication unit 22 and a telephone communication unit 23 .
The Osaka extension telephone terminals 20 and 21 are, for example, IP telephones, each of which has 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".
In this embodiment, for example, of the local IP address of the Osaka extension telephone terminal 20, "0.0.2" from the left end is set as the network address part, and "20" at 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 for transmitting and receiving information to and from internal devices and external devices, such as 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 "0.0.0.25", for example. The communication section 22 is connected to the telephone communication section 23 .
The telephone communication unit 23 consists of various communication devices for transmitting and receiving information between the Osaka extension telephone terminals 20 and 21 and the outside telephone terminals, for example, a fixed telephone gateway and an ONU. The telephone communication unit 23 is installed in the same area as the area where the communication unit 22 is installed, and makes a call 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 makes calls on the Internet, and is realized by, for example, a computer functioning as a server. The cloud PBX server 30 includes a control section 31 , a communication section 32 and a storage section 33 .
The control unit 31 is realized by, for example, arithmetic means such as a processor and a CPU, functions in cooperation with storage means such as various memories and hard disks, and executes various programs.
The control unit 31 includes a communication control unit 31A (regulation control unit) and a registration control unit 31B.

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

When a registration request is input from the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21, the registration control section 31B determines whether or not the global IP address transmitted from the communication section 12 matches the registered global IP address stored in the storage section 33. When the registration control unit 31B determines that the 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 transmitted the registration request to set emergency call impossibility, which will be described later. When the registration control unit 31B determines that the global IP addresses match, the registration control unit 31B determines whether the network address part of the local IP address of the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21 transmitted from the communication unit 12 matches the registered network address part stored in the storage unit 33. If it determines that they do not match, the registration control unit 31B makes the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 that have transmitted the registration request perform the emergency call disable perception setting. . Further, when the registration control unit 31B determines that the global IP addresses match, and determines that the network address part matches, the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 that have transmitted the registration request are made to perform emergency call permission perception settings, which will be described later.

The communication unit 32 includes various communication devices for transmitting and receiving information to and from internal devices and external devices. The communication unit 32 inputs the local IP address and the 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 emergency call permission instruction from the registration control unit 31B.
The storage unit 33 is composed of, for example, a hard disk or memory, and stores various programs, work data, and the like. The storage unit 33 also stores an emergency number, a global IP address and a network address part. That is, the registration control unit 31B pre-stores the emergency number in the storage unit 33 by a storage operation by the cloud PBX service provider. Further, the registration control unit 31B automatically stores the global IP address and the network address part in the storage unit 33 in advance.
An 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 permits an emergency call request is set, and the address that is stored in the storage unit 33 after the emergency call request is permitted 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 section is set to permit an emergency call request, and the address stored in the storage section 33 after the emergency call request is permitted becomes the registered network address section. For example, "0.0.1" is stored as the registered network address field. The registered network address section here is the network address section within the communication system 100 at the Tokyo head office.

Next, registration processing in the communication management system 1 and the cloud PBX server 30 will be described.
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. As shown in FIG.
Note that the storage unit 33 of the cloud PBX server 30 stores user identification information, emergency numbers, registered global IP addresses, and registered network address units in advance by the cloud PBX service provider.
User identification information is information for identifying users who can use the cloud PBX service provided by the cloud PBX server 30, and includes, for example, user IDs and passwords.
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 part, for example, the network address part "0.0.1" of the local IP address "0.0.1.10" in the communication system 100 of the Tokyo head office is stored.

Since the flow of registration processing 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 it in the cloud PBX server 30 . That is, the Tokyo extension telephone terminal 10 transmits a registration request to the communication section 12 via the company LAN (step S1). This registration request includes user identification information, registration request information, 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".
After inputting 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 in 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 outputs the registration request to the control unit 31 when inputting the registration request. The registration control unit 31B receives the registration request and performs registration processing (step S3). That is, the registration control unit 31B determines whether or not the input user identification information is stored in the storage unit 33, and if it determines that it is stored, outputs a communication permission instruction to the communication control unit 31A. The communication control unit 31A maintains the online state so that the Tokyo head office communication system 100 and the Osaka branch communication system 200 can always communicate with the external telephone terminal. On the other hand, when the registration control section 31B determines that the input user identification information is not stored in the storage section 33, it causes the Tokyo extension telephone terminal 10 to display the non-registration information via the communication section 12. FIG.

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 transmitted by the communication unit 12, and determines whether the global IP address matches the registered global IP address stored in the storage unit 33 (step S4). If the registration control unit 31B determines that they do not match (step S4: No), the registration control unit 31B 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 disapproval instruction to, for example, the display unit of the cloud PBX server 30 to display that the emergency call is not possible on the management interface of the display unit. It should be noted that the setting of perception may be something other than display, as will be described later.
Note that the emergency start prohibition instruction is an instruction to make the Tokyo extension telephone terminals 10, 11 and the Osaka extension telephone terminals 20, 21, etc. perform perceptual settings in order to inform the user, etc. that the telephone is set to be unreachable even if a call is made to the emergency number.
The communication unit 12 receives the emergency start prohibition instruction transmitted 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, the emergency call prohibition perception setting is performed (step S7).
Note that the emergency call impossibility perception setting means that the user of the Tokyo extension telephone terminal 10 can perceive that the phone is not connected even if the emergency number is dialed.
On the other hand, when the registration control unit 31B determines in step S4 that the global IP address and the registered global IP address match, it extracts the network address part of the local IP address of the Tokyo extension telephone terminal 10 included in the registration request transmitted by the communication part 12, and determines whether the network address part matches the registered network address part stored in the storage unit 33 (step S8).

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

Also, in step S8, when 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 to make the Tokyo extension telephone terminals 10 and 11 and the Osaka extension telephone terminals 20 and 21 perform perceptual setting in order to inform the user that the telephone is set to be connected by making a call to the emergency number.
The communication unit 12 receives the emergency call permission instruction and outputs the emergency call permission instruction to the Tokyo extension telephone terminal 10 (step S13).
When the emergency call permission instruction is input, the Tokyo extension telephone terminal 10 performs emergency call permission perception setting (step S14).
Note that the emergency call permission perception setting refers to a setting that allows the user of the Tokyo extension phone terminal 10 to perceive that the phone is set to be connected when calling an emergency number, for example, by displaying characters, charts, or light, or by sound or vibration.

In this embodiment, as a specific processing flow, in step S4, the registration control unit 31B determines that the input global IP address "0.0.0.15" matches the registered global IP address "0.0.0.15", and 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 S14, the Tokyo extension telephone terminal 10 performs 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-described registration process, and detailed description is omitted here.
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. FIG.

Next, call processing in the communication management system 1 and the cloud PBX server 30 will be described.
FIG. 3 is a sequence diagram showing the flow of call processing from the Tokyo head office communication system 100 to the cloud PBX server 30. As shown in FIG.
As in the registration process described above, the storage unit 33 of the cloud PBX server 30 stores user identification information, an emergency number, a registered global IP address, and a registered network address in advance by the cloud PBX service provider.
In addition, the registration processing from the Tokyo head office communication system 100 to the cloud PBX server 30 has been completed, and 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 the outside line telephone terminal at any time.
In addition, since the flow of calling processing using the Tokyo extension telephone terminals 10 and 11 is the same, only the calling processing flow 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 section 12 via the company LAN (step S21). This call request includes call request information, the other party's telephone number, 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 the network address part "0.0.1". Also, the other party's telephone number is, for example, "110".
Upon receiving 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 other party's telephone number, the local IP address of the Tokyo extension telephone terminal 10, 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".

The communication unit 32 of the cloud PBX server 30 outputs the call request to the control unit 31 when inputting the call request. When receiving the call request, the communication control unit 31A determines whether the call is an emergency call (step S23). That is, the communication control unit 31A extracts the destination telephone number included in the input call request, reads the emergency number stored in the storage unit 33, and determines whether or not the destination telephone number and the emergency number match. When 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 it as a normal call.
When receiving the call request instruction, the communication section 12 outputs the call request instruction to the telephone communication section 13 (step S25). When the telephone communication unit 13 receives the call request instruction output by the communication unit 12, the telephone communication unit 13 performs call request origination processing (step S26). That is, the telephone communication unit 13 transmits a call request to the outside line telephone terminal, and makes a call between the Tokyo extension telephone terminal 10 and the outside line telephone terminal.

On the other hand, when the communication control unit 31A determines in step S23 that the telephone number of the other party matches the emergency number (step S23: Yes, determines that it is an emergency number), the communication control unit 31A extracts the global IP address included in the call request sent by the communication unit 12, and determines whether the global IP address matches the registered global IP address stored in the storage unit 33 (step S27). When the communication control unit 31A determines that they do not match (step S27: No), the communication control unit 31A performs disconnection processing to regulate the call request without issuing a call request instruction (step S28, regulation control step). At this time, the communication control unit 31A may transmit an emergency call impossibility perception instruction to the communication unit 12 via the communication unit 32, and cause the Tokyo extension telephone terminal 10 to perform a perception setting to perceive the emergency call impossibility by display, sound, vibration, or the like.

On the other hand, when the communication control unit 31A determines in step S27 that the global IP address and the registered global IP address match (step S27: Yes), it determines whether the network address part of the local IP address of the Tokyo extension telephone terminal 10 included in the call request sent by the communication part 12 matches the registered network address part stored in the storage unit 33 (step S29).
When the communication control section 31A determines that the network address section and the registered network address section match (step S29: Yes), the communication control section 31A transmits a call request instruction to the communication section 12 via the communication section 32 (step S30).
As described above, the communication section 12 receives the call request instruction and outputs the call request instruction to the telephone communication section 13 (step S31). The telephone communication unit 13 performs the outgoing call process similar to that described above (step S32).
Further, in step S29, when the communication control unit 31A determines that the network address part and the registered network address part do not match (step S29: No), the same disconnection process as described above is performed (step S33, second regulation control step). At this time, the communication control unit 31A may transmit an emergency call impossibility perception instruction to the communication unit 12 via the communication unit 32, and cause the Tokyo extension telephone terminal 10 to perform a perception setting to perceive the emergency call impossibility by display, sound, vibration, or the like.

In this embodiment, as a specific processing flow, the communication control unit 31A determines that the destination telephone number "110" matches the emergency call stored in the storage unit 33 in step S23 (step S23: Yes), determines that the global IP address "0.0.0.15" matches the registered global IP address "0.0.0.15" in step S27 (step S27: Yes), and determines that the network address part "0.0.0.15" matches in step S29. 1” matches the registered network address portion “0.0.1” (step S29: Yes), and causes the telephone communication section 13 to perform call processing (step S32). That is, the Tokyo extension telephone terminal 10 can make an emergency call to the nearest police station in the area.

Also, for example, when the Osaka extension telephone terminal 20 makes a call to a normal destination telephone number and transmits a call request instruction to the cloud PBX server 30 via the communication unit 22, the communication control unit 31A transmits the call request instruction to the communication unit 12 of the Tokyo head office communication system 100, and the telephone communication unit 13 performs call processing. In this case, from the outside line telephone terminal of the other party, even if the call is made from Osaka, it is the same as if the call is made from the communication system 100 at the head office of Tokyo. Therefore, conventionally, when an emergency call is made from Osaka, there is a problem that the call is sent to the nearest police station or the like of the communication system 100 at the Tokyo head office.
On the other hand, for example, even if the Osaka extension telephone terminal 20 directly transmits an emergency call request to the cloud PBX server 30 via the communication unit 22, the communication control unit 31A determines that the global IP address “0.0.0.25” of the communication unit 22 does not match the registered global IP address “0.0.0.15” (step S27: No), and performs disconnection processing (step S28). Therefore, it is possible to prevent an emergency call from Osaka from being sent to the police station in Tokyo nearest to the communication system 100 of the Tokyo head office. In this case, even if there is no process (step S29) for determining whether the network address part matches, it is possible to prevent an emergency call from Osaka to be made to Tokyo simply by determining whether the global IP address matches.

However, when the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via VPN (Virtual Private Network) as in the present embodiment, the call request from the communication unit 22 of the Osaka branch communication system 200 is not directly sent to the cloud PBX server 30, but is 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 determines that the global IP address "0.0.0.15" transmitted from the communication unit 12 matches the registered global IP address "0.0.0.15" (step S27: Yes).
In the present embodiment, as shown in the Osaka call origination flow shown in FIG. 4, even if the Tokyo head office communication system 100 and the Osaka branch communication system 200 are connected via a VPN (Virtual Private Network), emergency calls from Osaka are prevented from being sent to Tokyo.

FIG. 4 is a sequence diagram showing the flow of call processing from the Osaka branch communication system 200 to the cloud PBX server 30 via 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).
4 is basically the same as the Tokyo origination flow shown in FIG. 3, the same reference numerals are used for the same flow, and different processing will be mainly described 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 section 22 via the company LAN (step S41). This call request includes call request information, the other party's telephone number, 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 the network address part "0.0.2". Also, the other party's telephone number is, for example, "110".

When receiving the call request, the communication unit 22 transmits the call request to the communication unit 12 via VPN (Virtual Private Network) (step S42). This call request includes call request information, the other party's telephone number, 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 receiving 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 other party's telephone number, 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 processing flow, the communication control unit 31A determines that the destination telephone number "110" matches the emergency call stored in the storage unit 33 in step S23 (step S23: Yes), determines that the global IP address "0.0.0.15" matches the registered global IP address "0.0.0.15" in step S27 (step S27: Yes), and determines that the network address part "0.0.0.15" matches in step S29. 2” does not match the registered network address part “0.0.1” (step S29: No), and the disconnection process is performed (step S33).
On the other hand, when a call is made from the Osaka extension telephone terminal 20 to a normal destination telephone number instead of an emergency, the communication control unit 31A determines in step S23 that the destination telephone number and the emergency call stored in the storage unit 33 do not match (step S23: No), and causes the telephone communication unit 13 to perform call processing (step S26).
Namely, when the Osaka extension telephone terminal 20 makes a call to the normal telephone number of the other party, the call can be made with the outside telephone terminal through the telephone communication part 13, and the call request can be disconnected only when the Osaka extension telephone terminal 20 makes a call to the urgent telephone number of the other party.

As described above, according to the communication management system 1 and the cloud PBX server 30 in the present embodiment, when the call request from the communication unit 12 is an emergency call request, the communication control unit 31A regulates the call request when the global IP address transmitted from the communication unit 12 and the registered global IP address stored in the storage unit 33 do not match. Therefore, even if an emergency call is made from a telephone terminal located in a remote location so that the jurisdiction of the emergency party is different via the telephone communication section 13 installed in the same area as the communication section 12, the emergency party under the jurisdiction of the telephone communication section 13 is prevented from being called. Therefore, an urgent call request can be appropriately processed.
Further, when the call request from the communication unit 12 is an emergency call request, the communication control unit 31A regulates the call request when the global IP address transmitted from the communication unit 12 matches the registered global IP address and when the network address part of the local IP address of the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 transmitted from the communication unit 12 does not match the registered network address part stored in the storage unit 33. Therefore, even when two bases are connected by a VPN (Virtual Private Network) or the like and a call request is transmitted via the communication unit 12 and the telephone communication unit 13 of one base, an emergency call request can be appropriately processed.

Further, when a registration request transmitted from the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 via the communication sections 12, 22 is inputted, the registration control section 31B causes the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 to set the emergency call impossibility perception when the global IP address transmitted from the communication sections 12, 22 does not match the registered global IP address stored in the storage section 33. Therefore, users using the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 can be made to perceive in advance that an emergency call cannot be made.
When registration control unit 31B inputs a registration request transmitted from Tokyo extension telephone terminals 10, 11 or Osaka extension telephone terminals 20, 21 via communication units 12, 22, registration control unit 31B matches the global IP address transmitted from communication units 12, 22 with the registered global IP address stored in storage unit 33, and registers the network address part of the local IP address of Tokyo extension telephone terminals 10, 11 or Osaka extension telephone terminals 20, 21 transmitted from communication units 12, 22. When the registered network address part stored in the storage part 33 matches, the Tokyo extension telephone terminals 10, 11 or the Osaka extension telephone terminals 20, 21 are made to set the emergency call permission perception. 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 can be made.

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope 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 section 31A may determine whether the network address section and the registered network address section match.
Also, 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.
In other words, 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.

In addition, 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. That is, the communication control unit 31A may determine whether the network address portion and the registered network address portion match, and then determine whether the global IP address and the registered global IP address match. FIG. 5 shows a flow of a concrete starting process in this case. In FIG. 5, since the processing is the same as in FIG. 3, all the reference numerals are the same and the description thereof is omitted. However, the order of step S27 and step S29 is changed. 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 disconnection processing (step S28). On the other hand, when 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).
Further, the communication control unit 31A determines whether the call is an emergency call, determines whether the global IP address matches the registered global IP address, and determines whether the network address part matches the registered network address part. For example, a fixed telephone gateway included in the telephone communication unit 13 may perform this. In this case, the telephone communication section 13 functions as a communication management device. Furthermore, at least one of the functions described above may be performed by the communication unit 12 . In this case, the communication section 12 functions as a communication management device. Further, the functions described above may be distributed to either the communication control section 31A, the communication section 12 or the telephone communication section 13. FIG. 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. FIG.

Also, the registration control unit 31B 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 this function does not have to be provided. In that case, the emergency call impossibility perception setting and the emergency call permission perception setting need not be performed.
Further, although the registration control unit 31B 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, at least one of them may be determined.
Further, although the registration control unit 31B makes the emergency call impossibility perception setting and the emergency call permission perception setting, the present invention is not limited to this, and at least one of them may be made.
Further, 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. That is, the registration control unit 31B may determine whether the network address portion and the registered network address portion 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 that steps S27 and S29 in FIG. 3 are interchanged.

Also, although the Tokyo extension telephone terminals 10 and 11 or the Osaka extension telephone terminals 20 and 21 are installed, the number of extension telephone terminals installed can be changed as appropriate.
Also, the settings of the global IP address, local IP address, network address part, and host part can be changed as appropriate.
Also, 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 the global IP address of the telephone communication unit 13 such as a fixed telephone gateway.
Also, although the communication unit 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 portion may be transmitted.
Also, although the storage unit 33 stores the network address portion, the storage unit 33 is not limited to this, and may store a local IP address.

In addition, each of the above-described functional units constituting the Tokyo head office communication system 100, the Osaka branch communication system 200, and the cloud PBX server 30 may be provided in a single computer, or may be distributed to a plurality of computers capable of communicating via a communication network.
Also, a program for realizing the functions of the communication management system 1 and the cloud PBX server 30 may be recorded in a computer-readable recording medium, and the computer system may read and execute the program recorded in the recording medium to perform various processes. It should be noted that the "computer system" referred to here includes hardware such as an OS and peripheral devices.

The "computer system" also includes the home page providing environment (or display environment) if the WWW system is used.
In addition, "computer-readable recording medium" refers to portable media such as hard disks, flexible disks, magneto-optical disks, ROMs, CD-ROMs, DVDs, USB (registered trademark) memories, and storage devices such as hard disks built into computer systems. Furthermore, the term "computer-readable recording medium" includes media that dynamically retain programs for a short period of time, such as communication lines for transmitting programs via networks such as the Internet and communication lines such as telephone lines, and media that retain programs for a certain period of time, such as volatile memory inside a computer system that serves as a server or client. Further, the program may be for realizing part of the functions described above, or may be capable of realizing the functions described above in combination with a program already recorded in the computer system.
