Description

  The present invention relates to an exchange apparatus, a transfer program, and a transfer method, and can be applied to a private branch exchange apparatus such as an IP-PBX, for example.

  Conventionally, when an extension telephone terminal accommodated in a private branch exchange transfers a call to a telephone terminal of another destination during a call with an external line or another extension telephone terminal, the extension telephone terminal in a call state A hold operation was performed at, and a call was made to the forwarding destination. Also, in the extension state telephone terminal in a call state, the caller number to the transfer destination telephone terminal is either manually entered by the user or automatically dialed by the extension telephone terminal or the private branch exchange (the preset caller's caller number is Functions such as automatic input) and system abbreviated dialing (a function in which a caller ID is automatically input by simply specifying a registered number set in advance by the user).

  Further, in the telephone system described in Patent Document 1, a software phone that realizes call processing, voice signal processing, and the like by software on an information processing device such as a personal computer, and a telephone terminal (hereinafter referred to as “hard phone”) using a hardware device. In other words, operations related to outgoing calls are performed using an address book on a softphone, and calls themselves are performed using a hardphone.

Furthermore, even in a system that can link a hard phone and a soft phone, a system that can transfer by a soft phone operation during a call has fixedly associated the hard phone and the soft phone.

The IP-PBX 10 is a device having an interface for communicating with other communication devices (such as a CPU, ROM, RAM, EEPROM, hard disk, etc.) and a program (not limited to one device). In other words, it is constructed by installing the transfer program of the embodiment or the like.

  The IP-PBX 10 is connected to the public network N and is connected to the telephone terminal 40 via the public network N. The public network N may be, for example, an IP network such as the Internet, or a public telephone network based on a conventional circuit switching system. When the public network N is a public telephone network based on a circuit switching system, the IP-PBX 10 may be separately provided with an interface for connecting to the public telephone network.

  The PC 30 is a soft phone that realizes call processing, voice signal processing, and the like on software on an information processing apparatus such as a personal computer, and functions as an IP telephone terminal accommodated in the IP-PBX 10. In FIG. 1, one PC 30-1 is accommodated in the IP-PBX 10, but the number of PCs 30 accommodated is not limited.

  The extension telephone terminal 20 is an IP telephone terminal accommodated in the IP-PBX 10 and has a hardware configuration. In FIG. 1, the IP-PBX 10 accommodates two extension telephone terminals 20 (20-1, 20-2), but the number of extension telephone terminals 20 accommodated is not limited.

  The telephone terminal 40 is a telephone terminal that connects to the public network N and connects to the IP-PBX 10 via the public network N. The telephone terminal 40 may be a hard phone or a soft phone, and the type of terminal is not limited. Further, although not shown in FIG. 1, the telephone terminal 40 may be a telephone terminal accommodated in another switching device, and the connection method is not limited.

  The IP-PBX 10 has a cooperation information registration unit 11.

  FIG. 2 is an explanatory diagram showing a configuration example of information registered in the cooperation information registration unit 11.

  The link information registration unit 11 is a means for registering the link between the extension telephone terminal 20 and the PC 30 that is accommodated in the IP-PBX 10, and has information on the extension telephone terminal identification information 111 and the soft phone identification information 112. is doing.

  The extension telephone terminal identification information 111 indicates information for identifying the extension telephone terminal 20 in the IP-PBX 10.

  The softphone identification information 112 indicates information for identifying the PC 30 in the IP-PBX 10.

  In the extension telephone terminal identification information 111 and the softphone identification information 112, an extension number assigned in the IP-PBX 10 may be registered, or an IP address or a host name may be registered. The format is not limited as long as the terminal can identify the terminal. In FIG. 2, as an example, the extension telephone terminal identification information 111 is described as registering the extension number of the extension telephone terminal 20, and the softphone identification information 112 is registered as the host name (or IP address) of the PC 30.

  For example, assume that the extension number of the extension telephone terminal 20-1 is “001”, the host name of the PC 30-1 is “PC1”, and the IP address of the PC 30-1 is “aa.bb.cc.01”. . In the cooperation information registration unit 11, when there is information that the extension telephone terminal identification information 111 is “001” and the softphone identification information 112 is “PC1” (or “aa.bb.cc.01”). The extension telephone terminal 20-1 and the PC 30-1 are to be linked.

  In the IP-PBX 10, when the extension telephone terminal 20 is in a call state with another telephone terminal, if an operation of making a call from the PC 30 linked with the extension telephone terminal 20 to the other telephone terminal is performed, the above extension The telephone terminal 20 connects the telephone terminal that is in a call and the telephone terminal that is the destination of the PC 30 to transfer the call. For example, in the cooperation information registration unit 11, when information indicating that the extension telephone terminal 20-1 and the PC 30-1 are registered is registered, the extension telephone terminal 20-1 and the telephone terminal 40-1 are connected and a call is made. In the state, by making a call from the PC 30-1 to the extension telephone terminal 20-2, the IP-PBX 10 transfers the call to the extension telephone terminal 20-2, and the extension telephone terminal 20-2 and the telephone terminal 40- 1 is put into a call state. The information registered in the linkage information registration unit 11 may be registered by the user using a telephone terminal such as the PC 30 or the extension telephone terminal 20.

(A-2) Operation of Embodiment Next, a call transfer operation (transfer method of the embodiment) in the exchange apparatus of the embodiment having the above-described configuration will be described.

  FIG. 3 is a sequence diagram showing a call transfer operation in the exchange apparatus of this embodiment.

  FIG. 3 shows that when the extension telephone terminal 20-1 and the telephone terminal 40-1 are in a call state, the user of the extension telephone terminal 20-1 performs an operation for transferring the call to the extension telephone terminal 20-2. The example of the operation | movement which makes the telephone terminal 40-1 and the extension telephone terminal 20-2 call state is shown.

  Further, the extension number of the extension telephone terminal 20-1 is “001”, and the host name of the PC 30-1 is “PC1”. In the linkage information registration unit 11, as shown in FIG. : 001, softphone identification information 112: PC1) is registered.

  First, it is assumed that the extension telephone terminal 20-1 and the telephone terminal 40-1 are connected and are in a call state (S101).

  Then, the user of the extension telephone terminal 20-1 operates the PC 30-1, searches for information on the telephone terminal 40-1 (S102), and performs an operation of transmitting to the telephone terminal 40-1 using the PC 30-1. Suppose that it went (S103).

  When a signal related to transmission from the PC 30-1 to the telephone terminal 40-1 is given to the IP-PBX 10, the IP-PBX 10 searches for information in the linkage information registration unit 11, and the PC 30-1 (softphone identification information) 112: PC 1), the extension telephone terminal 20-1 (extension telephone terminal identification information 111: 001) is detected as the extension telephone terminal 20 (S104). In step S104, if the corresponding information is not detected in the cooperation information registration unit 11 in the IP-PBX 10, the process ends, and the transfer process described later (the processes in steps S105 to S109 described later) is not performed. .

  In IP-PBX 10, when extension telephone terminal 20-2 is detected as extension telephone terminal 20 linked with PC 30-1, whether extension telephone terminal 20-1 is in a call state with another telephone terminal or not. Is determined. Then, in the IP-PBX 10, when it is determined that the call is not being performed, the process is terminated, and the transfer process described later (the process of steps S106 to S109 described later) is not performed, and it is determined that the call is being performed. Operates from the next step (S105). Here, since the extension telephone terminal 20-1 is in a call state with the telephone terminal 40-1, it is determined that a call is in progress, and the operation starts from the next step.

  Next, a holding tone signal is transmitted from the IP-PBX 10 to the telephone terminal 40-1 (S106), and a calling signal is transmitted to the extension telephone terminal 20-2 (S107). Then, a ringing tone signal is transmitted from the IP-PBX 10 to the extension telephone terminal 20-1 (S108).

  Thereafter, when the extension telephone terminal 20-2 responds, the IP-PBX 10 transfers the call of the extension telephone terminal 20-1 to the extension telephone terminal 20-2, and the telephone terminal 40-1 and the extension telephone terminal 20-2 A call state is established (S109).

(A-3) Effects of Embodiment According to this embodiment, the following effects can be achieved.

  By providing the cooperation information registration unit 11 in the IP-PBX 10 and causing the extension telephone terminal 20 and the PC 30 to cooperate with each other, the user can transfer the call only by an operation from the PC 30 during a call using the extension telephone terminal 20. This makes it possible to simplify the operations required for transfer. In the conventional telephone system (see Patent Document 1), the soft phone and the hard phone can be linked only when making a call. However, in the IP-PBX 10, software can be used even during a call using the hard phone (extension telephone terminal 20). The phone (PC 30) and the hard phone (extension phone terminal 20) can be linked to perform operations related to transfer using the soft phone (PC 30).

  In addition, since the user performs the operation of confirming and transferring the information of the transfer destination on the PC 30 while using the extension telephone terminal 20, the holding time of the other party can be shortened. In addition, since the transfer destination can be specified while checking the transfer destination information on the display of the softphone (PC 30), when specifying the transfer destination with a conventional hard phone (press the hold button and dial the transfer destination number) Compared to (Yes), it is less likely that the destination is wrong. Further, by using the softphone (PC 30) for specifying the transfer destination, more information on the destination (transfer destination) can be used as compared with the conventional registration function such as abbreviated dialing.

  Further, as in step S105 described above, it is checked whether or not the target extension telephone terminal 20 is busy before transferring the call. Thereby, it is possible to prevent the transfer operation from being erroneously started when the target extension telephone terminal 20 is not in a call. Further, when the target extension telephone terminal 20 is not in a call, the softphone (PC 30) can identify the simple call operation and perform processing.

(B) Other Embodiments The present invention is not limited to the above-described embodiments, and may include modified embodiments as exemplified below.

(B-1) In the above embodiment, the extension telephone terminal 20 and the PC 30 are registered in the cooperation information registration unit 11 as a pair of two, but are registered as a group of three or more and linked together. Also good.

  For example, one extension telephone terminal 20 and two PCs 30 are grouped together and registered in the linkage information registration unit 11, and a call is transmitted from any PC 30 to a transfer destination during a call on the extension telephone terminal 20. In such a case, it may be transferred to the transfer destination.

  FIG. 4 is an explanatory diagram showing an example of information registered in the linkage information registration unit 11 when two or more PCs 30 are linked to one extension telephone terminal 20.

  For example, by registering the information as shown in FIG. 4 in the cooperation information registration unit 11, the PC 30 with the host name “PC1” or the host name is in the middle of the telephone call with the extension telephone terminal 20 with the extension number “001” When there is a call from the PC 30 of “PC2” to the transfer destination, the call being connected to the extension telephone terminal 20 with the extension number “001” is transferred to the transfer destination.

(B-2) In the above embodiment, the IP address applied to the PC 30 has been described as a fixed address, but may be a variable address. For example, the IP address applied to the PC 30 is not shown in FIG. 1, but may be a variable IP address given from a DHCP (Dynamic Host Configuration Protocol) server. For example, the IP address range applied to the PC 30 is ff. bb. cc. 00-ff. bb. cc. In the case of ff, “ff.bb.cc. **” (“**” means any value of 00 to ff (hexadecimal) or 0 to 255 (decimal)). It is good also as notation.

  Further, for example, when the IP address is also changed along with the change of the connection destination on the network of the PC 30, the information of the cooperation information registration unit 11 may be registered for each connection destination.

  FIG. 5 is an explanatory diagram illustrating an example of registering information of the cooperation information registration unit 11 for each connection destination of the PC 30.

  For example, the PC 30-1 with the host name “PC1” is “aa.bb.cc.01” when connected to the Tokyo network, and “ff.bb.cc” when connected to the Osaka network. .01 "is applied, the extension number of the extension telephone terminal 20 installed in Tokyo is" 001 ", and the extension number of the extension telephone terminal 20 installed in Osaka is" 003 ". . Then, as shown in the example of FIG. 5, the link information registration unit 11 includes (extension telephone terminal identification information 111: “001”, softphone identification information 112: “PC1, aa.bb.cc.01” , (Extension telephone terminal identification information 111: “003”, softphone identification information 112: “PC1, ff.bb.cc.01”), a total of two pieces of information are registered. When the user of PC30-1 (host name: PC1) is connected to the Tokyo network, the user can be linked to the extension telephone terminal 20 (extension number: 001) in Tokyo, and connected to the Osaka network. Are linked with the extension telephone terminal 20 (extension number: 003) in Osaka, that is, the identifier such as the IP address is different for each connection destination of the PC 30 (soft phone). Even if you, the desired extension telephone terminal 20 and the PC 30 (softphone) and by linking, it is possible to transfer the call as in the above embodiment.

(B-3) In the above embodiment, an example in which a hard phone (extension phone terminal 20) and a soft phone (PC 30) are linked has been described. However, the extension phone terminal 20 may be replaced with a soft phone, The PC 30 may be replaced with a telephone terminal other than a soft phone, and the type of each terminal is not limited. For example, the PC 30 can search the phone book, incoming call history, outgoing call history, and can make a phone call operation on the searched phone number (for example, select a destination and press the call key) (for example, an extension) It may be replaced with a telephone terminal or a mobile phone terminal.

(B-4) In the above-described embodiment, an example in which the IP-PBX 10 is applied as a switching device has been described. However, instead of the IP-PBX, a private branch exchange (PBX) based on conventional circuit switching may be used. In the above-described embodiment, an example in which the IP-PBX 10 is applied as a switching device has been described. However, the present invention may be applied to a switching device included in a communication carrier instead of a private branch switching device (PBX).

(B-5) In the above embodiment, the transfer of the call between the extension telephone terminal 20 and another telephone terminal has been described, but a three-way call may be used instead of the transfer. For example, in the above-described step S109 (see FIG. 3), the IP-PBX 10 transfers a call in progress at the extension telephone terminal 20-1 to the extension telephone terminal 20-2, and the telephone terminal 40-1 and the extension telephone terminal Although 20-2 is in a call state, a three-party call state may be set by three telephone terminals of the extension telephone terminals 20-1, 20-1 and the telephone terminal 40-1. Further, by the same operation as the above-described steps S102 to S108, other telephone terminals may be added and four or more telephone terminals may be brought into a call state.

(B-6) In the above embodiment, the configuration in which the extension telephone terminal 20, the PC 30, and the telephone terminal 40 are connected to the IP-PBX 10 has been described. However, each of them is replaced with another telephone apparatus instead of the telephone terminal. May be. For example, the telephone terminal 40 may be replaced with a telephone device such as an interactive voice response (IVR) that is a system that performs an automatic voice response.

(B-7) In the above embodiment, when the extension telephone terminal 20-1 and the telephone terminal 40-1 are in a call state (see step S101 in FIG. 3 described above), the call is transferred (see FIG. 3 described above). If the extension telephone terminal 20-1 and the telephone terminal 40-1 are connected via the IP-PBX 10 in the above-described step S101, the connection state is determined.
