1 is an overall configuration diagram including a call recording device in the present embodiment. It is explanatory drawing which shows the flow of a process of the call recording apparatus in this Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram including a call recording device according to the present embodiment.

  The call recording device 1 is connected to the communication network 100, relays a call between the calling terminal 2 and the receiving terminal 3, and records the call contents.

  The calling terminal 2 and the receiving terminal 3 are terminals used when a caller and a callee make a call. Each of the transmitting terminal 2 and the receiving terminal 3 may be an IP telephone terminal (including a soft phone), a PSTN (Public Switched Telephone Networks) terminal, or a mobile telephone terminal.

  The communication network 100 is a so-called telephone network, and transmits a call control signal and a call voice. Any of an IP network, a mobile network, and a PSTN network that transmit SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) may be included.

  The call recording device 1 includes a communication unit 11, a recording unit 12, and a combining unit 13. Each unit included in the call recording device 1 may be configured by a computer including an arithmetic processing device, a storage device, and the like, and the processing of each unit may be executed by a program. This program is stored in a storage device included in the call recording device 1, and can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or provided through a network. Moreover, you may comprise each part of the call recording apparatus 1 with a separate apparatus, respectively. Hereinafter, each part will be described.

  The communication unit 11 is connected to the call control process based on the call request from the caller terminal 2 to the callee terminal 3, and to each of the caller terminal 2 and the callee terminal 3. The telephone calls (one-way) are output to the receiving terminal 3 and the calling terminal 2 to bridge the calling terminal 2 and the receiving terminal 3 and establish a single call. Furthermore, each call of the transmitting terminal 2 and the receiving terminal 3 is recorded in the recording unit 12 independently.

  In addition, the communication unit 11 includes storage means for registering information on a destination to be recorded, extracts information on the destination from an incoming call, and refers to the storage means to determine whether or not the call is a recording target. judge. The destination information may include a telephone number and a terminal number such as ISDN.

  The recording unit 12 inputs the calls of the transmitting terminal 2 and the receiving terminal 3 from the communication unit 11 and records them independently.

  The synthesizing unit 13 extracts and synthesizes two corresponding calls recorded in the recording unit 12 and records them as one call.

  Next, a processing flow of the call recording device in the present embodiment will be described.

  FIG. 2 is an explanatory diagram showing a flow of processing of the call recording device according to the present embodiment.

  First, the caller makes a call to the receiving terminal 3 using the calling terminal 2 (step S11).

  The communication unit 11 that has received the call request from the calling terminal 2 determines whether or not the destination telephone number is registered as a record target. If the called party is not registered, it is not a call to be recorded, so the communication unit 11 performs normal call control.

  In the case of a call to be recorded, the communication unit 11 makes an incoming call request to the receiving terminal 3 (step S12).

  When an incoming call acknowledgment is obtained from the incoming terminal 3, the communication unit 11 establishes a call between the incoming terminal 3 and the communication unit 11 (step S13). Subsequently, a call between the calling terminal 2 and the communication unit 11 is also established (step S14).

  And the communication part 11 bridges the call established with each of the transmission terminal 2 and the receiving terminal 3, and establishes it as one call (step S15). Specifically, the call from the call terminal 2 is sent to the call terminal 3, and the call from the call terminal 3 is sent to the call terminal 2.

  In addition, a call between the calling terminal 2 and the receiving terminal 3 is established, a call from the calling terminal 2 is started to be recorded in the recording unit 12 (step S16), and a call from the receiving terminal 3 is started to be recorded in the recording unit 12. (Step S17).

  Since the established call disconnection process is the same as the call disconnection process of a normal telephone service, description thereof is omitted here.

  The combining unit 13 reads out the call record 121 from the calling terminal 2 and the call record 122 from the receiving terminal 3 from the recording unit 12 and combines them to generate a two-way call record 131 (step S18). The storage location of the generated call record 131 may be a storage unit included in the combining unit 13, or may be the recording unit 12 or another storage unit.

  The generation of the bidirectional call record 131 may be performed in parallel with the call processing with the calling terminal 2 and the receiving terminal 3, or may be performed after the call ends. When synthesizing a call in parallel with the call process, a call from the calling terminal 2 and the receiving terminal 3 may be directly input from the communication unit 11.

  In this embodiment, it is determined whether or not to be recorded based on the destination telephone number, but it may be determined whether or not to be recorded using the telephone number of the caller.

  As described above, according to the present embodiment, the communication unit 11 establishes a call with each of the calling terminal 2 and the receiving terminal 3, bridges the established call, and each of the calling terminal 2 and the receiving terminal 3 A terminal used by an end user by recording a call independently in the recording unit 12, and the synthesizing unit 13 reads out the respective call records 121 and 122 from the recording unit 12 and generates one call record 131. Calls can be recorded on the network side regardless of the type. In addition, during a call, each call of the calling terminal 2 and the receiving terminal 3 is recorded independently and separated from the process of combining the two calls, so that the execution timing of the combining process can be arbitrarily set. As a result, since the synthesizing process itself can be performed on demand, the processing capability of the synthesizing unit 13 can be optimized, and the equipment cost of the call recording device 1 can be optimized.
