Abstract

A call-details recording device including: a detecting unit detecting a connection or disconnection of a call; a recording unit recording, when the detecting unit detects the call connection, details of the call by storing the voice data of the call-details in a storage device; and a reproduction enabling unit storing, when the detecting unit detects the call disconnection, the voice data recorded by the recording unit in a reproducible format in an accessible area of the storage device, wherein the detecting unit further detects execution of an interrupting operation of interrupting the conversation, and the reproduction enabling unit stores, when the detecting unit detects the interrupting operation, the voice data recorded by the recording unit to a point of time when executing the interrupting operation from a point of time when connecting the call in the reproducible format in the accessible area.

Claims

1. A call-details recording device comprising:

a storage device to store voice data;

a detecting unit that detects a connection or disconnection of a call of a recording target telephone terminal connected to a packet communication network;

a recording unit that records, when the detecting unit detects the call connection, details of the call by acquiring the voice data transmitted and received by the telephone terminal from the network and storing the voice data of the call-details of the telephone terminal in the storage device; and

a reproduction enabling unit that stores, when the detecting unit detects the call disconnection, data including the voice data converted into a reproducible format in the storage device,

wherein the detecting unit further detects execution of an interrupting operation while keeping a call-connected status,

the reproduction enabling unit stores, when the detecting unit detects the interrupting operation, data including the voice data recorded by the recording unit to a point of time when executing the interrupting operation from a point of time when connecting the call after converting into reproducible format in the storage device, and

the reproduction enabling unit updates the data, which is stored in the reproducible format in the storage device, that includes the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call, with the voice data recorded by the recording unit to a point of time when disconnecting the call from the point of time when connecting the call, when the detecting unit detects the call disconnection and the data including the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call is stored in the reproducible format in the storage device by the reproduction enabling unit.

2. The call-details recording device according to claim 1, wherein the detecting unit detects the connection, the disconnection or the interrupting operation of the call of the telephone terminal by acquiring information transmitted and received between the telephone terminal and a device managing the telephone terminal.

3. The call-details recording device according to claim 1, wherein the reproduction enabling unit stores the data including the voice data as a recording file in the storage device, and

wherein the call-details recording device further comprises:

an identifying information acquiring unit that acquires information for identifying the call of which the call-details are recorded; and

a management information accumulating unit that stores the identifying information acquired by the identifying information acquiring unit in the way of being associated with the recording file by way of recording file management information.

4. A call-details recording method by which a call-details recording device including a storage device to store voice data executes:

detecting a connection or disconnection of a call of a recording target telephone terminal connected to a packet communication network;

recording, when the call connection is detected in the detecting, details of the call by acquiring the voice data transmitted and received by the telephone terminal from on the network and storing the voice data of the call-details of the telephone terminal in the storage device; and

reproduction enabling by storing, when the call disconnection is detected in the detecting, data including the voice data recorded in the recording converted into a reproducible format in the storage device,

wherein the detecting involves further detecting execution of an interrupting operation while keeping a call-connected status,

the reproduction enabling involves storing, when detecting the interrupting operation in the detecting, data including the voice data recorded in the recording to a point of time when executing the interrupting operation from a point of time when connecting the call after converting into reproducible format in the storage device, and

the reproduction enabling updates the data, which is stored in the reproducible format in the storage device, that includes the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call, with the voice data recorded by the recording to a point of time when disconnecting the call from the point of time when connecting the call, when the detecting detects the call disconnection and the data including the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call is stored in the reproducible format in the storage device by the reproduction enabling.

5. The call-details recording method according to claim 4, wherein the detecting involves detecting the connection, the disconnection or the interrupting operation of the call of the telephone terminal by acquiring information transmitted and received between the telephone terminal and a device managing the telephone terminal.

6. The call-details recording method according to claim 4, wherein the call-details recording device further, the data including the voice data being stored as a recording file in the storage device in the reproduction enabling, executes:

acquiring information for identifying the call of which the call-details are recorded; and

management information accumulating by storing the identifying information acquired in the acquiring in the way of being associated with the recording file by way of recording file management information.

7. A call-details recording system comprising:

a telephone terminal that is connected to a packet communication network and serves as a recording target;

a storage device to store voice data;

a detecting unit that detects a connection or disconnection of a call of the telephone terminal;

a recording unit that records, when the detecting unit detects the call connection, details of the call by acquiring the voice data transmitted and received by the telephone terminal from on the network and storing the voice data of the call-details of the telephone terminal in the storage device; and

a reproduction enabling unit that stores, when the detecting unit detects the call disconnection, data including the voice data recorded by the recording unit converted into a reproducible format in the storage device,

wherein the detecting unit further detects execution of an interrupting operation while keeping a call-connected status,

the reproduction enabling unit stores, when the detecting unit detects the interrupting operation, data including the voice data recorded by the recording unit to a point of time when executing the interrupting operation from a point of time when connecting the call after converting into reproducible format in the storage device, and

the reproduction enabling unit updates the data, which is stored in the reproducible format in the storage device, that includes the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call, with the voice data recorded by the recording unit to a point of time when disconnecting the call from the point of time when connecting the call, when the detecting unit detects the call disconnection and the data including the voice data recorded to the point of time when executing the interrupting operation from the point of time when connecting the call is stored in the reproducible format in the storage device by the reproduction enabling unit.
