BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call recording / reproducing apparatus, and more particularly to a call recording / reproducing apparatus including a control unit for recording / reproducing a voice signal during a call.

[0002]

2. Description of the Related Art A voice signal talking over a telephone line is compression-encoded, and the compression-encoded voice data is added with relevant information for retrieval related to the voice data and recorded in a recording device, while being reproduced. In this case, a call recording / reproducing apparatus that retrieves and reproduces the voice data using the retrieval related information is known.

Such a call recording / reproducing apparatus is usually a general-purpose computer (general-purpose PC or the like) and a general-purpose computer on the request of shortening device development, facilitating application to a network, or facilitating program development. It is being developed on the basis of a general-purpose OS that runs on.

[0004]

As described above, a call recording / reproducing apparatus developed based on a general-purpose computer and a general-purpose OS uses only an input device such as a keyboard or a mouse when used, and is generally used in a general-purpose computer. It is common to use the connected monitor without connecting it.

By the way, an application program running on the general-purpose computer and the general-purpose OS may fail to start up due to a problem in which the cause cannot be specified. In the case of a normal computer, the user is monitoring the monitor display, and if the startup fails, the user inputs a forced restart instruction of the OS or application program into the computer. This allows the computer to return to normal operation.

On the other hand, the call recording / reproducing apparatus constituted by a general-purpose computer does not have a monitor connected as described above. Therefore, it is difficult for the user to detect the startup failure after the power is turned on. Therefore, the user cannot expect a restart operation. Further, when the OS and the application program are normally started up, the computer may malfunction due to an unexpected input from an input device (keyboard or the like) connected to the computer.

Further, the computer is equipped with the general-purpose OS.
Alternatively, it may be required to perform a setting operation (for example, installation of an OS or application program, state setting performed by directly operating a computer, or operation confirmation operation of an application) before the application program is started or during normal operation. is there.

The present invention has been made in view of these problems, and it is possible to automatically restart the system when an abnormality occurs. Further, it is possible to provide a call recording / reproducing apparatus which can stop the automatic restart and set the state of the computer, and can perform the setting operation when necessary while preventing the occurrence of an abnormal operation.
