DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call recording / reproducing apparatus for recording and reproducing call information transmitted / received via a telephone line.

[0002]

2. Description of the Related Art In a call recording / reproducing apparatus for recording and reproducing call information transmitted / received through a telephone line, an audio signal of the call information transmitted / received through a plurality of telephone lines is encoded, and the encoded audio data is encoded. And DTMF (Dual Tone Multi-Frequ
ency) signal and a DTMF code obtained by decoding the signal are recorded in a recording unit of the call recording / reproducing apparatus.
Japanese Patent Application Laid-Open No. 7-307788 discloses an apparatus for recording telephone conversation contents using a TMF code.

[0003]

In the above call recording / reproducing apparatus, the operator inputs a specific code for classifying the contents of the call using the push button of the telephone after the end of the call. Also, the telephone number of the other party input at the start of the call or the DTMF code input from the other party in the automatic answering system or the like is also recorded as the recording information regarding the voice data. Based on a plurality of pieces of recorded information such as a specific code or a telephone number for classifying these call contents, it is possible to search for voice data and confirm the call contents. However, in a conventional call recording / playback apparatus, even if a search is performed by setting a plurality of search conditions, it is rare that only one call data meeting the search conditions is narrowed down. The extended call data is extracted as a search result. In order to extract the target voice data by searching, it is necessary to select the target voice data by confirming the contents of many call data extracted in accordance with the search condition.

[0004] Extracting target voice data from a large number of call data requires a long time and a large number of operators. For example, a worker interrupts the work of listening to the contents of a call for a break and temporarily turns off the power of the call recording / reproducing device or the search terminal connected to the call recording / reproducing device, or connects to the call recording / reproducing device. If multiple workers are simultaneously listening to the contents of calls on multiple search terminals that have been searched, it will not be possible to determine which call data in the searched voice data has been confirmed for playback, Sometimes the searched call data is double-played and confirmed, or missing. As a result, the efficiency of the operation of confirming the contents of the call of the searched voice data is reduced.

Further, when a worker starts listening to the contents of a call, the conventional call recording / reproducing apparatus cannot immediately know how much work time remains.
It is not possible to plan how many workers must work by the time the work should be completed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a call recording / playback apparatus capable of surely confirming a large number of searched audio data without omission in order to solve the above-mentioned problem.
