The voice recognition unit 14 detects a keyword (for example, router, Cisco, mobile phone, docomo, e-eu, hodaphone, rabie, bio, auction, soccer, etc.) and pre-loads the VoIP data search system built-in telephone 1 corresponding to the keyword. Registered categories (for example, routers, mobile phones, PCs, auctions, sports, etc.) are assigned, and a keyword list for each category is generated. Next, a category search list in which the assigned category is associated with the call record (for example, 2003/07/03 AM... 0xxx) is generated. Specifically, for example, when the content of a call is “... additional function of mobile phone ...”, mobile phone (mobile phone) becomes a keyword. A mobile phone is assigned as a category corresponding to the mobile phone. A keyword list is generated by the above processing. On the other hand, the category list is generated from the category (mobile phone) corresponding to the keyword (mobile phone) and the call record (2003/07/03 AM... 0xxx). Note that the keyword list and category list generated by the voice recognition unit 14 are stored in the data storage unit 13 together with the text data.

  Next, an operation for searching for voice data stored in the IP phone 1 with a built-in VoIP data search system will be described with reference to FIG. When a search for voice data stored in the VoIP data search system built-in IP phone 1 is requested, the authentication unit 15 confirms the user by a user ID or the like (step S401). When the user ID is authenticated (step S402), it is determined whether or not the user is a registered regular user (step S403). If the user is a legitimate user (step S403 / YES), access to the voice data to which his / her user ID is attached is permitted. The search of voice data is performed by any of history search, category search, or keyword search. Therefore, the user selects a search method (step S404). When performing a history search (step S405 / YES), the user can select / acquire desired voice data from the call history (step S406, step S407). When history search is not performed (step S405 / NO), category search or keyword search is selected. If category search is selected (step S408 / YES), the user first selects a desired category. Next, desired voice data is selected and acquired from the call history included in the category (steps S409 and S407).
