Description

  The present invention relates to a key telephone system that accommodates a plurality of extension telephones or an answering voice recording function of a PBX (private branch exchange).

  Home telephones with an absence recording function as a basic function have become widespread, but in recent years, an absence recording function has become common in telephone systems such as a button telephone system and PBX introduced in the company. . In addition, many companies use the caller ID notification function, and the caller ID notification function and the absence recording function are combined to display the other party's phone number and name when playing recorded messages. There has been proposed one that enables visual confirmation of whether recording is from a desired partner without reproducing a business message.

  However, in the method of displaying the other party's phone number or name on the display of the telephone at the time of the reproduction operation, the message is accompanied by the reproduction of the message, so it is necessary to know how many times the message of the message from the desired party is recorded. However, it was necessary to perform a skip operation, and it took time and effort to grasp the presence or absence of a message from a desired partner.

  Thus, a technique is disclosed in which a business message is managed separately in an index part and a business part, and only the index part is played back to improve search efficiency (for example, Patent Document 1).
