Description

  The present invention relates to a button telephone device capable of storing in a voice storage device a voice message from a telephone on the hold side that is held by a hold operation of the extension telephone during an external line call. The present invention relates to a button telephone device that can be stored in an appropriate voice storage device according to the state of the telephone (calling, transferring, or talking on another extension telephone).

  In a multi-function telephone system such as a key telephone device, when a hold operation is performed on an extension telephone during an external line call, a hold sound is sent to the external line, and is received from the telephone receiver or speaker of the telephone line connected to the external line on the hold side. Music on hold is output. Then, when a hold release operation is performed on the extension telephone on the hold side, the hold sound is stopped and the call can be resumed.

  However, in such a multi-function telephone system, there is a problem that the held side is unilaterally waited until the hold is released on the hold side. In addition, if the call is disconnected for the convenience of the held party, only the busy tone is sent to the extension telephone on the holding side, so the holding side only knows that the held party has disconnected. There's a problem.

  Therefore, as a technology that can solve such problems, the voice message from the held side is stored in the voice storage device (mailbox) of the private branch exchange before the disconnecting operation at the held side, and the disconnected operation at the held side There is a call hold recovery method in which when a hold release operation is performed on the hold side after this, a voice message is read from the voice storage device and sent to the extension telephone that has been released from hold (see Patent Document 1).

  However, the above-described call hold recovery method has a problem that the voice message cannot be heard unless the other party who wants to listen to the voice message releases the hold of the extension telephone on the hold side. For this reason, for example, if you search for the other party while on hold but cannot find it, or if you perform extension transfer assuming that the other party is near another extension telephone, you should hear who should hear the voice message. There is no problem.
