According to one embodiment, a voice mail apparatus includes a voice processor which processes voice messages by a arbitrary processing gain, a gain controller which monitors a signal level of an output signal of the voice processor, and controls the processing gain of the voice processor to change the signal level into a specified level, and a processing controller which makes the gain controller to perform gain control of a learning voice by inputting a portion of the voice message into the voice processor as the learning voice when processing of the voice message is requested or based on predetermined conditions.

Voice mail apparatus and control method of voice mail apparatus

The emergency call such as Enhanced 911 call or the like is also originated through an exchange such as PBX (Private Branch Exchange). In this case, the identification information such as the extension number of the extension telephone terminal connected to the PBX should be transmitted to a network corresponding to the emergency call. For the extension telephone terminal, it is necessary to unhook or to capture an arbitrary line by the line key, before inputting the dial data &ldquo;911&rdquo;. Independent of the capture of arbitrary line, the PBX searches a vacant line connected to the network corresponding to the emergency call, captures the vacant line, transmits the identification information such as the extension number, and switches over and connects the extension telephone terminal from the line captured by the terminal to the vacant line. The identification information such as the extension number is notified, not by the DTMF (Dual Tone Multi-frequency) signal expressing data corresponding to the number of dial key, but by using a MF (Multi-frequency) signal expressing more data.

Telephone exchange apparatus

The present invention provides an electronic exchange capable of certainly making forwarding to a telephone at the forwarding destination. When an electronic exchange receives a forwarding acknowledgement signal &ldquo;Facility message&rdquo; from an electronic exchange, if a telephone to be called is idle, the electronic exchange makes the telephone shift to the receiving standby state for the forwarding, turns on an extension button of the telephone and sets the call transmission and the call reception except for the forwarding to be impossible.

Electronic exchange and key telephone system

According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) or a standard telephone (STT) as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals and as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) A control unit (RCTU) determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) or a standard telephone interface unit (RSTU)
