When an incoming call directed to an extension terminal arrives from an external telephone terminal and the incoming call signal is transferred to a voice mail unit, a voice message detection section of the voice mail unit detects the presence or absence of a voice message from the caller before the extension terminal is notified that recording of the voice message from the caller is started. When the voice message from the caller is detected, a central control section informs the extension terminal that the voice message is detected. A silence detection unit also detects silence continuing for a predetermined time. Invention prevents false voice mail notifications. |
