Abstract

In the key phone system, when there is no hand cell in the key phone, not only the hand cell call can be made, but also the hook-off state is always maintained so that the speaker phone cannot be talked. To do this, it checks the hook state of the key phone in case of initialization by initial power supply. If it is in the hook-off state, the call mode of the corresponding key phone is set as the speaker phone call mode. The call mode is set to the hand cell / speaker phone call mode, and in the hook-on state, the call mode of the corresponding key phone is set to the hand cell / speaker phone call mode. Also, in response to the key-phone phone being hooked on, it checks the currently set call mode, and when the speaker phone call mode is set, changes the call mode of the corresponding key-phone phone to the hand cell / speaker phone call mode, and the hand cell / speaker phone call mode. If it is set to, the call mode of the corresponding phone phone is changed to the speaker phone call mode in response to the mode modification key input. Therefore, even when there is no hand cell of the key phone, the user can make a call using the speaker phone and change the call mode of the key phone.
