A telephone number memory having a called number memory and a received number memory for storing a received number input by an external caller; And a digital voice memory for outputting the absence guide signal of the extension subscriber to the external subscriber and notifying the extension subscriber of the contents stored in the called number memory and the received number memory.

In addition, the caller ID notification method of the key phone system of the present invention for realizing the above-described problem, the first step that the extension subscriber enters the absence signal and the called number to the key phone system, and the external caller to try to talk to the extension subscriber A second step of notifying that the extension subscriber is absent and leaving a received number in the keyphone system; a third step of disconnecting when the external caller inputs a received number into the keyphone system; and an extension through a trunk line in the keyphone system. And a fourth step of disconnecting the access after the subscriber's incoming number is notified and the incoming number of the external caller is notified.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

The caller ID notification device of the key phone system according to the present invention, as shown in Figs. 2 and 3, the key phone system connecting the terminal of the external caller and the terminal of the extension subscriber stores the telephone number input by the extension subscriber and the external subscriber. And a digital voice memory for outputting a voice guidance signal to an external subscriber and informing the extension subscriber of the contents stored in the telephone number memory.

Here, the telephone number memory includes a called number memory for storing a called number input by an extension subscriber and a received number memory for storing a received number input by an external caller for each extension subscriber.

The digital voice memory outputs an extension guide signal of the extension subscriber to the external subscriber by voice and notifies the subscriber by voice of the contents stored in the called number memory and the received number memory.

On the other hand, the caller ID notification method of the key phone system according to the present invention is the first step that the extension subscriber enters the absence signal and the called number in the key phone system, and when the external caller attempts to talk to the extension subscriber in the key phone system A second step of notifying that the user is absent and leaving the received number; a third step of disconnecting when the external caller enters the received number into the keyphone system; and connecting to the called party's called number through the trunk line in the keyphone system. The fourth step of disconnecting the connection after providing the incoming number of the external caller.

Here, the first step may be input through an extension terminal of an extension subscriber connected to the key phone system, or an extension subscriber may be input into the key phone system through an external terminal.

In addition, in the first step, the extension subscriber can input the called number and reconfirm by digital voice of the key phone system.

In the fourth step, if the destination number of the extension subscriber is a text receiver, the reception number is dialed and transmitted as a text message. If the extension number of the extension subscriber is a voice receiver, the reception number is digitally voiced. You can also digitally check the incoming number entered into the system.

Referring to the call number notification device and the method of the key phone system of the present invention configured as described above are as follows.

As shown in FIG. 3, when an external caller wants to talk to an extension subscriber, when the external caller calls the keyphone system using the external terminal, any subscriber of the keyphone system responds first.
