Method for performing external call forwarding between internet and telephone network in web-phone system

A method of making the telephone call by retrieval of a call signal using a calling party number in keyphone system by transmitting data of a calling party number to a keyphone terminal to display the received calling party number on a display window of the keyphone terminal when a keyphone main device receive a call through a central office line, and connecting the corresponding line; sensing the reception of a called signal calling the keyphone terminal on the telephone call through a central office line; sensing the input of the key for selecting a waiting call after off-hook ring service is provided for informing the presence of the waiting call to the keyphone terminal on line when the called signal is sensed; transmitting data of the calling party number corresponding to the waiting call to the keyphone terminal to display the calling party number on the display window when the input of the key for selecting the waiting call is sensed; and interrupting the call on the telephone call and connecting the selected waiting call to the keyphone terminal when the input of key requesting telephone call with the displayed waiting call is sensed. Therefore, the telephone call can be rapidly made for an important or impending call received through central office lines.

Method of selectively connecting a received telephone call by utilizing

A caller identification displaying method in a key-phone system includes the steps of generating a ring signal if there is a ring received from an office line, and receiving and registering a caller identification during a pause period of the ring signal, requesting a password if a caller identification key is input, and displaying the registered caller identification information if the input password corresponds to a registered password. Therefore, after receiving and storing a caller identification for an abandoned call for the pause period of a ring signal, when an office line caller gives up a call after a ring is received from an office line, if a subscriber presses a caller identification key for verifying the caller's abandoned number, the caller identification for the abandoned call is displayed. Therefore, it is possible to recognize a telephone number of the caller who abandons his or her call. In addition, the recognized telephone number can be automatically dialed only by pressing the dial key without manually dialing digits of the caller identification.
