ABSTRACT:
A method for sending out absent messages in an ISDN exchange system to which digital telephones with a plurality of function keys and a LCD screen are connected as extension subscribers. When an extension subscriber of an ISDN exchange system is called up, the ISDN exchange system checks whether the called up extension subscriber's telephone is set in an absent message sending mode, and if any, transmits stored absent message to the caller so as to display on LCD screen of the caller's digital telephone. The ISDN exchange system includes a memory for storing a plurality of absent messages representing different absent reasons depending on the subscriber's various situations. A telephone subscriber can choose in advance a proper one of the plurality of absent messages representing his absent reason before outgoing. Accordingly, when the user's digital telephone is called up, the ISDN exchange system retrieves the chosen absent message from the memory transmitted to be displayed on the LCD screen of the caller's digital telephone.
