A process for a telephone system is disclosed which is associated with customer premises equipment, such as a telephone set or other receiving equipment which has a built-in or attached dual-tone multifrequency (DTMF) receiver-decoder chip connected to an alphanumeric memory chip which is connected to a liquid crystal display (LCD) counter, connected via a RJ11 jack and telephone lines to central office equipment, which allows an incoming caller directory telephone number or any keyed-in telephone number or name initiated by the incoming caller to be transmitted over a called customer busy line (i.e. without call-waiting service), idle line (i.e. with or without call-waiting service) or an in-use line (i.e. with call-waiting service) and received to the called customer premises equipment, which is screened and stored to the equipment's memory for later recall and or redialing. Interoffice and intraoffice application of the disclosed system can be deployed by signaling methods capable of transmitting calling line identification or by dual-tone multifrequency end-to-end signaling. The disclosed system is also designed to interact with existing customer subscribed to telephone services and features, and is a revenue producing service intended for residential and cellular telephone customers.
