ABSTRACT:
An improved call waiting feature implementation for use with conventional analog station sets. When a called station is busy, a call waiting signal is transmitted to the called station. If the called station flashes, a communication path betwaeen the previous caller and the called station is disconnected and the calling party name is spoken, using text-to-speech, to the called station. If the called party chooses to take the new call after learning the calling party name, the called station transmits a DTMF digit or allows the expiration of a predetermined time period without signaling. In response a communication path is completed between the second caller and the called station. If the called party chooses to instead return to the previous call, the called staion flashes. In response a communication path is completed between the previous caller and the called station.
