发明名称 SPONTANEOUS CALLER IDENTIFICATION WITH CALL WAITING
摘要 An enhanced telephony call waiting feature is provided wherein identifying information related to a third party wishing to converse with a first party already engaged in a conversation with a second party is spontaneously provided to the first party. The method comprises the steps of the local office sending a call waiting tone having predetermined characteristics to the first party and its apparatus responding thereto by muting its associated handset for a predetermined interval of time. The local office then transmits the identification data relating to the third party and the first party apparatus receives and displays to the first party the identification information related to the third party thereby allowing the first party to either accept or reject the waiting call in the conventional manner but also based on the displayed information.
