Abstract
An audio alerting announcement signals a subscriber during an ongoing call with a distinctive tone to indicate the identity of another party who is trying to call the subscriber. A telephony call-waiting subscriber customizes Call Waiting indicators in order to give immediate recognition of caller or caller classification via audio signaling. The caller or caller classification is based on the calling party's Line Number ID. This capability is not restricted to the public switched telephone network (PSTN) environment, but will function equally well in a voice-over-IP telephony network as well, on a network such as the World Wide Web, or will function in a hybrid system containing elements of both PSTN and voice-over-IP networks.
