The CallManager system: A platform for intelligent telecommunications services

Abstract

Bellcore's CallManager system is an experimental prototype of a call screening and `follow-me anywhere' service platform that makes use of a personal appointment calendar and a personal phonebook (accessed through the customer's wireline or wireless PDA) to determine the customer's current location and the importance of each caller to the customer. This is an example of a future class of network-provided services that utilize advanced speech processing and customer specific data to greatly enhance the value of the telephone network to the customer. Such services allow important calls to reach the customer while screening out unwanted or unimportant calls. These services can potentially also proactively provide information to a customer `as it happens' wherever the customer may happen to be.
