Abstract

An Intelligent Peripheral (IP) is used in combination with both narrowband type services (e.g., voice mail) and broadband type services (e.g., video transmission) and may provide protocol conversion, message translation, speech recognition, message editing and/or message-to-text conversion. The IP has a gateway switch between the various internal processing modules and the network line or trunk connections. The gateway switch provides selective routing of incoming calls to the appropriate modules, some modules providing narrowband type services and other modules providing broadband processing.
