A microcontroller-based system for intelligent telephony

The design of a microcontroller-based system for intelligent telephony is presented. In addition to providing the ability to play different messages in response to distinct calling parties, the system combines calling number identification with digital recording and playback capabilities to permit audible announcement of the calling party between rings, using the calling party's voice. Implementation issues and plans for future prototypes using newer technologies are discussed. An overview of system functionality, including basic subcomponents and their interaction, is presented. Software and hardware are described, along with suggestions for future work.<
