Automated message processing system having a plurality of expert local facilities responsive to messages routed thereto to perform predetermined actions

An automated message processing system communicates with a digital data processing machine, for example, in replacement of a human operator. The automated message processing system receives messages from a digital data processing machine. The received messages may include immediate-response messages as well as delayed-response messages. Each received message is selectively routed to one of many specialized expert local facilities (ELF) for performance of a designated function, such as generation of an appropriate output message. Each ELF may also generate output messages in response to other stimulus, such as expiration of a timer or receipt of a message from another ELF or an external source. The output message is formatted appropriately and ultimately transmitted to the digital data processing machine.
