Abstract
A feature manager that handles the interactions between features in a telephone network is disclosed. A basic call processor transmits a sequence of event messages to the feature manager. The event messages are then transmitted from the feature manager to a subset of feature modules for processing. The feature modules, following receipt of an event message, each formulate a response message that is returned to the feature manager. The response messages contain information that instructs the basic call processor to act. Information contained within the response message is utilized to determine what other feature modules, if any, must be polled. The feature manager formulates a call processor response from the response messages received and returns the call processor response to the basic call processor. The call processor response includes information that instructs the basic call processor to act accordingly.
