USING A COMPLEX EVENTS PROCESSOR (CEP) TO DIRECT THE HANDLING OF INDIVIDUAL CALL SESSIONS BY AN INTERACTIVE VOICE RESPONSE (IVR) SYSTEM

Event data messages can be provided by an interactive voice response (IVR) system to a complex events processor (CEP). The event data messages can include a Stream_ID and a series of textual elements. The Stream_ID can uniquely identify a call session between a caller and the IVR system. The series of textual elements can represent speech input provided by the caller. The CEP can create a text string from the series of textual elements of event data messages having the same Stream_ID. The text string can inherit the Stream_ID of the event data messages. The CEP can utilize user-defined business rules to process the text string. When the CEP issues an action message, the Stream_ID of the text string can be appended to the action message sent to the IVR system. The IVR system can modify the call session associated with the Stream_ID of the action message accordingly.
