The present invention relates particularly to a method and system for integrating an interactive voice response (IVR) environment into an existing host processing system to provide automated telephone responses to callers to the host system. The integrated IVR environment is highly scaleable with hardware and software open to the host system for in-house modification and/or addition of components and applications to accommodate additional and/or modified host business logic, host applications, and other host requirements. The integrated IVR environment also alleviates the high cost often associated with the purchase, installation, and maintenance of the IVR functionality for a host processing system.
