Abstract:
1. An interactive voice response (IVR) data processing system configured for call interruption handling, the system comprising: an IVR system executing in memory of a computer system configured for coupling to a plurality of telephone endpoints over a public switched telephone network (PSTN); and, a call interruption handling module coupled to the IVR system, the module comprising program code enabled to detect a call interruption between a caller and the IVR system during an established IVR session with the caller, to save state information for the established IVR session in connection with the caller in response to detecting the call interruption, to determine a call back number for the caller, to initiate a call back of the caller from the IVR system using the call back number of the caller and to re-establish an IVR session for the caller by attempting a discrete number of telephone calls to the caller at the call back number, closing the IVR session for the caller if the discrete number of telephone calls fail to result in an re-establishment of the IVR session for the caller, but otherwise re-establishing the IVR session for the caller for a successful one of the discrete number of telephone calls, and to restore the saved state information for the re-established IVR session for the caller.
