Some example embodiments include a method of dynamically publishing directory information for a plurality of interactive voice response (‘IVR’) systems. The method includes receiving, by the IVR directory service on behalf of one of the IVR systems, a web services update request. The method includes determining, by the IVR directory service in response to the web services update request, updated directory information for the IVR system. The method includes updating the IVR system directory with the updated directory information for the IVR system. The method includes generating an updated voice mode user interface to reflect the updated IVR system directory with the updated directory information for the IVR system. The generating includes creating one more voice dialogs in accordance with the directory information, the one or more voice dialogs specifying a call flow defining the interaction between a caller and the IVR directory service.
