Methods, apparatus, and products are disclosed for dynamically publishing directory information for a plurality of interactive voice response (‘IVR’) systems through an IVR directory service that include: providing a description of a web services publication interface for the IVR directory service; receiving, on behalf of one or more IVR systems, web services publication requests through the publication interface; determining, in response to the web services publication requests, directory information for each IVR system requesting publication; adding the directory information for each IVR system to an IVR system directory; generating a voice mode user interface to reflect the directory information for each IVR system added to the IVR system directory; and interacting, using the voice mode user interface, with a caller to identify a particular IVR system in dependence upon the IVR system directory and query information provided by the caller and to connect the caller with the identified IVR system.
