One embodiment of the present invention provides a system that provides a unified telephony solution. During operation, the system receives a request for a telephony service at a telephony controller. In response to this request, the system accesses a telephony service provided by an application server through a voice extensible markup language (VXML) browser. While performing the telephony service, the system interfaces to a public switched telephone network (PSTN) through a telephony gateway. |
