The invention is directed to techniques for providing an audibly controlled interface for a user of a limited audio-based communication device, for example, a telephony device such as a desktop telephone or a cellular telephone. The communication device has an interface connection with a proxy browser. The user initially accesses the device, such as by picking up the handset, and the proxy browser provides a communication path over a network to a call services application on an application server. The application server provides a response to the initial access signal. The proxy browser receives the response from the application server and plays back an audio output based on the response to the communication device for the user. The user can then respond with a request to the call services application to place an outbound call or to initiate another service provided by the application server via the proxy browser.
