An application server, configured for executing an application defined by XML documents for delivering voice portal services, accesses subscriber attributes from a standardized information database server (such as LDAP). The application server, upon receiving a request from a proxy browser serving a user, accesses the standardized database server to obtain attribute information for responding to the application request. The application server sends a request to a content server for media content based on the HTTP request and the attribute information. The application server generates an HTML page, for execution of the prescribed voice portal service application having XML tags configured for controlling delivery of the media content in an audible format, based on the HTTP request.
