A method in an application server for accessing a messaging server includes receiving, from a browser configured for dynamic control of audio operations, an HTTP request having an audio file that stores received voice signals specifying a messaging operation; identifying the messaging operation in the application server by interpreting the audio file; outputting a function call specifying the messaging operation to the messaging server according to IP protocol; receiving from the messaging server a response to the function call that specifies a stored message; and sending an HTML page to the browser for playback of a second audio file representing the stored message. The step of receiving from the messaging server a response includes receiving the stored message as one of an e-mail message and a voice mail message.
