Abstract
A method for returning a voice mail message for a subscriber of a voice mail service. The method includes the steps of accessing the voice mail service on a second calling line on the public switched telephone network, playing a first voice mail message for the subscriber, the first voice mail message having been received on a first calling line from a source and the first calling line number having been recorded, receiving a call back indication from the subscriber, automatically generating a call to the source, connecting the subscriber to the first calling line, monitoring the call to determine when the call is terminated, and returning the subscriber to the voice mail service.
