Abstract
A voice mail system that allows for the delivery of voice messages by chunks, thereby optimizing the delivery of the information. When a subscriber attempts to listen to his or her voice mail message, the header information for the first voice mail message is down loaded and played back to the subscriber. While the subscriber listens to the header information, the next two blocks of data of the voice message are downloaded. Upon the completion of the playback of the header information, the first two blocks of the voice mail message are available for playback and the first block is immediately available for playback. As the subscriber listens to the voice mail message subsequent blocks of the first voice mail message, and optionally header information and blocks of subsequent voice mail messages are simultaneously down loaded. Thus, the subscriber is able to seamlessly listen to the voice mail messages without a delay in the retrieval of the voice mail messages regardless of the order the subscriber listens to the messages.
