Abstract
A first voicemail notification message corresponding to a voicemail message associated with a voicemail system is received at a mobile device. The first voicemail notification message includes a first voicemail message time expiration value which is stored in memory. If an expiration of the first expiration value occurs prior to a predetermined event (e.g. an earlier saving or deleting of the voicemail message), a voicemail message deletion indication is produced at a user interface. If the voicemail message is saved at the voicemail system after retrieval of the voicemail message, a second voicemail notification message is received. The second voicemail notification message includes a second voicemail message time expiration value which is saved in the memory. If an expiration of the second expiration value occurs prior to another predetermined event, the voicemail message deletion indication is produced at the user interface.
