Abstract
A wireless telephone messaging system determines when link performance is inadequate to provide a live connection and re-directs the call to voice mail, preferably informing the caller of estimated delivery time. A mobile handset and base unit determine the rate at which a voice mail message can be delivered. A wireless base unit conveys the accepted voice mail to a mobile handset using a store-and-forward protocol. A voice mail message can preferably be delivered at a rate lower than that at which speech normally has acceptable quality but which is transmissible over the same link having an inadequate performance characteristic for a live connection. A mobile handset stores a conveyed voice mail message for playback by the handset user.
