This invention makes it possible to deliver the voice portion of a
Multimedia Messaging Service (MMS) message to a recipient without
requiring the recipient wireless stations to be MMS-enabled. A sender
creates an MMS message, and sends it to the wireless station of the
intended recipient. If the recipient wireless station is not MMS-enabled,
the message is conveyed to a message server, where its voice content is
extracted and stored in the interactive voice recognition (IVR) system.
If the intended recipient wireless station supports the Short Message
Service (SMS) protocol, an SMS notification alerting the recipient to the
arrival of a new message is transmitted. In the event that the recipient
wireless station is neither MMS- nor SMS-enabled, the recipient can be
alerted of the receipt of a MMS message by Voicemail, Email, Instant
Message, Page, or another medium able to effect delivery. The
notification includes instructions for accessing the voice portion of the
MMS message from the IVR system.
