Abstract
Messages are received at a server and processed to generate data that may include a call back number, envelope information or contact information. Generated data is transmitted to a device that displays a visual notification that includes some of the generated data. The notification may be displayed on the device even if the device is unable to retrieve the message over a data channel. The notification alerts the user that a message is waiting for the user. If the device is subsequently within a data network, the device automatically retrieves the message over a data channel. The device can also establish a voice call with a message server to retrieve the message and can record the message. The device can establish the voice call with the server at a call back number and/or issue a DTMF message request to directly access the message without requiring menu navigation.
