Voice-Mail systems are designed to convey a recorded audio message of a customer directly to the concerned department of the bank. In this system, each service representative has his or her Voice-Mail Postbag in which messages are stored and retrieved upon his return to the desk. Further the interface is used to select, play, and manage messages. It is a delivery method to either play or otherwise deliver the message and provide a notification to inform the concerned authority of a waiting message.
Most systems use phone-networks, either cellular or land-line based, as the conduit for all of these functions. Some systems may use multiple telecommunications methods, permitting recipients and callers to retrieve or leave messages through multiple methods. Simple voice-mail functions as a remote answering machine using a touch-tones as the user interface. More complicated systems may use other input devices such as voice or a computer interface.
