Voicemail (or voice mail, vmail or VMS, sometimes called messagebank) is a centralized
system of managing telephone messages for a large group of people. Voicemail
messages are stored on hard disk drives, media generally used by computers to store
other forms of data. Messages are recorded in digitized natural human voice similar to
how music is stored on a CD. To retrieve messages, a user calls the system from any
phone, logs on using Touch-tones (clearing security), and his messages can be
retrieved immediately. Many users can retrieve or store messages at the same time on
the same voicemail system.
