A feature that displays a visual interface for voicemail. This interface will list all current voicemail messages on the phone's display, along with options for playing and managing messages. This allows messages to be played and/or deleted quickly, in any order.
By comparison, standard voicemail (not visual) uses an audio-only interface, where users must listen to each message in order, and respond to voice prompts with touch-tone menu commands. (Press 7 to delete, etc.)
