Voicemail is a centralized service used in businesses for sending, storing, and retrieving audio messages. When a user is busy or not available, the caller will listen to a prompt message that contains instructions to leave a voice message to the callee so that they can check it later when available again. The voicemail system also notifies users about new voicemails received to their box and they can access it via their extensions using feature codes or from the user portal.
Voicemail systems make a Phone System more flexible and powerful by allowing information and messages to pass between users even when one of them is not present.
