Voicemail is a electronic message system that records and stores voice messages from phone calls when the person you are calling is not able to answer, or when they are not available to pick up the phone. It is like leaving a voice message on someone's phone, which they can listen to later when they have the time. Voicemail is mostly used in offices or on mobile phones, and it helps to communicate important information or updates to someone who cannot take your call.
