Voicemail or voice mail is a telecommunications system that allows users to exchange pre-recorded voice messages; callers record a message that is stored on a server and can be retrieved later by the recipient.
Voicemail is a convenient way to communicate when the recipient is unavailable to answer the phone in person. It is also useful for leaving detailed messages or for sending messages to multiple people at once. Voicemail systems can be used for both personal and business purposes.
