Voicemail is an automated telephone answering service that allows callers to leave a recorded message for the recipient to retrieve later. Voicemail is typically accessed by dialing a specific number or by pressing a button on a telephone keypad when prompted.
Voicemail has many benefits. It allows callers to leave a message even if the recipient is unavailable to answer the phone. It also allows the recipient to screen their calls and return calls at their convenience. Voicemail can also be used to record important messages or instructions.
