Voice mail prompt is a term used to describe the audio message that is played when someone calls a voicemail system. It is usually a short phrase or sentence that informs the caller of what to do next, such as leaving a message or pressing a certain number. The TONE of the voice mail prompt is an important factor in how the caller perceives the message. A friendly and inviting TONE can make the caller feel welcome, while a harsh or robotic TONE can make them feel unwelcome.
