  • Patent number: 6721408
    Abstract: A system and method provide the capability for a visitor to a home or business to leave an audio message for the occupants if they are not present. Outside the home or building, an interface may be provided which is proximate to a doorbell which a visitor may employ when notification by the doorbell has proved unsuccessful. Actuation of a switch on the interface may activate a messaging system which will retrieve a stored phone number and establish a telephonic connection over a telephone network. The telephonic connection may be with a voice messaging system which, in turn, will broadcast via a speaker incorporated into the user interface, a greeting recorded by the occupant. At the end of the greeting, a visitor may then speak into a microphone incorporated into the user interface, and record an audio message. The controller may further be programmed to establish a telephonic connection remotely located between the visitor interface and a telephone.
