Abstract
The local telephone message announcing device automatically checks a remote telephone voice messaging system for stored messages in a consistent and timely manner, announces the presence of stored messages through an external indicator and automatically connects the user to the stored messages upon entry of a predetermined command by the user. The device checks for the stored messages by detecting a unique tone sent to a user's telephone set or telephone number by the remote telephone voice messaging system to indicate the presence of stored messages. The detection occurs at predetermined time intervals whereby interference with the operation of the local telephone set is minimized. In addition, the device is easily installed by a person without technical expertise and can be adapted to any type of telephone set.
