ABSTRACT:
A telephone apparatus for screening calls on the basis of messages containing message data, the messages being transmitted by a central office before a first ring burst is transmitted by the central office. The apparatus includes a message receiver, a decoder, a ringer and a ringer controller. The message receiver is in communication with the central office line and is operable to receive a message while the telephone is on-hook. The decoder decodes the message to extract the message data from the message. The ringer is operable to sound an audible alarm when a telephone call is received and the ringer controller prevents the ringer from sounding in response to the first ring burst, when the message data satisfies a pre-defined condition.
