Abstract
A telephone system includes a data modem that is coupled to a control microprocessor and a Data Access Arrangement (DAA) for detecting a Caller ID. The detected information is used to select a specific action dependent upon the specific Caller ID. Only one relay is needed with no other parts to connect the Caller ID to the data modem. A programmed Intelligent Work Station (IWS) determines whether to respond to the call and the type of response.
