The present invention provides a method and apparatus for monitoring page communications in an intercom system having multiple stations connected to a common party line. A station module is connected to and continuously monitors each intercom station. During page communications, the source station from which the page communication originates produces a unique local station signal which is detected by the station module. The station module generates a station identification code in response to a local station signal being detected. The station identification code is transmitted over the existing party line to a master station which recognizes the station identification code. The master station includes a computer interface that provides a standardized signal to an industry standard computer for displaying and recording information regarding page line usage.
