ABSTRACT:
A method and apparatus for monitoring stations from a monitoring terminal wherein at least one of the monitored stations is served by a different switch than that serving the monitoring station. Changes of status are reported by a monitored station to the switch serving the monitored station and, if that switch is not the switch serving the monitoring station, the switch serving the monitored station transmits a common channel signaling (CCS) signaling system 7 (SS7) message to the switch serving the monitoring terminal. Advantageously, this permits an attendant at the monitoring terminal to serve users not connected to the switch serving the monitoring terminal.
