Abstract

A communication system comprises a network (5) connecting two or more end stations (1-4) and operating in accordance with a network protocol to make and break connections between the end stations. A call controller (8) is connected to the network (5), the call controller being responsive to call handling requests to generate instructions which cause the network to carry out the call handling requests while operating in accordance with the network protocol.
