Abstract

Interconnection of a multimedia terminal (110) of a narrowband, LAN-type network (10) to an exchange (118) and thence to an end-point (119) is orchestrated through an intermediate network (142), as shown in FIG. 5. A route (115) to the exchange (118) is initially established by a call handler (116) in responsive to a called party number of the end-point, before a connection supervisor (120), coupled to the call handler (116), sets up a control channel across the intermediate network (142). The control channel supports the communication of control messages between the multimedia terminal (110) and the end-point (119), which control messages are intercepted and interpreted by the connection supervisor (120). The connection supervisor (120) then establishes media paths through the intermediate network (142) dependent upon types of control message sent across the control channel, which media paths are used to transfer traffic components across the intermediate network.
