<p>In order to perform intermediate operations such as altering or screening messages in a communication network, it would be necessary to provide each signalling gateway with appropriate capabilities. Alternatively these tasks can be performed by a routing element (40) for passing messages between application servers (34,35) and a plurality of signalling gateways (31,32), the routing element (40) being operable to receive a message from one of the application sever (34,35) and a one of the signalling gateways (31,32), the message comprising routing information. The routing element (40) reads the routing infromation, and forwards the message to the other of the application server (34,35) and the one of the signalling gateways (31,32) in accordance with the routing information.</p> |
