Method of transferring a message in a Session Initiation Protocol based communications network, from a first node to a third node via a second node. The method comprises the steps of: storing, in a repository associated with the first node, a group identifier associated with a plurality of second nodes; deriving, by the first node, on the basis of the group identifier a network address corresponding to one second node of the plurality of second nodes; and transmitting the message to the third node via the second node derived by the first node. |
