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. |

1. A method of transferring a first message and a second message, in a Session Initiation Protocol (SIP) based communications network, from a first node to a third node via a plurality of intermediate nodes, wherein the intermediate nodes are a user-to-network proxy entity, a registrar, or a service node, the method comprising:
storing, in a repository associated with the first node, a group identifier associated with a plurality of intermediate nodes; and within a single session or within a single transaction of a session:
deriving, by the first node and based on the group identifier, a network address corresponding to a first intermediate node of the plurality of intermediate nodes;transmitting, by the first node, the first message to the third node via the first intermediate node;synchronizing among the plurality of intermediate nodes data relating to at least one of the first node and the third node;deriving, by the first node and based on the group identifier, a network address corresponding to a second intermediate node of the plurality of intermediate nodes; andtransmitting, by the first node, the second message to the third node via the second intermediate node. |
