Abstract
A telecommunications system comprises a signalling network and a Voice over IP (VoIP) network. The signalling network in turn comprises gateway signalling points for converting signalling messages between at least two different signalling protocols. The IP network comprises IP nodes for routing IP datagrams, with at least certain of the IP nodes being co-located with respective gateway signalling points , and with the co-located signalling points being arranged in use to pass routing information to the respective IP nodes to enable those nodes to prioritise and route incoming IP datagrams.
