Title: VOIP USING SS7 SIGNALLING AND COOPERATION OF IP NODES WITH SIGNALLING POINTS
Abstract:
A telecommunications system comprises a signalling network (4-7) and a voice over IP (VoIP) network (8a-8d). The signalling network in turn comprises gateway signalling points (6, 7) for converting signalling messages between at least two different signalling protocols. The IP network comprises IP nodes (8a-8d) for routing IP datagrams, with at least certain of the IP nodes (8a-8d) being co-located with respective gateway signalling points (6, 7) and with the co-located signalling points (6, 7) being arranged in use to pass routing information to the respective IP nodes (8a-8d) to enable those nodes to prioritise and route incoming IP datagrams.
