Abstract
Voice and media services are provided over an IP network incorporating a plurality of nodes and in which connection oriented traffic is transported in tunnels via said nodes. SS signalling is provided between nodes. The voice and media components are multiplexed to form a point to point protocol (PPP) session which is switched end to end across the network under the control of the signalling.
