Abstract (en)

[origin: WO0148982A1] Methods and system for connecting exchanges to packet switched networks using virtual trunks are disclosed. In accordance with one aspect of the invention, a first node (b) receives an indication from an originating node (401, a) that a call is to be established on an incoming physical device; the first node (b) determines the destination (404, d) for the call and seizes an outgoing virtual device; and the first node (b) indicates to at least one subsequent node (c) having a closer relationship to the destination (404, d) that a call is to be setup and provides the subsequent node (c) with destination information for the call. Another aspect of the invention repeated communication with subsequent nodes (c) closest to the destination node (404, d) until a destination node (404, d) is notified of the call to be established on a physical device associated with the destination node.
