Method for setting up communication paths between access points of a switching system, and switching system implementing said method

Procedure for establishing communication paths between access points of a switching system, the switching system comprises a network packet transmission (54-56) providing a first family of access points, switching means (10, 20, 30, 40) equipped for connection interfaces providing a second family of access points and at least one interface gateway network packet transmission, and processing means call to store configuration data and context data relating to terminals connected to the system through the access points, and to carry out treatment signaling relating to said terminals, wherein establishing a first communication path between access points to link the first and second terminals respectively connected to said points access comprises the following steps when the first path comprises at least one first portion belonging to the packet transmission network (54-56) and a second portion belonging to the switching means (10, 20, 30, 40 ) with an interface gateway (112) between said first and second portions: - associating with said first portion addressing a resource gateway interface in the packet transmission network for connection to the first terminal; - Associating with said second portion addressing a resource gateway interface in the switching means for connection with the second terminal; - Stored in the context data relating to the second terminal, an identification of said addressing resource of the gateway interface in the packet transmission network.
