Abstract

L'invention concerne un procédé pour transmettre des informations vocales par l'intermédiaire d'un protocole Internet, lesquelles sont échangées entre au moins deux noeuds, par l'intermédiaire d'un protocole de couche de liaison (PPP) par paquets, les en-têtes de ces paquets étant comprimés, et avec un protocole de transmission orienté liaison (MPLS), à l'aide duquel un tunnel peut être établi de façon unidirectionnelle entre les noeuds mentionnés, qui sont au moins deux. Ce procédé se caractérise en ce que, entre les deux noeuds, dans le sens "vers l'avant" et dans le sens "vers l'arrière", est établi respectivement un tunnel, qu'ensuite les deux tunnels sont combinés pour former une liaison bidirectionnelle, ce qui permet une communication bidirectionnelle, et que les paquets du protocole de couche de liaison (PPP) passent respectivement par un tunnel.
