Abstract

La présente invention concerne un procédé pour établir une liaison de télécopie par un réseau décentralisé (P2P), par ex. un réseau d'homologues, une communication décentralisée réciproque étant possible entre une pluralité d'éléments réseau (P1, P2, P3, GW). Après acceptation d'une liaison de données de télécopie (6) par un premier élément réseau (GW), a lieu tout d'abord la détermination d'au moins un second élément réseau (P1) en tant que point terminal de la liaison de données de télécopie (6), ainsi qu'une interrogation du second élément réseau (P1) en ce qui concerne son statut d'accessibilité. Si l'interrogation au sujet du statut d'accessibilité conduit à l'obtention d'un résultat négatif - par ex. parce que le second élément réseau n'est pas accessible ou est occupé, c.-à-d. entretient couramment une autre liaison de données de télécopie, la liaison de données de télécopie (6) est transférée à un troisième élément réseau (P2).
