Abstract

L'invention concerne un procédé de transfert de ticket d'appel, un dispositif de communication et un support de stockage lisible par ordinateur. Le procédé comprend les étapes consistant à : envoyer par une CDF un premier paquet dupliqué suspect à une CGF; si la CDF reçoit un message d'accusé de réception envoyé par la première CGF, déterminer si le message d'accusé de réception est un message d'accusé de réception cible indiquant que la première CGF a reçu le premier paquet dupliqué suspect mais n'a pas reçu un paquet de données cible; et si le message d'accusé de réception est le message d'accusé de réception cible, envoyer par la CDF un premier message de demande à la seconde CGF pour demander à la seconde CGF de sortir un enregistrement détaillé des appels (CDR) de facturation dans le second paquet dupliqué suspect.
