Abstract

La présente invention concerne un procédé et un système permettant de déclencher la fin d'une session de voix sur le protocole Internet (VoIP). Lorsque, au cours d'une session VoIP, un terminal remplit les conditions de déclenchement, par exemple en cas d'équilibre insuffisant ou d'arriéré, le côté réseau indique au serveur VoIP du terminal de mettre fin à la session VoIP entre les terminaux, de manière à mettre fin à temps à la session VoIP entre les terminaux, ce qui évite le gaspillage des ressources et les erreurs de facturation du serveur VoIP envers l'utilisateur du terminal. De plus, en cas de téléassistance et d'autres services pour le terminal au cours de la session VoIP, le côté réseau indique au serveur VoIP du terminal de mettre fin à la session VoIP entre les terminaux, de manière là encore à mettre fin à temps à la session VoIP entre les terminaux et à éviter le gaspillage des ressources et les erreurs de facturation du serveur VoIP envers l'utilisateur du terminal.
