| Service complémentaire d'appel en attente dans les systèmes H.323 |
 |
Cette description de service complémentaire traite des procédures et du protocole de signalisation pour le service complémentaire d'appel en attente (SS-CW) pour les réseaux H.323 (systèmes de communication multimédia en mode paquet). Le service complémentaire d'appel en attente permet à un utilisateur servi de recevoir, pendant qu'il est occupé, une indication l'informant de l'arrivée d'un appel. L'utilisateur peut alors choisir d'accepter, de rejeter ou d'ignorer l'appel en attente. L'utilisateur qui appelle l'abonné occupé est informé de la situation d'appel en attente. La présente Recommandation utilise le "protocole générique fonctionnel pour la prise en charge de services complémentaires dans les réseaux H.323" tel qu'il est défini dans la Recommandation H.450.1. |
