Abstract

La présente invention concerne un serveur de communication (KS) et un procédé pour établir et exploiter une liaison de communication de conférence, au moyen d'un premier et d'un second dispositif de conférence (MCU-S, MCU-W) conçus pour transmettre des flux de données médiatiques d'une conférence à données vocales et pour échanger des données d'une conférence sur le Web. La liaison de communication de conférence est formée d'une combinaison de la conférence à données vocales et de la conférence sur le Web, avec un cercle d'abonnés qui coïncident au moins partiellement. Le serveur de communication (KS) est conçu pour extraire d'un serveur de présence (PS) des informations d'état et des adresses de communication des abonnés (TLN-A, TLN-B, TLN-C). Les informations d'état et les adresses de communication des abonnés (TLN-A, TLN-B, TLN-C) extraites sont utilisées pour établir la liaison de communication de conférence, puis sont au moins partiellement représentées dans les données de conférence sur le Web de la liaison de communication de conférence.
