A process for converting a point-to-point multimedia call into a bridged multimedia call for accommodating multi-party conferencing. The process utilizes the bearer channel configuration of the standard BRI format to disconnect, one at a time, each bearer channel from the point-to-point call and to reconnect each line to a multipoint control unit (36), whereupon the reconnected lines are individually reformatted in accordance with standard video phone protocol. The process facilitates the continuous and uninterrupted exchange of audio information and data between the point-to-point participants throughout the disconnection and reconfiguration stages of the conversion.

La présente invention concerne un procédé permettant de convertir une communication multimédia point-à-point en une communication multimédia à passerelle pour assurer une conférence à plusieurs interlocuteurs. Le procédé consiste à utiliser la configuration de canal porteur en format débit de base (BRI) standard pour déconnecter, l'un après l'autre, chaque canal porteur de la communication point-à-point et pour reconnecter chaque ligne à un contrôleur multipoint (36), à la suite de quoi, chacune des lignes reconnectées est rétablie dans un format conforme au protocole standard de vidéophonie. Pendant le déroulement des phases de déconnexion et de reconfiguration du processus de conversion, ce procédé permet d'assurer plus facilement un échange continu et ininterrompu des informations audio et des données entre interlocuteurs en point-à-point.
