Patent

CA 2494453

The present invention provides a system and method for providing fault tolerant IP services that includes establishing a first communication session between an originating telephony device and an application server, through a primary call manager. Failure of the primary call manager may be detected. A second communication session between the application server and a destination telephony device may be established via a back-up call manager. The first communication and the second communication session may be coupled at the application server to establish two-way communication between the originating telephony device and the destination telephony device.

L'invention concerne un système et un procédé permettant d'assurer des services IP à tolérance d'erreur. On établit une première session de communication entre un téléphone d'origine et un serveur d'applications, via un gestionnaire d'appel primaire. Il est possible de détecter une défaillance de ce gestionnaire. On peut établir une seconde session de communication entre le serveur d'applications et un téléphone de destination, via un gestionnaire d'appel de réserve. Les deux sessions peuvent être couplées au niveau du serveur, pour l'établissement d'une communication bilatérale entre les deux téléphones.
