Patent

CA 2692258

A method and system for enforcing the user of a proxy server within an enterprise communication system. The system includes an enterprise voice application server configured to act as a SIP proxy to client devices, and a private branch exchange configured to act as a SIP registrar. The client devices are configured to evaluate incoming SIP requests to determine whether they were received via the enterprise voice application server and, if not, to respond with a SIP 305 Use Proxy message referencing the enterprise voice application server in a Contact field. The 305 Use Proxy message forces the PBX or other intermediate SIP server to reroute the SIP request and any subsequent SIP requests in the dialog through the enterprise voice application server.

L'invention concerne un procédé et un système pour imposer l'utilisation d'un serveur mandataire dans un système de communications d'entreprise. Le système comprend un serveur d'application vocale d'entreprise configuré pour agir en tant que serveur mandataire SIP de dispositifs clients, et un autocommutateur privé (PBX) configuré pour servir de registraire SIP. Les dispositifs clients sont configurés pour évaluer des requêtes SIP entrantes pour déterminer si elles ont été reçues par l'intermédiaire du serveur d'application vocale d'entreprise et, si non, pour répondre par un message SIP 305 "Utiliser serveur mandataire" référençant le serveur d'application vocale d'entreprise dans un champ "Contact". Le message 305 "Utiliser serveur mandataire" oblige le PBX ou un autre serveur SIP intermédiaire à réacheminer la requête SIP et toute requête SIP ultérieure dans le dialogue à travers le serveur d'application de vocale d'entreprise.
