Abstract

L'invention concerne un procédé de mise en œuvre d'un appel par mandataire. Le procédé comporte les étapes suivantes: après qu'un serveur mandataire d'appels a reçu une demande d'appel lancée par un client local via une liaison sous protocole d'initialisation de session (SIP) préétablie entre le serveur mandataire d'appels et le client local, le serveur mandataire d'appels initialise un service d'appel vers une partie appelée de la demande d'appel; et lorsque le serveur mandataire d'appels reçoit un flux de service vocal d'un appel du client local via la liaison SIP, le serveur mandataire d'appels envoie le flux de service vocal à la partie appelée de la demande d'appel. Sont également décrits un autre procédé et un système de mise en œuvre d'un appel par mandataire, ainsi qu'un support de stockage informatique.
