Abstract

Des modes de réalisation de l'invention concernent un procédé permettant de mettre en œuvre un service d'échange principal et un appareil de passerelle. Ledit procédé consiste en ce qu'un appareil de passerelle reçoit un message de demande d'invitation provenant d'un terminal appelant, que le message de demande d'invitation comprend un identificateur d'échange principal préréglé ; que l'appareil de passerelle envoie des informations d'invite correspondant à l'identificateur d'échange principal au terminal appelant selon l'identificateur d'échange principal, pour inviter le terminal appelant à fournir un identificateur d'extension d'un terminal appelé ; que l'appareil de passerelle transfère, selon l'identificateur d'extension obtenu du terminal appelé, un appel déclenché par le message de demande d'invitation au terminal appelé par le biais d'un serveur SIP, ainsi, le terminal appelant tient conversation avec le terminal appelé. Par le biais des modes de réalisation de l'invention, le problème de la technique actuel, À savoir que la charge du serveur SIP est accrue, étant donné que le service d'échange principal est mis en œuvre par l'adoption du serveur SIP, peut être évité, ce qui réduit la charge du serveur SIP, et assure l'exécution normale du service d'échange principal.
