Course Description

Nous vous proposons ce module qui est un lab à 100% pratique où nous vous montrons toutes les phases d'ingénierie réalisées pour la conception d'une solution CENTREX flexible, sécurisée et interconnectée.

Dans ce lab, vous apprendrez : à définir un plan de numérotation, ensuite à le configurer dans le coeur des serveurs, à créer des routes sur les serveurs pour autoriser les appels, à manipuler les headers SIP afin de réecrire/reformatter les numéros de téléphone à votre convenance, à écrire une expression regulière (regex) pour matcher des numéros, à éditer des règles de firewall pour autoriser les flux téléphoniques, à vous familiariser avec les interfaces de différents cloud provider comme google cloud, azure et aws, à comprendre le rôle d'un SBC dans une architecture centralisée, et bien d'autres choses intéressantes.
