Avaya Aura® Contact Center (AACC) is Active-Active GR-aware. AACC elements are configured to communicate with primary and secondary System Manager servers. The element communicates with System Manager servers for Authentication and Authorization (A&A) operations such as Single Sign-On (SSO) and Role Based Access Control (RBAC). Usually, the element leverages A&A services from the System Manager server that is closest to the element regardless of whether System Manager is in the primary or the secondary mode. The secondary System Manager can serve A&A requests in the standby and active modes.
