Centralized IP Office branch deployments refers to scenarios where IP Office systems act as local branches within a larger Avaya Aura® network. In these scenarios, Avaya SIP telephones registered with the Avaya Aura® can failback to registering with the IP Office when the connection to the Avaya Aura® is not available for some reason. These are called centralized extensions.

This document does not cover the installation and configuration of SIP centralized extensions.
