This section describes how to configure Avaya Aura® Session Manager for Avaya Oceana®.

Avaya Aura® Session Manager is a SIP routing and integration tool that integrates all the SIP entities across the enterprise network within a company. Session Manager provides a core communication service that builds on existing equipment and adds a SIP-based architecture. Session Manager uses direct SIP connections and acts as a system-wide dial plan for call processing applications such as Avaya Aura® Communication Manager.

The SIP network components are known as SIP entities in an enterprise solution. The connections or trunks between Session Manager and the SIP network components are known as entity links. Each SIP entity connects to Session Manager and relies on Session Manager to route calls to the correct destination. This approach reduces the need for manual dial plan and trunking administration for each SIP Entity by consolidating administration in a central location on Avaya Aura® System Manager.
