Which Avaya product orchestrates routing of SIP sessions across the network?

The Avaya Aura Session Manager (SM) is responsible for orchestrating the routing of SIP (Session Initiation Protocol) sessions across the network. This functionality allows it to serve as a central point for managing SIP signaling, making decisions on how and where to route calls based on the defined policies and the information it gathers about the network.

Session Manager effectively handles SIP integration with various components of the Avaya architecture, ensuring seamless session establishment, modification, and termination while allowing for centralized management of the SIP infrastructure. It plays a crucial role in maintaining interoperability between different systems, enabling efficient call routing, and supporting features such as session replication and security.

The other products mentioned do have important roles within the Avaya ecosystem but focus on different aspects. For instance, the Avaya Aura Media Server handles media processing and transcoding, while the Avaya Aura Communication Manager provides call control functions. The Avaya Aura System Manager exists mainly for system management and administration tasks but does not directly pervade session routing.
