What are two functions of Avaya Aura Session Manager?

Avaya Aura Session Manager functions primarily as a sophisticated SIP routing engine, which allows it to manage and control signaling for SIP-based multimedia sessions. This means that it helps establish, modify, and terminate sessions by routing the SIP messages to the appropriate endpoints based on the configured policies and connectivity relationships within the network.

The capability of acting as a SIP routing engine is essential for integrating various communication services and ensuring seamless operation across different network domains. It also allows for efficient management of session initiation and handling of call control, enabling features like load balancing, user authentication, and service failover.

While other options may describe certain capabilities associated with endpoint registration or specific routing types, they do not encapsulate the core role of the Session Manager as effectively as the ability to act as a sophisticated SIP routing engine. The primary focus on SIP-based operations distinguishes it from functionalities related to H.323 or traditional digital endpoint management, which are not central to the Session Manager's primary objectives.
