Which Avaya component is responsible for call routing and feature implementation in the Avaya Aura architecture?

Avaya Aura Communication Manager is the core component responsible for call routing and feature implementation within the Avaya Aura architecture. It functions as the central control point for managing voice calls, handling signaling, and directing media streams. This component ensures that calls are routed effectively based on defined policies and configurations, while also providing a variety of telephony features such as call forwarding, conferencing, and voicemail.

The Avaya Aura Communication Manager operates as a robust platform that integrates and manages all aspects of voice communication, making it essential for delivering reliable voice services across the network. It not only routes calls but also facilitates interactions between various components in the Avaya ecosystem, thereby playing a critical role in the overall functionality of communications within enterprises.

While the other components—such as the Avaya Aura Media Server, Avaya Session Manager, and Avaya Application Enablement Server—each have distinct roles, none serve as the primary mechanism for call routing and feature management like the Communication Manager does. The Media Server is focused on processing and mixing media, the Session Manager handles session control and SIP interoperability, and the Application Enablement Server provides APIs for third-party applications but does not directly manage call routing or implement features.
