Which Avaya component is responsible for the registration of endpoints?

The Avaya Aura Session Manager is the component specifically designed for the registration of endpoints within the Avaya communication architecture. It acts as a central routing and control hub for SIP (Session Initiation Protocol) signaling between endpoints, ensuring proper registration and connectivity of devices such as IP phones, soft clients, and other communication endpoints.

When an endpoint starts up, it sends a registration request to the Session Manager, which maintains a database of registered endpoints. This process is essential for enabling features like call routing, endpoint management, and service availability across the Avaya network.

This capability is critical because it allows for streamlined management of endpoints and ensures that they can communicate effectively with one another and with other Avaya services. By handling the registration process, the Session Manager provides a centralized point of control that simplifies network management and enhances the overall user experience with reliable connectivity.

In contrast, while other components such as the Avaya Aura Communication Manager and the Avaya Aura Media Server perform important functions related to call processing and media handling, they do not handle the registration of endpoints directly. The Avaya Aura System Manager plays a role in the overall management and administration of the Avaya Aura ecosystem but does not manage endpoint registrations specifically.
