What is the common name of the key IP address that applications and H.323 endpoints will communicate directly with in the Avaya Aura Communication Manager Duplex Cluster?

The term "Alias IP address" is commonly used in the context of Avaya Aura Communication Manager Duplex Clusters to refer to the key IP address that applications and H.323 endpoints communicate with directly. This alias serves as a single point of contact for communication across the cluster, allowing endpoints to connect without needing to distinguish between the multiple servers that may exist in a duplex setup.

This alias simplifies the configuration and management of H.323 endpoints, as they can reference a single IP address that actually encompasses the necessary routing to the correct applications or servers. Essentially, it abstracts the complexity associated with having multiple nodes in a duplex cluster and ensures consistent connectivity.

In contrast, the other terms mentioned do not accurately describe this concept within the context of Avaya’s architecture. While the aspects of the cluster and communication methods may be relevant, they do not specifically designate the key IP address used for direct communication as effectively as "Alias IP address" does.
