Which of the following is NOT a function of a Gateway in Avaya deployments?

The function of a Gateway in Avaya deployments encompasses various tasks that primarily deal with the interconnection between different networks and protocols. One critical aspect of a Gateway's role is converting media and signaling, which allows voice and data traffic to traverse different networks seamlessly. This includes transforming formats and ensuring that calls can be routed between various switches and systems that may not natively support one another.

Facilitating communication between different protocols is another vital function, as Gateways enable the use of disparate signaling protocols and media types to communicate effectively. This includes handling the necessary translations to ensure that voice and video communications can occur across different standards.

Additionally, Gateways provide interfaces for endpoints, allowing them to connect to the Avaya system. This involves managing the connection and communication for both traditional phone lines and modern VoIP signals.

On the other hand, ensuring user authentication is typically not a direct function of a Gateway itself. User authentication is usually handled by other components within the Avaya architecture, such as the Application Server or the Session Manager, which manage user identities and access controls. While a Gateway may indirectly support an authenticated environment through its connectivity capabilities, it does not perform the task of verifying user credentials itself. Understanding this distinction clarifies the primary roles of a Gateway within
