What is a key feature of Avaya Gateways in communications?

A key feature of Avaya Gateways is protocol conversion. This functionality is crucial because it enables different communication systems and devices to interoperate, regardless of the protocols they originally support. In an environment where multiple types of communication devices are used, such as VoIP phones, traditional PSTN lines, and various IP-based systems, the ability to convert between these protocols allows seamless communication and data exchange. By supporting diverse protocols, Avaya Gateways ensure that businesses can integrate legacy systems with modern services, enhancing overall operational efficiency.

The other options do hold importance in different contexts, but they do not specifically highlight the principal role of Avaya Gateways. Real-time video processing is typically associated with specific video systems rather than gateways. Data compression, while beneficial for bandwidth management, is more closely related to transmission efficiency rather than the core function of the gateways themselves. User management usually pertains to system administration aspects, not the primary communication handling capabilities of the gateway.
