What is the function of the Avaya Session Border Controller within the Avaya Aura architecture?

The Avaya Session Border Controller (SBC) plays a crucial role within the Avaya Aura architecture by providing security and managing SIP (Session Initiation Protocol) traffic. Its primary functions include protecting the network by acting as a barrier between internal resources and external networks, thereby safeguarding against various threats such as denial of service attacks, eavesdropping, and fraud.

Additionally, the SBC facilitates reliable SIP signaling and media handling for voice and video sessions, ensuring that communication is seamless and high quality. It supports tasks such as interoperability between different VoIP systems, managing NAT (Network Address Translation) traversal, and ensuring quality of service (QoS).

Overall, the SBC's capabilities make it an essential component for maintaining secure and efficient communications within the Avaya Aura ecosystem, which is particularly important in enterprise environments where multiple devices and services interact.
