What does the Avaya Aura Session Border Controller (SBC) primarily provide?

The Avaya Aura Session Border Controller (SBC) primarily provides security and interoperability for SIP communications. This is crucial in modern communication systems where Session Initiation Protocol (SIP) is widely used for initiating, maintaining, and terminating real-time sessions that encompass voice, video, and messaging applications.

The SBC acts as a gatekeeper, ensuring that SIP signaling is secure and that communications can occur seamlessly across different networks or between diverse SIP endpoints. It resolves compatibility issues that can arise from different SIP implementations, enabling smooth communication between disparate systems and devices. Additionally, it guards against potential security threats such as denial-of-service attacks and eavesdropping, thereby enforcing policies that protect sensitive communications.

Understanding the primary function of the SBC helps to recognize its role in ensuring a robust and secure communication infrastructure, which is essential for any organization relying on real-time communication technologies.
