Which technology collaboration is essential for a TSC to secure VoIP traffic?

The security of VoIP traffic is critically dependent on the implementation of Session Border Controllers (SBCs). SBCs serve a key role in managing and safeguarding VoIP communication by acting as intermediaries in voice sessions. They provide several pivotal functions that enhance both the quality and security of VoIP traffic.

One of the primary responsibilities of an SBC is to protect the VoIP network from unauthorized access and attacks. They do this by enforcing security policies, filtering malicious content, and enabling encryption to ensure that voice communications are kept confidential and secure from interception. Furthermore, SBCs help manage signaling and media streams, allowing for voice quality to be optimized while also ensuring that connections can handle any potential threats.

In addition to security, SBCs also facilitate interoperability between different VoIP networks and protocols, which is increasingly important as organizations integrate various communication systems. This aids in seamless communication, regardless of the underlying technology employed by different network participants.

The other options, while related to network infrastructure, do not provide the same level of specialized functionality in terms of securing VoIP traffic. Traditional PSTN networks, for example, do not offer a solution for managing digital voice communications in modern IP-based networks. Routers and firewalls also contribute to securing communications, but they do not
