  • The Evolution of Session Border Control

    Session Border Controllers have come a long way since they were first conceived in the early 2000s as a simple, security-focused element. As service providers and enterprises began deploying more advanced real-time applications over IP–including Unified Communications, video, instant messaging, and conferencing–the burden on SBCs grew in step.
