SBC (Session Border Controller) for Beginners: Zero to Hero

What protects a VoIP network at the edge — security, NAT traversal, topology hiding — general infrastructure knowledge, not a 6X product.

Prerequisites
Recommended: complete VoIP Basics or SIP Trunk Basics first — this assumes basic VoIP/SIP familiarity.
What You'll Learn
  • Understand what an SBC does and why VoIP networks need one
  • Know the core functions: security, NAT traversal, topology hiding
  • Understand the tradeoffs between hardware, software, and cloud SBCs
  • Spot unreliable or fake SBC vendors before you deploy
  • Know how SBC knowledge applies to running your own VoIP infrastructure

Powered by 6X – your VoIP gatekeeper guide! An SBC (Session Border Controller) sits at the edge of a VoIP/SIP network, securing and optimizing sessions. It's real, important infrastructure — but not something 6X sells as a service.

This course teaches the general technology, referencing real vendors as examples. Useful alongside your real, self-serve VoIP Basics or SIP Trunk Basics 6X wholesale account, if you're running your own VoIP infrastructure.
