A Session Border Controller (SBC) is a powerful back-to-back user agent device that sits at a point of demarcation for SMB and Enterprise businesses to provide services such as call control, security, interoperability and voice optimization. Purchase the best quality SBCs from our top brands including AudioCodes, EdgeMarc, Patton and more!

Why Session Border Controllers?

  • A high-quality eSBC like Patton’s SN4451 Series will provide a rich set of security features
  • A failover mechanism that delivers survivability for voice and data over a fallback connection to the PSTN.
  • Dual Quality of Service (QoS) mechanisms - Bandwidth Reservation and Downstream QoS
