Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller (SBC) is a critical security and interoperability device that sits at your network edge. It protects your VoIP infrastructure from threats, manages protocol translation between different systems, handles NAT traversal, and ensures call quality. The Ribbon SBC 1000 is essential for enterprises integrating legacy telephony with modern VoIP.
What's the difference between FXO and FXS ports?
FXO ports connect to external phone lines (PSTN), while FXS ports connect to analog phones and devices. The SBC 1000's 4 FXO and 4 FXS configuration allows you to bridge traditional phone systems with VoIP networks, supporting both incoming lines and analog endpoints.
Is the Ribbon SBC 1000 suitable for branch office deployments?
Yes. The SBC 1000 is specifically designed for midsize enterprises and branch offices. Its compact form factor, combined with 4 FXO/FXS ports and medium DSP, makes it ideal for distributed network locations that need enterprise security and interoperability without excessive complexity.
What does the medium DSP do?
The medium DSP (Digital Signal Processor) handles advanced audio processing, including codec conversion, echo cancellation, and voice quality optimization. This ensures clear, reliable calls regardless of the codecs or protocols used by connected systems.
