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 manages voice calls between your internal network and external SIP trunks or service providers. The Ribbon SBC 1000 protects your network from threats, ensures call quality, and enables seamless communication between legacy systems and modern VoIP infrastructure.
Can the SBC 1000 connect my analog phones to a VoIP system?
Yes. The SBC 1000 includes 4 FXS ports that connect directly to analog phones, fax machines, and legacy PBX systems, while the 4 FXO ports connect to PSTN trunks. This makes it ideal for enterprises transitioning from traditional phone systems to SIP-based networks without replacing all hardware at once.
Is the Ribbon SBC 1000 suitable for branch office deployments?
Absolutely. The SBC 1000 is specifically designed for midsize enterprises and branch offices. Its compact form factor, combined with integrated FXO/FXS capabilities and Medium DSP processing, makes it an excellent choice for distributed voice networks requiring local gateway functionality and security.
What does the Medium DSP do?
The Medium DSP (Digital Signal Processor) handles advanced voice processing tasks including transcoding between different codecs, echo cancellation, and tone detection. This ensures high-quality voice calls and compatibility across diverse legacy and modern voice systems.
