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 routing device that manages SIP sessions between networks. The Ribbon SBC 5110 protects your network from threats, optimizes call quality through media transcoding, enforces policies, and enables seamless interoperability between different telecommunications systems—essential for service providers and large enterprises.
How does the SBC 5110 handle session scaling?
The SBC 5110 scales from 250 to 10,000 concurrent sessions without requiring additional hardware. This flexible architecture allows you to grow your session capacity as demand increases, providing a cost-effective solution that adapts to your business needs without expensive infrastructure upgrades.
What is CAC (Call Admission Control) and how does it benefit my network?
CAC (Call Admission Control) is an intelligent bandwidth management feature that prevents network congestion by controlling which calls are admitted based on available resources. The SBC 5110's CAC power option ensures optimal call quality and network performance by rejecting calls that would exceed bandwidth thresholds, protecting your service quality.
Can the SBC 5110 integrate with existing legacy systems?
Yes. The Ribbon SBC 5110 provides advanced system interworking and media transcoding capabilities, enabling seamless integration with legacy telecommunications infrastructure while supporting modern SIP-based networks. This makes it ideal for enterprises and service providers managing mixed-generation systems.
