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 management device that sits at the edge of your network to protect, control, and manage SIP-based voice and video communications. The Ribbon SBC 5210 prevents unauthorized access, normalizes SIP traffic, manages call routing, and ensures quality of service—essential for service providers and enterprises protecting their VoIP infrastructure from security threats.
What does high-availability (HA) mean in the SBC-5210-PKG8K-HA configuration?
The HA designation indicates this dual 5210 chassis package is configured for redundancy, meaning two SBC 5210 units work together to eliminate single points of failure. If one chassis experiences an issue, the other seamlessly takes over, ensuring your communications network remains operational 24/7 without service interruption.
How many concurrent sessions can the 8000 session SBC 5210 handle?
The SBC-5210-PKG8K-HA supports up to 8000 concurrent sessions, making it suitable for mid-to-large enterprise deployments and service provider networks. This capacity allows you to manage thousands of simultaneous VoIP calls, video conferences, and multimedia communications while maintaining security and performance.
Does the Ribbon SBC 5210 support IPv6 and modern network requirements?
Yes, the SBC 5210 includes built-in IPv4-IPv6 interworking capabilities, enabling seamless communication between legacy IPv4 networks and modern IPv6 infrastructure. This future-proofs your investment and simplifies network migration without requiring separate gateway solutions.
