Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller (SBC) is a network security appliance that manages VoIP and multimedia communications traffic. The Ribbon SBC 5400 protects your network by normalizing SIP protocols, enforcing policies, managing overload conditions, and providing threat protection—essential for service providers and enterprises handling high-volume communications.
How does the dual chassis configuration improve reliability?
The dual 5400-2GB chassis in this high availability package provides redundancy and automatic failover. If one chassis experiences issues, the second seamlessly takes over, ensuring zero-downtime operation for mission-critical communications infrastructure.
Can the SBC 5400 handle IPv6 networks?
Yes. The Ribbon SBC 5400 includes IPv4-IPv6 interworking capabilities, allowing you to transition to next-generation networks while maintaining compatibility with legacy IPv4 systems. This flexibility supports modern network architectures and future-proofs your communications infrastructure.
What does the 4,000 sessions RTU license include?
The 4,000 concurrent sessions RTU (Right-to-Use) license enables the SBC 5400 to manage up to 4,000 simultaneous calls or media sessions. This capacity is suitable for large enterprises and service providers with substantial call volumes requiring enterprise-grade session management and security.
