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 sits at the edge of your IP multimedia infrastructure. It secures, mediates, and controls voice and video communications by performing SIP normalization, policy enforcement, and threat protection. The Ribbon SBC 5400 is essential for enterprises and service providers that need carrier-grade reliability and advanced security for their telecommunications infrastructure.
How does the 15K session licensing tier compare to other options?
The 15,000 concurrent session capacity is ideal for mid-to-large enterprises and regional service providers. The SBC 5400 hardware itself supports up to 75,000 concurrent sessions, so this licensing tier provides flexibility to scale your investment as your organization grows. The dual redundant high availability configuration ensures zero-downtime operations for mission-critical deployments.
Does the SBC 5400 support IPv6 and modern network requirements?
Yes. The Ribbon SBC 5400 includes built-in IPv4–IPv6 interworking, allowing seamless communication between legacy IPv4 networks and next-generation IPv6 infrastructure. This future-proofs your telecommunications platform and ensures compatibility with modern network standards.
What traffic volumes can the SBC 5400 handle?
The SBC 5400 scales from 2 Gbps to 10 Gbps of multimedia traffic, making it suitable for large-scale deployments. Combined with support for up to 75,000 concurrent media sessions on the same hardware, it delivers the performance needed for carrier-grade voice and video services without requiring multiple appliances.
