Frequently Asked Questions
What is a session border controller and why do enterprises need one?
A session border controller like the Ribbon SBC 5400 sits at the edge of your network to manage, secure, and optimize voice and video sessions. It provides SIP normalization, media transcoding, and policy enforcement—essential for enterprises managing complex VoIP environments, connecting multiple carriers, or ensuring regulatory compliance across distributed communications infrastructure.
How does the SBC 5400 handle IPv4-IPv6 interworking?
The SBC 5400 includes built-in IPv4-IPv6 interworking capabilities, allowing seamless communication between legacy IPv4 networks and modern IPv6 deployments. This eliminates compatibility issues during network transitions and ensures your communications infrastructure remains future-ready without requiring separate gateway hardware.
What does 250 sessions RTU mean for my organization?
The 250 concurrent sessions RTU (Ready-to-Use) license means your SBC 5400 can simultaneously handle up to 250 active voice or video calls. For enterprises averaging 50-100 concurrent sessions, this provides substantial headroom for peak traffic periods while maintaining performance and reliability.
Can the SBC 5400 transcode media between different codecs?
Yes. The SBC 5400 includes built-in media transcoding, allowing it to convert between different audio and video codecs in real-time. This flexibility enables your organization to support legacy endpoints alongside modern devices without compromising call quality or requiring endpoint upgrades.
