Frequently Asked Questions
What is a session border controller and why do enterprises need one?
A session border controller is a network security and management device that sits at the edge of a network to control and manage multimedia sessions. Enterprises use SBCs like the Ribbon 5400 to ensure call quality, enforce security policies, normalize SIP protocols, and manage traffic across complex communication networks.
How does SIP normalization improve network performance?
SIP normalization standardizes Session Initiation Protocol messages across different vendor equipment and network domains. The SBC 5400 normalizes SIP traffic to eliminate compatibility issues, reduce call failures, and ensure reliable multimedia communications between diverse endpoints and carriers.
What is media transcoding and how does the SBC 5400 support it?
Media transcoding converts audio and video streams between different codecs and formats in real-time. The Ribbon SBC 5400 includes built-in transcoding to enable communication between endpoints using incompatible codecs, ensuring seamless multi-modal communication without external processing.
Can the SBC 5400 handle IPv4 to IPv6 migration?
Yes. The SBC 5400 provides IPv4-IPv6 interworking capabilities, allowing organizations to transition to next-generation networks while maintaining compatibility with legacy IPv4 systems. This bridge functionality simplifies network modernization for enterprises and service providers.
