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 routing device that manages SIP-based voice and video communications. It protects your network by normalizing protocols, enforcing policies, managing traffic overload, and enabling secure communication between different network domains. The Ribbon SBC 5400 is essential for enterprises and service providers requiring reliable, secure communications infrastructure.
How many concurrent sessions can the SBC 5400 handle?
The Ribbon SBC 5400 with this configuration supports 10,000 concurrent sessions RTU (Ready-to-Use), providing substantial capacity for mid-to-large enterprise deployments and service provider networks without requiring additional licensing or upgrades.
Does the SBC 5400 support IPv6 migration?
Yes. The SBC 5400 includes built-in IPv4-IPv6 interworking capabilities, enabling seamless communication between legacy IPv4 networks and modern IPv6 infrastructure. This makes it ideal for organizations transitioning to next-generation network protocols.
What SIP normalization features does the SBC 5400 provide?
The SBC 5400 delivers comprehensive SIP normalization including protocol optimization, header manipulation, endpoint compatibility, and standards compliance. These features ensure reliable communication across diverse VoIP endpoints and network environments while maintaining security and performance.
