Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller like the Ribbon SBC 5400 acts as a security and intelligence gateway for voice and multimedia communications. It provides network security, SIP normalization, routing control, and policy enforcement—essential for service providers and enterprises managing complex communications environments with multiple endpoints and protocols.
Does the SBC 5400 support IPv6 migration?
Yes. The Ribbon SBC 5400 includes IPv4-IPv6 interworking capabilities, enabling seamless protocol transition and coexistence. This allows organizations to migrate to IPv6 gradually while maintaining compatibility with legacy IPv4 systems.
How does SIP normalization improve communications?
SIP normalization standardizes Session Initiation Protocol traffic across diverse endpoints and networks, eliminating compatibility issues, reducing call failures, and improving overall network reliability. The SBC 5400 automatically corrects protocol variations to ensure consistent performance.
What session capacity does the 500 RT model support?
The SBC-5400-PK4-500 configuration supports 500 real-time sessions, making it suitable for mid-to-large enterprise deployments and service provider environments requiring reliable, high-performance session management with carrier-grade assurance.
