Frequently Asked Questions
What is a Session Border Controller and why do I need the SBC 5210?
A Session Border Controller is a critical security and routing device that manages SIP sessions between networks. The Ribbon SBC 5210 protects your communications infrastructure by enforcing policies, normalizing SIP traffic, and preventing unauthorized access while enabling seamless interoperability across multiple vendors and network types.
How does the dual chassis high-availability configuration improve reliability?
The dual chassis design provides automatic failover protection, ensuring that if one chassis experiences an issue, the second immediately takes over without service interruption. This redundancy is essential for mission-critical communications environments where downtime is unacceptable.
Can the SBC 5210 handle IPv6 migration?
Yes. The SBC 5210 includes native IPv4/IPv6 interworking, allowing you to gradually migrate to IPv6 while maintaining compatibility with existing IPv4 infrastructure. This flexibility simplifies network modernization for service providers and enterprises.
What security features protect against DDoS and SIP-based attacks?
The SBC 5210 includes advanced network security capabilities such as DDoS mitigation, threat detection, and comprehensive policy enforcement. These features protect your communications network from volumetric attacks, SIP fraud, and unauthorized access attempts.
