Frequently Asked Questions
What is a session border controller and why do enterprises need one?
A session border controller (SBC) is a network security appliance that manages VoIP call sessions between internal networks and external service providers. Enterprises deploy SBCs to enforce security policies, manage bandwidth, ensure interoperability between different vendors' equipment, and protect against fraud and DDoS attacks on voice infrastructure.
How does the Ribbon SBC 5110 support high availability deployments?
The SBC 5110 dual chassis configuration provides high availability through redundant hardware architecture. Both chassis operate in active-active or active-passive mode, automatically failover during equipment failure, and maintain session continuity without service interruption—critical for enterprises requiring 99.99% uptime SLAs.
Can the SBC 5110 handle 10,000 concurrent sessions without upgrades?
Yes, the SBC 5110 with 10,000 session capacity delivers this performance in the standard configuration without requiring additional hardware modules. This makes it ideal for medium-to-large enterprises and regional service providers seeking scalable VoIP infrastructure with predictable capacity planning.
What security features does the Ribbon SBC 5110 provide?
The SBC 5110 includes advanced threat protection, overload controls, SIP protocol validation, media encryption, and comprehensive policy enforcement. These security capabilities protect enterprise voice networks from fraud, DDoS attacks, and unauthorized access while maintaining service quality for legitimate traffic.
