Mini Sentinel SBC – The World’s Smallest Session Border Controller

The Mini Sentinel SBC is the latest addition to the Mediatrix Sentinel family.
Compact yet powerful, it runs the same Microsoft Teams Certified DGW software as larger Sentinel SBC models, delivering advanced security, universal connectivity, and service continuity in a miniature form factor.
It is designed to meet the needs of operators and system integrators alike, while remaining cost-effective and easy to deploy.

Applications

For Operators

• Provide a network demarcation point with QoS and remote troubleshooting for cost-effective network management and customer service.

• Ensure service continuity in Hosted UC/PBX deployments with phone survivability, failover to geo-redundant core servers, and QoS traffic shaping.

• Secure communications both inside and outside operator and customer networks.

For System Integrators

• Safely connect multiple trunks, branch offices, and remote workers to the enterprise IP-PBX or UC system.

• Perform SIP normalization, translating any vendor-specific implementation into a single, well-defined SIP interface.

• Protect the enterprise IP network by controlling all incoming and outgoing media, signaling, and data flows.

Highlights

• Microsoft Teams Certified for Direct Routing.

• Survivability: automatic failover to secondary trunks or internal routing in case of outages.

• Carrier-grade security: SIP firewall, DDoS prevention, TLS/SRTP encryption.

• Advanced QoS and built-in troubleshooting tools.

• Mass provisioning for fast and cost-effective deployment.
