Description

The Dinstar SBC3000 Pro Session Border Controller (SBC) is a high-performance, carrier-grade security and interoperability appliance engineered for small to medium-sized telecommunication operators and large enterprises. It acts as a critical network element at the border of a VoIP network, providing a robust and highly scalable solution for securing and managing a large volume of SIP-based communication sessions. The SBC3000 Pro is ideal for applications such as SIP trunking, Unified Communications (UC), cloud IP PBX, and contact centers.

The SBC3000 Pro is a dedicated, 1U rack-mountable appliance with a distributed multi-core processor architecture. It is designed for high capacity, supporting up to 5,000 concurrent SIP sessions and 1,500 concurrent transcoding calls. This immense capacity allows it to handle the demanding traffic loads of a large-scale network. The device’s robust functionality is centered around three core pillars:

• Security: The SBC3000 Pro acts as a sophisticated VoIP firewall, protecting the internal network from a wide range of attacks, including SIP hacking, Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks, and toll fraud. It provides advanced NAT traversal, topology hiding, and dynamic blacklists/whitelists to control access and protect internal IP addresses. For enhanced security, it supports TLS/SRTP encryption to secure both signaling and media traffic.
• Interoperability: The SBC3000 Pro is a powerful tool for solving complex interoperability challenges between different SIP vendors and platforms. It performs sophisticated SIP normalization and header manipulation, allowing various SIP endpoints, IP PBXs, and service provider platforms to communicate seamlessly. It also supports transcoding for a wide range of codecs (including G.711, G.729, G.723, iLBC, AMR, and Opus), ensuring that calls can be connected regardless of the codec used by the different endpoints. It also supports WebRTC2SIP to integrate WebRTC clients into the VoIP network.
• Call Control and Routing: Beyond security and interoperability, the SBC3000 Pro provides a flexible and powerful call routing engine. It supports dynamic load balancing, flexible routing based on prefixes, caller/called numbers, time profiles, and other criteria. This intelligent routing ensures calls are directed efficiently and cost-effectively. It also features a Back-to-Back User Agent (B2BUA) for full call control.

For high availability and business continuity, the SBC3000 Pro supports 1+1 Active-Standby redundancy with dual, hot-swappable power supplies. Management is simplified through a user-friendly, web-based graphical user interface (GUI) and can be centrally managed via Dinstar’s Cloud Management System.
