Description

Overview

Dinstar SBC300 is a compact and high-performance Session Border Controller (SBC) designed for small and medium-sized telecommunication operators. It provides comprehensive SIP-based services including secure network access, robust security, system interworking, flexible session routing and policy management, Quality of Service (QoS), media transcoding, and media processing.

Powered by a distributed multi-core processor with a non-blocking Gigabit switching architecture and an Embedded Linux operating system, SBC300 delivers reliable performance while maintaining low power consumption.

SBC300 supports up to 50 concurrent SIP sessions and 50 concurrent transcoding sessions. It provides secure communications through TLS and SRTP encryption while supporting media transcoding for G.729, G.723, G.711, G.726, iLBC, AMR, and OPUS codecs.

In addition, SBC300 supports WebRTC, allowing desktop and mobile browsers to initiate and receive SIP calls over WebSocket and WebRTC transparently without requiring additional client software.
