The SBC1000 (Session Border Controller) delivers comprehensive security, access, interconnection, routing/policy management, signaling flow control, QoS, and media processing for SIP networks of small and medium-sized telecom operators. It cost-effectively addresses two key challenges in enterprise IP communication systems: secure terminal access and NAT traversal for IP multimedia services. Featuring a distributed multi-core processor architecture, non-blocking gigabit switching fabric, and embedded Linux OS, the SBC1000 achieves high performance with minimal power consumption. It supports up to 500 concurrent sessions, 200-channel voice transcoding, and encrypted SIP over TLS/SRTP sessions. Beyond traditional telecom codecs, its media processing capabilities include wireless and internet codecs such as AMR, OPUS, and iLBC.
