iSBC Session Border Controller
iSBC（Session Border Controller）Provide rich services such as security, access, interconnection, routing/policy management, signaling flow control, QoS and media processing for the SIP networks of large, medium and small enterprises.
Product Overview
With the continuous development of communication network convergence, application scenarios such as IP-based voice, video, conferences, and converged communications in modern enterprises have become essential for daily work.
The iSBC provides rich services such as security, access, interconnection, routing/policy management, signaling flow control, QoS, and media processing for the SIP networks of large, medium, and small enterprises. The device adopts a multi-core processor, non-blocking Gigabit switching network, 10 Gigabit switching network, and Linux operating system. While achieving high performance, it also supports dual hot-swappable power supplies and has carrier-grade high reliability. The device supports 5000 concurrent sessions and 1500 channels of voice media transcoding processing, and also supports SIP over TLS and SRTP encrypted sessions, which is safe and reliable.
