FreeSBC - Session Border Controller
TelcoBridges’ FreeSBC is a carrier-grade session border controller software package, designed for Network- to-network interface (NNI SBC), peering and access functions (access SBC). Scalable from 100 to 60,000 sessions. FreeSBC is a flexible pure-software solution that can be installed seamlessly onto general-purpose servers, popular virtualization platforms and TelcoBridges’ certified servers giving access to an extensive set of call routing, network adaptation and policing functions. Combined with TelcoBridges’ TB Analytics network troubleshooting tools and field-proven SIP stack deployed in more than 100 countries, FreeSBC is the ideal choice for VoIP service providers and enterprises.
