Description
The AudioCodes Mediant 800C M800C-2ET4S-LA-X8 is a powerful hybrid enterprise session border controller (E-SBC) and media gateway designed for small-to-medium businesses needing secure, resilient, and high-performance voice connectivity.
Engineered to support up to 400 SBC sessions and 124 TDM voice channels, the Mediant 800C seamlessly interconnects IP-PBXs, SIP trunking services, Microsoft Teams Direct Routing environments, and legacy TDM PBX systems. This model includes 2 E1/T1 interfaces, 4 FXS ports, and an integrated 3G/4G modem for resilient branch survivability.
Built for unified communications modernization, the Mediant 800C delivers robust perimeter defense, superior voice quality optimization, and high availability using 1+1 redundancy. Its hybrid architecture allows gradual migration from TDM to full VoIP, optimizing CAPEX and operational efficiency.
Key highlights include OPUS and SILK codec support, comprehensive SIP interoperability, PSTN fallback, and a versatile desktop or 1U rack-mountable form factor — all in a compact platform.
