Description
The AudioCodes Mediant 500 M500-V-1ET is a compact, high-performance hybrid Enterprise Session Border Controller (E-SBC) and Media Gateway designed for small enterprises and branch offices that require secure, reliable, and flexible VoIP connectivity. Delivering up to 250 concurrent SBC sessions and supporting a single E1/T1 interface with 30 TDM voice channels, this platform enables seamless integration between legacy TDM environments, SIP trunks, IP-PBXs, and cloud communication services.
Engineered with robust perimeter defense, the Mediant 500 protects against DoS/DDoS attacks, eavesdropping, fraud, and unauthorized access. It enhances call quality with advanced voice optimization features and provides local branch survivability, ensuring uninterrupted internal communication during WAN outages with PSTN fallback available.
With its hybrid design, extensive SIP interoperability, encryption support, number manipulation logic, and rich routing capabilities, the M500-V-1ET offers a future-proof solution for enterprises migrating from TDM to full IP communications. Its 1U footprint, high availability options, and versatile network interfaces make it ideal for distributed deployments demanding performance, security, and reliability.
