Audiocodes Mediant 500L con 4 interfaces de voz BRI y 1000Bas

Legacy ISDN phone lines and modern IP networks rarely speak the same language, leaving businesses with costly rip-and-replace choices when migrating to VoIP. The AudioCodes Mediant 500L bridges that gap, packing four BRI voice interfaces and dual Gigabit Ethernet ports into a compact session border controller that connects traditional PBX equipment to SIP trunks and cloud UC platforms.

Who is it for

Small branch offices, retail locations, and enterprises with existing BRI lines that need a secure, reliable gateway to SIP-based voice services. It suits IT teams looking for a low-power, fanless device that can sit on a desk or in a rack without adding noise or heat.

Main features

• 4 x BRI S/T ports for direct ISDN connectivity, preserving investment in legacy telephony.
• Up to 50 concurrent SBC sessions and 30 transcoded calls (G.711 to G.729) for flexible call routing.
• Comprehensive voice codec support: G.711, G.729, G.723.1, G.722, Opus, iLBC, AMR-NB/WB.
• Advanced security: SRTP encryption, TLS, SIP firewall, DoS/DDoS protection, and NAT traversal.
• Dual 10/100/1000Base-T Ethernet ports for network redundancy or separation of voice and data.
• Echo cancellation (G.168-2004, 128 ms tail) and fax support (T.38 relay, G.711 pass-through).
• Management via web GUI, CLI, SNMP, and syslog for easy integration into existing monitoring.
