Product Description
The AudioCodes Mediant 500 (M500) 1 E1 is a compact enterprise-grade VoIP Media Gateway and Enterprise Session Border Controller (E-SBC) designed for small enterprises, branch offices, SIP trunking deployments, unified communications environments, and IP contact centers. It enables organizations to connect legacy TDM-based PBX systems with modern IP networks, SIP trunks, IP-PBX platforms, and PSTN services. AudioCodes
This configuration provides a single E1/T1 digital interface, with the E1 interface supporting up to 30 voice channels. This makes the M500 particularly useful for organizations migrating from traditional ISDN PRI/E1 infrastructure to SIP-based communications while continuing to use existing telephony equipment. AudioCodes
The Mediant 500 also provides four Gigabit Ethernet interfaces, which can operate individually or in redundant configurations. Its enterprise SBC functionality provides SIP normalization, intelligent call routing, interoperability, media handling, security, and voice-quality management. Security capabilities include protection against denial-of-service attacks, fraud, eavesdropping, and other threats to enterprise voice infrastructure. AudioCodes
The platform supports a wide range of ISDN PRI and CAS protocols, making it suitable for integration with existing PBXs and telecom networks. Management options include a browser-based graphical interface, CLI, SNMP, configuration files, REST API, and AudioCodes management solutions. AudioCodes
This product configuration includes 1-year support, providing support coverage for the supplied AudioCodes solution. The exact services included—such as software upgrades, technical assistance, replacement coverage, and support response level—depend on the specific AudioCodes support/SKU purchased, so these should be stated according to the quotation or support contract.
