The unit is specified as including an SX DUP Memory Card, a Duplication Memory Card that enables hardware-based memory duplication within S-Series deployments to enhance fault tolerance of memory contents. As a 6-slot S8720 chassis, the system functions as a central media server and gateway in enterprise VoIP networks, handling signaling and media traffic for large call volumes and integration with other Avaya media modules. In typical configurations, it sits at the core of a campus network, coordinating with other servers and gateways, and is compatible with Avaya Aura\/Communication Manager software releases designed for S-Series media servers. The SX DUP memory capability complements software-based duplication methods described by Avaya, enabling data redundancy in failover scenarios and contributing to reliability in mission-critical voice environments. This part, identified by A75729-003 and associated with the SX DUP memory card, is positioned for enterprises planning to scale their Aura ecosystem with a robust, modular media server platform suitable for complex call routing, multimedia applications, and high availability requirements.\u003c\/p\u003e\u003c\/div\u003e","brand":"Avaya","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660402655534,"sku":null,"price":283.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f1fb218e-9e56-43c6-8cc3-bfc71d979287.jpg?v=1769537385","url":"https:\/\/plgautomation.com\/products\/avaya-a75729-003-media-server-for-sx-dup-memory-card","provider":"PLG Automation ","version":"1.0","type":"link"}
