Unlike the G350, the Avaya G250 Media Gateway LAN switching and voice ports are built into the G250’s chassis. However, the G250’s WAN and call controller options are modular, and accommodate the G350’s data WAN media modules, as well as the S8300 media server.
The S8300 media server is a Pentium-based processor that runs a Linux operating system. The S8300 runs Avaya Communication Manager (CM) to provide call control services to the G350. The G350 is compatible with Avaya CM from version 2.1 onwards and backwards compatible with Avaya CM 2.0.
