Administration of the Avaya G350 Media Gateway - Avaya Support

Basic device configurationThe Media Gateway Controller (MGC)The Media Gateway Controller (MGC) controls telephone services on the Avaya G350 MediaGateway. You can use a media server with Avaya Communication Manager software as anMGC. The G350 supports both External Call Controllers (ECC) and Internal Call Controllers(ICC). An ICC is an Avaya S8300 Media Server that you install in the G350 as a media module.An ECC is an external media server that communicates with the G350 over the network.Note:Note: When the G350 uses an ECC, it can use a local S8300 as a backup controller.The S8300 functions in Local Survivable Processor (LSP) mode. If the ECCstops serving the G350, the S8300 takes over the service.Table 2: Media servers supported by the Avaya G350 Media Gateway on page 52 lists themedia servers that can be used with the G350.To register the G350 with an MGC, you need the G350’s serial number. You can find this serialnumber in one of the following ways:●Table 2: Media servers supported by the Avaya G350 Media GatewayMedia server Type UsageAvaya S8300 Media Server Media module ECC, ICC, or LSPAvaya S8500 Media Server External ECCAvaya S8700 Media Server External ECCUse the show system command.● Look for a 12-character string located on a label on the back panel of the G350.Configuring the MGC listThe G350 must be registered with an MGC in order to provide telephone service. Use the setmgc list command to set the G350’s MGC. You can enter the IP addresses of up to fourMGCs with the set mgc list command. The first MGC on the list is the primary MGC. TheAvaya G350 Media Gateway searches for the primary MGC first. If it cannot connect to theprimary MGC, it searches for the other MGCs on the list.Note:Note:To register an S8500 or S8700 media server as the MGC, use the IP address ofthe media server’s Control-LAN card (CLAN) rather than the IP address of themedia server itself.52 Administration of the Avaya G350 Media Gateway
