Additional Information

This number also applies if a combination of Avaya G700 Media Gateways, G250 Media Gateways, and G350 Media Gateways are controlled by the same media server.

This number also applies if a combination of Avaya G700 Media Gateways, G250 Media Gateways, and G350 Media Gateways are controlled by the same media server.

This capacity is 50 if a combination of Avaya G700 Media Gateways, G250 Media Gateways, and G350 Media Gateways are controlled by the same media server.

The S8300 must reside in a G700 or G350 media gateway. Therefore, the maximum of 50 H.248 gateways supported by the S8300 means that only 49 of the 50 can be TGM550s.

If an MGC becomes unavailable, the TGM550 uses the next MGC on the list. The built-in SLS module can be considered as a fifth MGC, although its functionality is limited than that of a full-scale media server.
