Maximum number of TGM550s

This capacity is 50 if a combination of 

Avaya G700 Media Gateways, Avaya 

G250 Media Gateways, and G350 

Media Gateways are also controlled 

by the same server. The S8300 must 

reside in a G700 or G350. Therefore, 

the maximum of 50 H.248 gateways 

supported by the S8300 means that 

only 49 of the 50 could be IG550s.

Servers registered as Media 

Gateway Controllers. If an MGC 

becomes unavailable, the IG550 

uses the next MGC on the list.

The built-in SLS module can be 

considered a fifth MGC, although its 

functionality is more limited than that 

of a full scale server.

Maximum total number of 

telephones supported by the 

IG550
