Page 50 of 258 Ba ndwidth Management 553-3001-207 Standard 2.00 January 2006 Introduction CS 1000 supports Bandwidth Management on a network-wide basis so that voice quality can be managed between multiple Call Servers.
Bandwidth Man agement Page 51 of 258 Main Office C onfiguration for Su rvivable Remote Gateway 50 Configuration Guide By default, the G.7 11 codec must be su pported at bo th ends of a call. Codec configuration is performed for each node and is independent of the signaling gateway that is used on the node.
