Under Domain Management section you can change Settings on per-domain basis. Settings follow the same convention as ISL Conference Proxy settings, however settings specified on per-domain basis will overrule global settings.
Note: Settings in ISL Conference Proxy are organized hierarchically, meaning that settings appear globally, per-domain and on per-user basis. More specific settings will overrule more general settings, thus per-domain settings will overrule the global settings. However per-domain settings will get overruled by per-user settings.
