Configuration Freeze and Configuration Change
Event
In a typical deployment, the Media Gateway is configured by authorized personnel as
part of initial site setup and only routine maintenance tasks such as locking or
unlocking specific trunks or performing VoP board switchover are performed later on.
For such environments, it may be desirable to “freeze” the Media Gateway
configuration to prevent its change by mistake.
When Media Gateway configuration is “frozen”, any attempt to alter it (e.g. change the
value of a configuration parameter) will fail with a corresponding error message.
Regular maintenance tasks (e.g. lock and unlock) are supported in a “frozen” state.
A “Frozen” Media Gateway includes the following indication at the top of the status
screen in the EMS:
To freeze Media Gateway configuration:

and then i

a
tion pane, click

; the Security Settings screen is displayed.
3.

.
An alternative approach to freezing Media Gateway configuration is to use a
Configuration Change Event. When the latter is enabled, the Media Gateway issues
an event, visible in the EMS Alarms Browser upon each configuration change. This
event contains a full description of the change.
To enable Configuration Change Event:
1.
Click
to access the Media Gateway status screen.
2.
In the Navigation pane, select
Security
and then in the configuration pane, click
Security Settings
;
the Security Settings screen is displayed.
