Cisco AM GW Event log
The
Event log
(
Maintenance > Logs > Event log
) shows key events including incoming calls, connecting
calls and disconnecting calls and error events.

VCS where page 1 is the most recent information.
The level of tracing (to save more or less information in the Event log) can be configured in the
Event capture
filter
page (
Maintenance > Logs > Event capture filter
).
When displaying the Event log, this information or a subset of it can be displayed. In the
Event display filter
page (
Maintenance > Logs > Event capture filter
) filters can be set to remove information from the
displayed log, to enable the reader to focus in on the most relevant information.
