ll services in NSC report logging at different levels. You can consult the application logs at “Reports -> System -> NSC Logs”. The most important service logs are the logs for the “NetBorder Session Controller” service, which have their own tab (See below). There you can find relevant information, including SIP messages received and sent from the system.
When debugging problems it may be necessary to enable debugging logs for NSC.
You can find the core logging level available at “Configuration -> Core”.
