1. A method comprising:
receiving, at a network device that is configured to switch incoming and outgoing calls, a list of multiple calls-of-interest to monitor;
detecting, at the network device, a failure of one of the calls-of-interest;
triggering, in response to the detecting, at the network device, diagnostics data analysis of data associated with the failure of the one of the calls-of-interest;
determining, at the network device, based on the diagnostics data analysis, a cause of the failure of the one of the calls-of-interest; and
notifying, by the network device, a management system of the cause of the failure of the one of the calls-of-interest and of recent configuration changes on the network device that are related to the cause of the failure of the one of the calls-of-interest.
