Abstract: A call flow diagnostic system and/or methods for monitoring, diagnosing and updating a communication network for high bandwidth, real time, feature-rich voice/video communications. An interface component is operatively coupled to the communication network. A monitoring and alert component coupled to the network devices monitors in real time transmission and device status, and the condition, state, routing, transmission, transformation settings, and packet or call routing settings of the network devices. The component collects, debugs and traces information from the network devices. A graphical user interface is coupled to the monitoring and alert component and displays information to an operator about network device status, diagnostics results, alerts, instructions in real time.
