The toolbox includes pre-launch network and service quality assessment, continuous customer monitoring, and rapid troubleshooting across the enterprise and Service Providers network and service domains. The VoIP Enterprise Customer QoS/SLA monitoring solution uses active test agents that generate simulated traffic to rate performance. As these agents are installed with specific enterprise customers, network and service operations personnel can replicate end-user behavior by taking control over the agents.
