Case Study: Large US Network Operations Service Provider achieves 50% call‑quality improvement and resolves QoS issues with NETSCOUT nGeniusONE

Execute Maintenance Upgrades with Confidence

A large U.S. service provider faced widespread call-quality problems during network maintenance upgrades when optimized configuration settings were overwritten and subnets were improperly tagged, causing QoS mismatches and poor audio for roughly 50% of customers across multiple markets. The challenge was to detect and prevent these issues proactively so upgrades would not degrade the customer experience.

Using NETSCOUT’s nGeniusONE, the operations team added triggers and standardized reports to detect improperly tagged subnets and QoS policy mismatches before they impacted users. The solution provided clear root-cause visibility, preventative controls to maintain optimized settings, standardized upgrade checks, and early involvement of support — improving call quality and resolving QoS issues across affected markets.
