Case Study: Tier One Operator Company achieves a smooth, on-time VoLTE launch and improved call quality with NETSCOUT

Launch VoLTE Services with Confidence

A tier‑one mobile operator preparing a nationwide VoLTE rollout faced uncertainty about network and engineering readiness for anticipated traffic, challenges in tracking VoLTE quality at scale, and the risk that service issues or negative publicity would slow customer adoption, erode brand equity, or force project delays or rollbacks.

NETSCOUT delivered a VoLTE solution that tracks five critical KPIs with intelligent calculations, regional comparisons, executive reporting and proactive alarms to detect degradations early. The implementation reduced customer‑care calls, enabled swift application of field‑proven best practices, improved service visibility and voice quality, and helped protect the brand while accelerating time‑to‑market (approximately 30%).
