Case Study: Tier One Operator achieves 20–30% troubleshooting improvement for VoLTE call drops with NETSCOUT

Effectively Troubleshoot VoLTE Call Drops

NETSCOUT helped a tier‑one operator that saw rising VoLTE call‑drop ratios after a regional rollout of VoLTE‑enabled devices. The operator faced the risk of costly escalations, long troubleshooting cycles and delayed service launch while trying to isolate causes ranging from RAN coverage gaps and neighbor‑cell interference to phased software mismatches and handover failures in the core.

NETSCOUT’s VoLTE solution delivers end‑to‑end visibility across RAN, Core and IMS—surfacing SIP and failure‑cause messages to pinpoint coverage, capacity or interoperability issues in real time. Using field‑proven best practices, the approach sped troubleshooting by 20–30%, reduced escalations and supported a faster, more reliable VoLTE launch.
