Case Study: Comprehensive Products and Services Manufacturer achieves assured SD-WAN conversion and reliable VoIP performance with NETSCOUT virtual visibility

Leading Manufacturer’s SD-WAN Conversion Assured By NETSCOUT Virtual Visibility

A leading manufacturer with a global portfolio and hundreds of remote offices faced a stalled WAN-to-SD‑WAN conversion after pre-deployment VoIP tests over the new SD‑WAN returned faulty results and threatened to halt the project. The company needed virtual visibility into the VMware and SD‑WAN environment to determine whether the problems were real or false positives and to protect business continuity for customer-facing remote employees.

Using NETSCOUT’s nGeniusONE service assurance platform with InfiniStreamNG and vSTREAM virtual appliances, IT teams gained real‑time visibility that quickly identified an Avaya scripting IP issue and VoIP sensitivity to SD‑WAN data flows. The fixes validated the SD‑WAN design, enabled a zero‑touch virtual branch rollout across hundreds of sites, improved VoIP quality, and delivered the expected OpEx and CapEx savings.
