Restoring reliability in a high-stakes testing environment
A week-long migration that ended years of unpredictable downtime.
When the system you rely on lets you down
An on-premise system nobody could fix
A leading UK supplier of advanced test equipment faced a communications crisis. Their on-premise 3CX system, once overseen by an internal IT technician, began failing repeatedly after that employee left, with no in-house expertise left to troubleshoot it.
No in-house expertise
The one person who understood the system had left.
Multiple days of downtime
Repeated failures hit operations, sales and support.
Continuity at risk
Without reliable phones, the business itself was exposed.
Enter Zen Systems
Fully migrated in a week, not months
The company reached out to Zen Systems on a Thursday. By the following Thursday, they were fully migrated to Zen's high-availability hosted 3CX platform, a cloud-based solution designed to eliminate the very issues they had been battling.
