The Challenge

In independent schools, IT teams face unique pressure: supporting multiple departments with varying needs, managing legacy systems, and implementing upgrades during tight term-break windows. When an established UK-based independent school found its legacy PBX phone system becoming unreliable, they needed a modern telephony upgrade — one that could be deployed on-premise and on schedule.

They turned to Zen Systems — not just for a proven solution, but for a support team that understood the pressures of working in education.

Why They Chose Zen Systems

The school had been exploring options to replace its ageing PBX. While larger providers could offer generic solutions, they lacked the direct access and responsive support the IT team required.

Zen Systems brought something different: deep 3CX expertise, clear communication, and a team that could work flexibly around school schedules.

“What’s unique, and certainly different from dealing with bigger companies, is that you can access the people you need — whether it’s account management or technical support.”

The Solution

Zen Systems installed an on-premise 3CX phone system, giving the school full control over its telephony infrastructure while modernising every aspect of day-to-day communication.

The implementation included:

• On-site installation of the 3CX system on local servers

• Full replacement of outdated handsets across the estate

• Seamless switchover from the legacy PBX

• Project scheduling during school holidays to avoid disruption

Despite the tight deployment window — common in the education sector — the transition went smoothly, with only a few minor post-installation adjustments.

“We had a few niggling little things — not big issues by any means — but they’re always ready to respond and resolve things quickly.”

What Stood Out: Support That’s Always Available

The real differentiator wasn’t just the technology — it was Zen Systems' responsive and balanced team.

“They’re very personable, but also very technical when you need it. It’s a good team — with a great balance between client-facing and technical sides.”

This level of accessible, consistent support is something many schools struggle to find with larger vendors. With Zen Systems, the school always felt like a valued client — no matter their size.

Built for Education Environments

Zen Systems understands the operational constraints of education:

• Term-time is sacred — projects must fit into short holiday windows

• Systems must be intuitive for all staff

• Support must be fast, direct, and reliable

With an on-premise 3CX solution from Zen, schools benefit from:

• Full control over system infrastructure

• All premium features included as standard

• Lower telecoms costs through efficient call licensing

• Local handsets, softphones, mobile apps, and extension-based routing

• Fast, knowledgeable UK-based support
