Catholic School Upgrade to VoIP Without the Cost of New Wiring

St. John the Evangelist Catholic School needed modern IP phones and hands-free paging across their K-8 campus — but the cost of running new Cat 5 or Cat 6 throughout the building threatened to delay the project by a year. Phonewire found a smarter path: reuse the existing Cat 3 wiring and convert it for IP performance, saving the school over $18,000 with zero downtime.

About St. John the Evangelist Catholic School

St. John the Evangelist Catholic School is a K-8 school in Carmichael, California. Like many school campuses, the building’s communications infrastructure had been built incrementally over decades — leaving a mix of aging PBX hardware, analog classroom phones, and wiring that wasn’t designed with modern IP technology in mind.

Challenge: An Outdated PBX System Holding Back School Communication

Administrators at St. John faced a challenge familiar to K-12 schools across the country: an aging PBX phone system and analog classroom phones that couldn’t keep up with today’s communication demands. The school wanted a modern solution — hands-free paging and intercom for immediate campus-wide communication, improved call quality and reliability in every classroom, and a system that would enhance safety and simplify daily coordination for teachers and staff.

The only problem? Upgrading to IP phones typically means running new Cat 5 or Cat 6 cables throughout the building — an expensive, time-consuming process that would mean weeks of disruption to classrooms and hallways.

The Roadblock: Rewiring the Entire Campus

Running new cabling through a busy K-8 school is no small undertaking. The administration weighed the cost, disruption, and physical mess of tearing into walls and ceilings just to install new lines. The expense of new cabling alone was projected to add thousands of dollars to the project budget — potentially delaying the upgrade by another full year while they saved for the additional cost.

The Problem Path
  • Run new Cat 5/Cat 6 throughout the building
  • Tear into walls and ceilings across classrooms
  • Weeks of construction disruption to daily operations
  • Thousands added to project cost for cabling alone
  • Project potentially delayed another year
  • Additional switches and power adapters required
The Phonewire Solution
  • Reuse existing Cat 3 wiring throughout the building
  • No wall or ceiling work required
  • Upgrade completed with zero construction disruption
  • Over $18,000 saved in cabling and hardware costs
  • Project completed on schedule — no delays
  • PoE delivers power and data over the same line

The Solution: A Smarter Way with Phonewire

Instead of replacing every cable, Phonewire proposed a creative alternative: reuse the school’s existing Cat 3 wiring and convert it for IP performance. This approach allowed the school to deploy IP-based phones and paging technology across the entire campus without a single new Ethernet run.

How It Works — Cat 3 to IP Conversion
🔌

Existing Cat 3 Reused

The school’s legacy copper wiring is adapted to carry IP data — no new cable runs required anywhere on campus

Power over Ethernet (PoE)

Power and data delivered over the same line — eliminating the need for additional switches or power adapters at each phone

📞

IP Phones Deploy Normally

Full IP phone and paging functionality — hands-free intercom, improved call quality, modern management — without the rewiring cost

The PoE design also eliminated the need for additional switches or power adapters at each phone location, further reducing both cost and the complexity of the installation.

Results: Seamless Upgrade and Significant Savings

Saved in cabling and hardware expenses

The transition was fast and minimally disruptive — no construction dust, no downtime, and no lost learning days for students or teachers.

Teachers and staff were able to quickly adapt to their new phones and immediately begin using the features the school had been missing:

  • Hands-free paging and intercom for instant campus-wide communication — announcements, emergency alerts, and classroom-to-office calls all handled from the same system
  • Improved call quality and reliability across every classroom and administrative space on campus
  • Simplified system management with future-ready IP technology — adding phones, changing extensions, or managing the system no longer requires a vendor visit

The entire upgrade was completed with minimal impact to daily school operations, transforming outdated infrastructure into a modern communication system built to serve the school for years to come.

Conclusion: Smart Innovation Over Costly Renovation

The most expensive solution isn’t always the right one. By listening closely to the school’s specific constraints — existing wiring, a limited budget, and the absolute requirement of zero disruption to the school year — Phonewire identified an approach that delivered everything St. John needed at a fraction of the projected cost.

“Phonewire turned a costly challenge into a simple, affordable success story — by leveraging the infrastructure the school already had.”
