Every Building Had Its Own Phone System

A school spread across multiple buildings had a phone setup that existed only because it always had. Every building had its own copper circuits and its own PBX, and none of them was connected to the others.

Everyone in the office lived with the result. A call arriving at one building for someone in another couldn't be transferred, so staff took a message or read out a different number for the caller to redial, for colleagues a few miles away. Staff whose jobs moved them between buildings could only be reached at whichever desk they were near, which meant missed calls all day.

• A separate phone system in every building, each with its own copper circuits and its own bill
• No transfers or forwarding between buildings
• Handsets from the quasi-digital era, aging past the point of replacement parts
• Staff who move between buildings, unreachable in transit and often after they arrived
• Several sets of line charges and PBX maintenance, adding up to a bill sized for the setup's complexity

Nobody chose this. Each building's system was bought separately, years apart, when that was how phones were bought, and the school kept paying every month because nobody had revisited the question.

Tech Dynamix replaced all of it with one cloud VoIP system serving every building, set up as a hosted phone system.

The buildings now work as one organization on the phone. Extensions dial each other regardless of building, and calls transfer between buildings the way staff always expected them to. The aging handsets were replaced with current VoIP phones, and staff who move between buildings got the mobile app, so their extension travels with them and rings wherever they are.

The part that took planning was timing. Porting phone numbers is the step in any phone migration where service can be interrupted, and a school has something most businesses don't: a summer break. We scheduled the cutover into the break and ported the numbers while nobody was calling, so when staff returned, the new system was simply how the phones worked.

The same approach works outside schools. We schedule a migration around the client's calendar, and every organization has quieter weeks if somebody asks.

The school has been on the system for several years, and the monthly bill is roughly half what the old setup cost.

• One phone system across every building, in place of one per building
• Transfers and forwarding between buildings, which the old setup couldn't do at any price
• Roughly half off the monthly bill, with the per-building copper circuits and PBX maintenance gone
• Current VoIP handsets in place of aging quasi-digital sets
• Staff who move between buildings reachable anywhere through the mobile app
• A cutover over summer break that nobody noticed

The savings came from removing duplication. The school had been paying for several small phone systems' worth of infrastructure to do less than one system could, and removing it produced both the savings and the better service.

Old phone setups rarely announce themselves as the problem. They cost double and do half until somebody adds it up, which is where we start with schools and businesses looking at VoIP and business connectivity.
