Case Study
Seamless 3CX migration from a legacy BT phone system
A Yorkshire print business — Print & Creative Services — UK
A Yorkshire print business had been running an ageing BT phone system that was costly, inflexible and increasingly difficult to support. They needed a modern, cloud-based solution that could handle their team's needs without causing disruption to a business that can't afford to be unreachable. iTVerse planned and delivered the full migration to 3CX over a single weekend — on time and with minimal downtime.
Legacy BT system
An ageing on-premise BT phone system — expensive to maintain, difficult to reconfigure, and with limited support available.
No flexibility
Staff couldn't take calls on mobile or work from home on the phone system — a growing problem for a modern, flexible workforce.
Zero tolerance for downtime
As a client-facing business, they couldn't afford phone lines going dark during business hours — the migration had to be planned to the minute.
Rising costs
BT line rental and call costs were significantly higher than modern VoIP alternatives, with no corresponding benefit in features or flexibility.
3CX Phone System
iTVerse deployed 3CX — a modern, cloud-hosted VoIP platform that gives the client full control over their phone system, extensions, call routing and voicemail from a single dashboard.
Weekend deployment
The entire cutover was planned and executed over a weekend, working outside business hours to eliminate the risk of any impact on live operations. Monday morning, the team arrived to a fully working new system.
Number porting
All existing business numbers were ported across cleanly — no change of number, no disruption to clients, no loss of inbound call history.
Mobile & remote calling
Staff can now make and receive calls on their mobile phones using the company number, and work seamlessly from any location — as if they were at their desk.
Near-zero downtime
The weekend cutover meant business operations were completely unaffected — the team arrived Monday to a live, fully configured system.
Numbers retained
All existing business numbers ported successfully — no client communications needed, no disruption to inbound calls.
Flexible working enabled
Staff can now take calls on mobile or from home using the company number — a significant upgrade in day-to-day flexibility.
Reduced call costs
Monthly telephony costs reduced versus the legacy BT system, with significantly better features included.
