The Challenge
Pennyfarthing Homes, a construction business operating across New Milton, Hampshire and into Dorset, was running on an ageing, end-of-life on-premise PBX system supported by legacy ISDN2e lines. With 70 users spread across multiple sites, the platform had become a significant operational liability.
The core pain points centred on three areas:
- Resilience — the legacy PBX offered no redundancy or failover capability, leaving the business exposed to downtime risk.
- Obsolescence — with the system at end of life, ongoing support and maintenance were no longer viable, and ISDN2e lines face nationwide withdrawal.
- Multi-site working — coordinating communications across multiple locations in Hampshire and Dorset was cumbersome and fragmented.
The existing system also lacked several capabilities that modern construction operations demand:
- No remote or mobile working support
- No unified communications platform across sites
- No call recording
- No call analytics or reporting
- No CRM integration
The Solution
T2K Voive & Data migrated Pennyfarthing Homes from their legacy on-premise PBX and ISDN2e infrastructure to 3CX, a modern, software-based VoIP platform. The migration was designed to address every identified gap — delivering resilience, flexibility, and the unified communications capability the business needed.
Key elements of the deployment included:
- Full migration of all 70 users to the 3CX platform.
- Number porting — all existing telephone numbers were successfully transferred, ensuring continuity for clients and contacts across Dorset and Hampshire.
- Multi-site connectivity — all locations unified under a single communications platform, eliminating the fragmentation of the legacy setup.
- Remote and mobile working — staff gained the ability to work from any location using the 3CX mobile and desktop applications.
- Call recording — enabled across the platform for compliance and quality monitoring.
- Call analytics and reporting — providing management with full visibility of call activity and performance.

Why It Mattered
For a construction business operating across multiple sites, communication reliability is not a convenience — it is a business-critical necessity. Running on end-of-life hardware and soon-to-be-withdrawn ISDN2e lines, Pennyfarthing Homes faced a clear and growing risk.
By migrating to 3CX, the business eliminated that risk and moved to a platform built for the way modern teams work: across sites, on the move, and with full management oversight through analytics and reporting. All telephone numbers were retained throughout the migration, ensuring zero disruption to existing client relationships.
