Cloud VoIP Phone System Upgrade – Chadwicks Solicitors Case Study
Overview
For nearly two decades, our team at Tech IP has supported Chadwicks Solicitors. Back in 2006, we installed their original on-premise telephone system, a setup that served them reliably for 19 years. But with the UK’s announced retirement of ISDN and PSTN in January 2027, Chadwicks Solicitors approached us to future-proof their communications by migrating to a robust cloud-based VoIP phone system. Their return to Tech IP after many years illustrates the value of long-term trust, reliable service, and consistent support.
The Challenge
Chadwick’s traditional ISDN-based telephony was approaching the end of its useful life. Even though it had worked well for many years, the upcoming changes to UK telecom infrastructure made it imperative to act. Among the main issues:
- The imminent ISDN and PSTN shutdown by January 2027 — meaning legacy phone lines would no longer be supported.
- Rising costs — maintaining old hardware, rising line rental fees, and increasing maintenance expenses for ageing telephony infrastructure.
- Lack of flexibility — staff needed to work remotely or in hybrid mode, but the old system tied phone access to fixed office lines.
- Risk of disruption — the firm needed a migration that would not interrupt client communication or daily operations.
Because the 2027 switch-off affects all traditional landlines, ISDN and PSTN services, businesses that rely on them risk losing phone connectivity entirely if they don’t upgrade.
Our Solution
We proposed and rolled out a fully hosted cloud VoIP phone system, a future-proof solution that offered better reliability, flexibility, and long-term savings.
Key Features Deployed
- A cloud-hosted VoIP platform replaced all existing ISDN lines.
- Desktop and mobile softphone apps enabled staff to make and receive calls wherever they worked — in the office, at home, or on the go.
- Advanced call-handling features: call routing, voicemail-to-email, call reporting and analytics, and auto-attendant functionality.
- Business-grade desk phones are provided where required for traditional office use.
- Full migration managed by Tech IP, ensuring a smooth process with zero downtime for Chadwicks’ operations.
By upgrading proactively, Chadwicks Solicitors now enjoys a scalable, modern communications system — well-prepared for the 2027 telecom transition and adaptable for future growth.
The Results
- Future-Proof Communications
- The firm now operates on a resilient, internet-based voice system — eliminating any risk tied to the ISDN switch-off date.
- Their communications infrastructure is fit for future expansion or changes in working patterns.
- Reduced Ongoing Costs
- Monthly line-rental and maintenance expenses vanished.
- Operating costs became more predictable thanks to cloud-based subscription pricing rather than unpredictable hardware upkeep.
- Enhanced Flexibility & Mobility
- Staff can take and make calls from anywhere with an internet connection — supporting hybrid and remote working without loss of contact quality.
- The system adapts easily if the firm adds more users or locations.
- Reinforced Long-Term Partnership
- The fact that Chadwicks returned to Tech IP nearly 20 years after their original install speaks to our consistent reliability, support and customer care.
