Unifying Communications Across Three Offices for a Growing Law Firm

With the UK's ISDN switch-off looming, this three-office law firm needed unified comms, cloud email and watertight GDPR compliance - all without disrupting client work.

The Challenge

Harcourt & Bruce operate from three offices across Essex, each running a different, ageing phone system tied to lines the UK's ISDN switch-off would soon retire. Email and file storage were split across an old on-premise server, and with client data at the centre of everything the firm does, the partners were increasingly worried about their GDPR position.

Fee-earners needed a system that worked identically wherever they were sitting, without weeks of disruption to client-facing work.

The Solution

39D designed a phased migration that unified all three offices onto a single VoIP phone system, ported every existing number and rolled out softphone apps so fee-earners could work from any location. Alongside this, we migrated the firm's email and document storage onto a fully hosted Microsoft 365 environment, and ran a full GDPR Consultancy engagement to review data handling, retention and staff training.

  • Single VoIP platform deployed across all three offices with number porting
  • Mobile and desktop softphone apps rolled out for remote and court-day working
  • Full migration to hosted Microsoft 365 for email, files and collaboration
  • GDPR audit, updated policies and staff training delivered firm-wide

The Results

The firm now runs as one connected practice rather than three separate offices, with calls, email and files behaving identically wherever a fee-earner is working. Monthly telecoms costs fell by 32%, and the firm passed its most recent GDPR compliance review without a single major finding.

Partners now receive plain-English quarterly reports covering both IT performance and data-protection posture.

Moving to VoIP and Microsoft 365 felt daunting, but 39D planned every step. Our fee-earners didn't lose a single billable hour to the migration.
