Financial organisations clinging to ageing voice recording infrastructure may believe inertia is the safer bet. New independent research suggests otherwise.
A Wordwatch survey of 100 compliance, IT and surveillance leaders reveals that the true cost of legacy recorder estates — regulatory, operational and financial — has quietly compounded to a point where standing still is now riskier than modernising.
The research from Wordwatch – put together in a whitepaper – spans decision-makers responsible for communications governance and archiving, identifies six distinct cost lines embedded within legacy estates.
Crucially, these costs rarely appear together on a single budget page, meaning the full picture is almost never visible to the people who need it most. When viewed across a single renewal cycle, the aggregate figure tells a different story.
What the data shows
Despite mounting pressure, 79% of respondents still rely on disconnected recorders and legacy systems for communications governance and archiving — even as more than three-quarters report having faced a regulator’s request for a record in the past year. The disconnect between operational reality and regulatory expectation is stark.
The most cited barrier to change is familiar: 49% of financial organisations point to the risk of migrating historic data as the primary reason they have not yet modernised. Fear of data loss or corruption during migration has long stalled internal conversations about upgrading. But the research argues that calculus has materially shifted in 2026.
Why 2026 marks a turning point
Four developments have converged to change the risk equation. First, the FCA’s August 2025 multi-firm review uncovered 178 confirmed breaches of internal communications policies across 11 wholesale banks in a single year, with 41% implicating directors or senior managers. Third-party vendor failures were explicitly cited as a contributing factor. Second, DORA examinations are now live, with assessors actively scrutinising documented exit plans and sub-processor transparency.
Third, Microsoft Teams has become the de facto voice estate for most regulated organisations, creating a second data silo alongside historic voice recordings that few firms have adequately addressed. Fourth, AI initiatives across the industry continue to stall because communications data remains fragmented across vendors and locked in proprietary formats.
Taken together, these shifts mean that delaying modernisation is no longer a neutral decision. It is, the research contends, a subscription to spiralling cost and accumulating compliance exposure.
Where migrations go wrong — and how to get them right
The report identifies five recurring failure modes in communications data migrations: transcoding that strips evidential value from recordings; broken chain of custody between source and destination; the proprietary export trap that leaves data stranded; leaving legacy infrastructure in place post-migration; and parallel running periods that are cut short before proper validation is complete.
Against these risks, the research sets out what a controlled, evidential-first migration should look like in practice. This includes original-format ingestion to preserve integrity, a full chain of custody documented from source to destination, simultaneous handling of both live and legacy data from day one, and CDR-level reconciliation during parallel running. A phased approach that retires the highest-risk legacy systems first is recommended to manage exposure throughout the transition.
A self-assessment for IT and compliance teams
The research concludes with a twelve-question self-assessment designed to be taken into the next conversation between IT and compliance leaders. It covers four domains: capture and coverage, archive and retrieval, governance and policy, and legacy modernisation readiness. The guidance is direct — if four or more answers require qualification, the cost of remaining static has already exceeded the cost of a properly managed migration.
For IT leaders navigating this moment, the message from the research is clear. The advantage will not go to those with the deepest pockets. It will go to those who act before the compliance clock runs out.
