Financial organisations clinging to ageing voice recording infrastructure may believe inaction is the safe option — but independent research published in 2026 suggests the opposite is true.
A Wordwatch study of 100 compliance, IT and surveillance leaders reveals that the real cost of legacy recorder estates extends well beyond maintenance budgets, touching regulatory exposure, operational fragility and stalled digital transformation programmes.
The research from Wordwatch – put together in a whitepaper – examines why modernisation efforts so frequently stall, identifies a common friction point: 49% of financial organisations cite the risk of migrating historic data as their primary barrier to change. Many IT and compliance teams have either witnessed or experienced a problematic migration first-hand, and that institutional memory continues to shape decision-making. In 2026, however, the calculus is shifting.
Four forces reshaping the decision
Four significant developments over the past twelve months have altered the risk profile of doing nothing. First, the Financial Conduct Authority’s August 2025 multi-firm review uncovered 178 confirmed breaches of internal communications policies across 11 wholesale banks in a single year — 41% of which involved directors or senior managers. The review explicitly identified third-party vendor failures as a contributing factor, raising questions about organisations still dependent on ageing infrastructure.
Second, Digital Operational Resilience Act examinations are now live across the European Union, with assessors actively scrutinising documented exit plans and sub-processor transparency. Third, Microsoft Teams has become the de facto voice platform for most regulated organisations, creating a new data silo that sits alongside — rather than integrating with — historic voice archives. Fourth, AI-driven initiatives across the sector continue to stall on communications data that remains fragmented across vendors and locked in proprietary formats.
Taken together, these shifts mean that inaction is no longer a neutral position. Legacy recorder estates carry a subscription cost in the form of spiralling maintenance fees and compounding compliance exposure.
What the research found
Despite these pressures, 79% of organisations surveyed still rely on disconnected recorders and legacy systems for communications governance and archiving. This figure is particularly striking given that more than three-quarters of respondents reported receiving a regulator’s request for a record in the past year alone.
The study maps six distinct cost lines embedded within a legacy estate — most of which never appear together on a single budget page — and examines what they compound to over one renewal cycle. It also identifies five ways communications data migrations typically go wrong: transcoding that strips evidential value, broken chain of custody, proprietary export lock-in, failure to retire legacy infrastructure post-migration, and parallel-running periods cut short before proper reconciliation.
What a controlled migration looks like
The research sets out what an evidential-first migration should include: ingestion in original file formats, a full chain of custody from source to destination, live and legacy data in scope from the outset, genuine parallel running with call detail record-level reconciliation, and a phased approach that prioritises the retirement of highest-risk legacy systems first.
The report also includes a twelve-question self-assessment covering capture and coverage, archive and retrieval, governance and policy, and legacy modernisation readiness. Organisations that find themselves qualifying four or more answers are, according to the research, already past the point at which the cost of standing still exceeds the cost of a controlled migration.
The message from the 2026 research is pointed: the IT leaders who navigate this most effectively will not necessarily be those with the largest budgets. They will be those who ran a controlled, evidence-preserving migration before regulators forced the issue.
