In UK financial services, voice communications remain central to how business is conducted. As working practices evolve, regulatory risk has expanded beyond traditional telephony. Mobile phones, unified communications (UC), and collaboration platforms such as Microsoft Teams, Webex and Zoom are now firmly within regulatory scope, creating new challenges for IT, cyber, and compliance leaders.

GDPR, and DORA require firms to ensure relevant voice communications are captured, securely stored, and easily retrievable. But how is this achieved without placing additional strain on employees or IT teams?

Compliance gaps in everyday communications

The risk is rarely intentional. Employees default to the tools that help them work efficiently:

• A relationship manager returning a client call on their mobile phone while travelling
• A trader discussing a time-sensitive position over Microsoft Teams
• A senior manager joining calls across multiple devices during a hybrid work week

Without compliant mobile voice recording (MVR) and integrated recording across UC platforms such as Microsoft Teams, these everyday interactions can fall outside surveillance controls, creating significant governance gaps.

The business impact of getting this wrong is significant. For medium and large UK organisations, the average cost of a data breach is now estimated at £3.3 million, with financial services among the most heavily impacted sectors. At the same time, 65% of financial institutions struggle to enforce compliant communications across channels, and nearly half report delays retrieving call recordings when regulators request them.

The solution: Compliant voice recording across every communication channel

A modern compliance strategy brings mobile voice and UC recording together, ensuring policy follows the user rather than the device.

From an employee perspective, nothing changes:

• Calls are made and received as normal
• No recording apps to install, manage, or bypass
• No impact on call quality or user experience

From a compliance and IT perspective:

• All in-scope mobile and Teams voice communications are automatically captured
• Recordings are securely archived and searchable, with AI-powered tools available to accelerate audits and investigations
• Audit trails are consistent across channels, meeting regulatory and operational resilience requirements

This approach removes reliance on user behaviour, eliminates shadow IT risk, and simplifies oversight across increasingly complex communication environments.
