The Denmark Data Protection Authority (DPA) ruled on April 11, 2019 that affirmative consent is required when companies record customer telephone calls. Because voice recordings constitute personal data under the European Union’s (EU) General Data Protection Regulation (GDPR), international companies that communicate via telephone with EU customers will need to take steps to ensure GDPR compliance.
In this case, Denmark’s largest telecommunications company, TDC A/S, provided disclosures to its customers that calls may be recorded for training purposes, but the company offered no mechanism for customers to opt-in or opt-out of the recording. During one such call, the customer requested that the call not be recorded, but the service agent said there was no way to turn off the recording. The Denmark DPA rejected the company’s arguments that its recording practices served a legitimate interest, such as the improvement of its customer service, and concluded that the company’s telephone recording practices violated the GDPR.
