Why this matters for digital sovereignty
VoIP and telephony platforms process call metadata and sometimes recordings of customers, which counts as sensitive communication data falling under GDPR and, for critical infrastructure, the NIS2 directive. Check where calls are routed and stored, who ultimately owns the vendor, and whether end-to-end encryption is available.
