Definition
Call recording encryption is the process of converting recorded call audio and associated metadata into a coded format that only authorized systems or users can read.
It protects sensitive caller information, including payment details, personal identifiers, and health data, from unauthorized access during storage and transmission.
Any business that records inbound or outbound calls and operates under requirements like PCI DSS, HIPAA, or SOC 2 needs encryption as a baseline control, not an optional add-on.
Encryption typically operates at two points. In transit, calls are protected as audio moves from the phone network to storage. At rest, recorded files are encrypted on the server so a breach of the storage layer does not expose readable audio.
Convirza applies encryption across both layers, backed by 25 years of proprietary call data informing how recording infrastructure is built for compliance-sensitive environments.
