📄️ DTMF obfuscation
The system permits manual obfuscation of calls using a DTMF key sequence at the user's handset. When a user enters a specified sequence of digits, the obfuscation begins, and any audio will be immediately and irreversibly overwritten with the tone specified in the /audio/obfuscation/tones/ section of the settings.xml file. To stop obfuscation, the stop key sequence must be entered, whereupon the audio will be written normally to the call's stream.
📄️ Programmatic obfuscation
Throughout this guide, we will adopt the PCI-DSS example above, where telephone calls that contain spoken credit card information need to be masked out by an audible tone, but only during those parts of the call when the card details are being spoken, leaving intact the rest of the call audio.
