Keep the original first
- 01
Preserve the original audio
Keep the complete recording in its received format. Make listening copies or excerpts separately and never present an edit as the original.
- 02
Record complete timing
Keep the date, time zone, called number, displayed caller information, connection time, duration, and how the call ended.
- 03
Write contemporaneous notes
Describe what you observed and what the caller claimed. Mark assumptions, later research, and legal conclusions as separate from the call itself.
- 04
Save written follow-up
Preserve emails, texts, mailed offers, appointment confirmations, websites, terms, and contact details with access dates.
- 05
Track provenance
Use stable filenames and integrity values where available. Record when and how each item was obtained, exported, or shared.
