Steps
Start call recording (via TwiML or the REST API) and capture the Recording SID.
When the agent needs to collect sensitive data (e.g., a card number), POST to the Recording resource with Status=paused.
Choose the pause behavior: 'silence' (default, replaces audio with silence to preserve timing) or 'skip' (drops that segment entirely).
After sensitive input is complete, POST Status=in-progress to resume recording.
Retrieve the completed recording — it returns as a single continuous file regardless of how many pause/resume cycles occurred.
Known gotchas
Recordings are billed for their full duration including paused segments, so pausing doesn't reduce cost even though no new audio is captured.
When PCI Mode is enabled at the account level, native/marketplace transcription is unavailable for those recordings — don't wire up a transcription pipeline expecting it to work on PCI-mode calls.
