Call Recordings Redaction

Recording redaction silences sensitive details spoken on a call before the recording is stored. It’s then possible to avoid storing sensitive data from your customers.

Currently, Recording Redaction supports English speech only, and is charged at Deepgram’s speech-to-text rate.

What can be redacted

Choose one or more of these kinds:

Kind	Silences	Examples
`pci`	Card details	Card number, expiry date, security code
`pii`	Personal details	Names, phone numbers, addresses, other identifying numbers
`phi`	Health details	Medications, doses, conditions

Voice API

Set the kinds as a list on any of these:

Call Command	Parameter
Recording start	`redaction`
Dial with `record`	`record_redaction`
Answer call with `record`	`record_redaction`
Bridge calls with `record`	`record_redaction`
Transfer call with `record`	`record_redaction`
Conference recording start	`redaction`

curl -X POST "https://api.telnyx.com/v2/calls/{call_control_id}/actions/record_start" \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "format": "mp3",
    "channels": "dual",
    "redaction": ["pci", "pii"]
  }'

When the recording is ready, the call.recording.saved webhook (conference.recording.saved for a conference) links to the redacted file.

TeXML

`<Start><Recording>`	`redaction="pci,pii"`
`<Dial record="...">`	`recordingRedaction="pci,pii"`
Outbound call with `Record=true`	`RecordingRedaction=pci,pii`
