Transcription status callback
Payload sent by SignalWire to your Transcription Status Callback URL when the status of a transcription changes.
Configure this callback by enabling transcription on a recording via the
[Record](/docs/compatibility-api/cxml/reference/voice/record) verb (`transcribe=true`) and setting `transcribeCallback`
to your webhook URL.
Your app can use these parameters to handle the transcription — for example, uploading the text to
your CRM, sending it via email, or forwarding the body via SignalWire SMS.
