A standard feature of Zendesk Talk is to record calls and create tickets in Zendesk Support which include the recordings as comments on the tickets.
Intelligent Voice transcription for Zendesk Talk creates an additional comment containing the recording and a transcription. If the call contains payment card data then the transcription and the recording in the new comment will be redacted.
Since the ticket now contains both the original comment and the new one added by Intelligent Voice, you can configure Zendesk Support to remove the original comment. The setting for this is in Zendesk Support (under Admin/Channels/Talk/Numbers). We recommend the shortest option, delete after 1 day.
Zendesk have published a guide to these settings here: Managing recording options in Zendesk Talk
