@Nikita Kuzmin Thank you for your question about ACS SDK support for calling transcripts.
We had another customer ask this question back in November 2021 and the answer we received is that transcripts are not currently supported within the ACS Calling SDK. This is a feature they're looking into but there is no ETA to share for further updates.
We have flagged this feedback though and will share it again in our next meeting with the product group since this has now been a repeated feature request.
