Hi
@Yinon_BlochCompliant call recording is coming to Teams in early 2020. See the latest Ignite session here
https://myignite.techcommunity.microsoft.com/sessions/831841.) It will be possible to enforce the recordings as shown in the demo via policies
2.) My understanding is that it is stored in third party storage initially so the admin ought to have access to the recordings
3.) It will be a bot that joins the call
Hope that answers your question! Can't wait for this feature to be released.
Best, Chris
