Teams Security Questions

Hi,

I have done a search on here and have not managed to find a clear answer to if this can be done or not. We are fairly new to using Teams as a teaching platform, I have looked through the policies and think most of them are fairly straightforward, there are a couple of things I would like to know if it is possible before I go looking too deep.

1. Can you disable a user from being able to make calls, but still allowing them to receive calls? I can find a way to remove the call feature completely but that stops me being able to phone them

2. Is there a way to stop users being able to unmute themselves if the organiser mutes all?

3. Is there a way to stop anyone other than a select few from being able to record sessions?

Thanks in advance, sorry if these have been answered before
