So I know its possible to mute auto answered callers, but was wondering if it is possible to auto mute call in video users that call into a meeting. I have multiple Group Series and HDX that call into a DMA Meeting on my RMX. I would like the participants to be automatically placed on mute but not the lecturer. I've tried mute all participants but lecturer but occasionally the joining sites will have Questions and Answers or want to join in on the conversation, plus I'm not sure how to force a specific room to be lecturer. I would also like this done on the endpoints rather than on the RMX if possible.
