When using RealConnect and OTD, how do you admit guests into the Teams meeting for a true OTD/Device free meeting?
I'm just another user, but I can't imagine not having one person on a meeting running the Windows Client. The other option would be to not require a Lobby for the meeting. That would depend on the security needs of your org - but I'm fine with it.
The Poly Mode is pretty good and don't really need a Teams client but everyone's use case is different. For interviews for example, don't really need a laptop but the interviewee woudld be a guest.
If we turn off lobby, it affects all guests in all meetings and is a tenant wide setting. Not ok with that.
