Is it possible to make the chat history for a meeting room permanent? As it currently works, anytime you join a meeting, you only see the chat from the point you joined and forward. Also, if for some reason you drop off the meeting and rejoin, you lose any history. I am aware of the Chat Room functionality, but this isn't available in the lync mobile apps currently, nor can you tie an audio conference call to it, or easily add new users on the fly to the Chat Room. I am trying to create an ongoing meeting place for emergency response situations. To this end, I also need a permenant conference call in number that doesn't require a leader to allow people to enter the room. I have tried creating a dummy account as a designated call in number for first responders, but the call requires a leader. As far as I can tell, you cannot customize your permanent meeting space to allow for anonymous callers to join without a leader.
If these requirements are not possible with the current product, I would like to make a feature request for these things.
