Hello,
since I'm not available for today's call (Christoph will step in), here's a short information on how to manage the room:
- Someone needs to dial-in with the room number and the conference manager PIN to open up the room. It's room number and conference manager PIN as one number, followed by # - as usual
- The first conference manager is then asked if the participants should be allowed to speak or not. 1 = not speaking, 3 = speaking. You want to press 3 to allow everyone to speak. 
- *9 will lock the room, so no new parties can join, *7 will mute all participants. You don't need any of these. However, in case you are experiencing issues, like people unable to speak or join, press the according keys again to undo the function (e.g. *9 a second time will unlock the room again, *7 a second time will unmute everyone).
Florian
