Waiting room management
During the event, moderators can manage the waiting room:

move participants to the waiting room using the
button (a participant with the moderator or operator role cannot be moved), as well as return them to active participation in the conference:

Please note that in the example above, there are participants marked with a "star" icon. This means they are moderators or operators and cannot be moved to the waiting room.
Send DTMF command
In TrueConf Room, you can send DTMF commands to devices that support them directly from the conference control panel using the RTP EVENT and SIP INFO modes. For more details on transmitting these signals, refer to the documentation provided by the manufacturer for the specific model.

There are two options to send DTMF commands:
Option 1
Open the Participants block by clicking the corresponding button.
Click the
button next to the name of the desired participant and select Tone dialing.
Option 2
Open the Change layout block by clicking the corresponding button.
Click on the video window of the participant to whom you want to send a DTMF command and select Tone dial.
Managing and changing participants’ audio and video devices
During a conference, moderators (including the owner and operator) can remotely control the devices of participants. To do this, click the Real-time management button in the conference control panel.
