How to organize and participate in an audio conference:

Please note that:

The audio conference is currently limited to 100 participants
The "headset" button to start the audio will only be displayed in all your rooms but it will only be enabled in those ones with a maximum of 100 members
It is not mandatory that all members of a room have Citadel Conference feature enabled. It is enough that the person who initiates the conference has it. Once the conference is open, the "Join the call" button will be displayed allowing other participants (internal or external) to join it
It is not possible for the moment to invite people from outside your room once the conference has started to join it. Consider inviting them beforehand
It is not possible to switch from an audio conference to a video conference, even if you respect the required number of participants

Organize audio and video conferences with screen sharing
