We often have presenters that attend only by phone. Sometimes after their partecipation they keep active the phone call in order to listen to colleague's presentations, and that's caotic because of noises. We can't warn the panelist because he's in call with the session.
Anyone can call the session and disturb the presenter: organizers cannot do anything. We want to keep the possibility for users to use phone call, just in case there are issue with device audio.
If there are any suggestions they will be appreciate, thanks.
