Hi, user_3433189!
Welcome to our community!
The unidirectional live broadcast conference can be held when the following devices are included in your videoconferencing solution.
The unidirectional live broadcast conference requires the VP9800 series MCU or CloudMCU.
Only the TE10/TE20, TE Desktop & TE Mobile, Bar 300, Box 300/600, IdeaHub Pro/S/Enterprise, and RoomPresence 65D/65S/75S support unidirectional live broadcast conferences.
