What's new in TrueConf Server 5.2.7.10218

Mar 9, 2023

Added:

If participants’ camera and microphone were automatically turned off in the conference settings, the menu for controlling AV devices of SIP/H.323 endpoints was not displayed to the conference owner.
Some of the participants could be mistakenly displayed with the “pinned” status for the moderator, who joined the meeting from the web application, if another moderator previously tried to pin these participants in the TrueConf client application but was unable to do it due to the limit on the number of pinned participants on the podium.
