[Freeswitch-users] vmute not working in passthrough mode

I am doing a conferencing application. I want some members to be video muted when they enter the conference. I tried setting the member-flag vmute. It's working only when the 'video-mode' is set as 'mux'. In 'passthrough' mode, vmute is not working. However member-flag mute is working in both the modes. Will the member-flag vmute work in passthrough mode? Regards, Senthil Ganesh
