Issue in turning camera on and off

I am stuck with an issue, really want some advice on this. At my server when a participant turns the camera on/off, their video will be freeze for other participants. Usually, this issue occurs for those who are joining a meeting initiated on a videobridge far from their region (for example- India’s user join the call on US region videobridge)

I think, I need some kind of optimization but don’t know where to start.

@bbaldino @damencho Can you please suggest something?
