Video bridge using Openfire Meetings Plugin + Jitsi Client

Openfire Plugins openfire-meetings

Hello.

I use Openfire 3.10 (Debian7+MySQL+LDAP)

For video I use Openfire plugin Meetings ver.0.1.4 and the Jitsi client ver.2.7.5423.

Tell me responsible for what each of the settings in Openfire plugin Meetings?

Using video link in the Jitsi client not all users can see each other. For example, one user sees two other users, and these two users only see each other, and a third’t see it. The sound works without problems between all clients. What’s the problem?
