Openfire Meeting with Video call

Greetings Everyone,

  I've just installed the Open fire 4.0.2 successfully with plugin Openfire Meetings and Search. Now i want to establish a video conference through our local network using the Openfire application but I can't seem to make it work so i have a couple of inquiries.
  1. Does Openfire meetings with video call can only be accessed using the web browser? if so what is the recommended web browser for this and how to access the web based Openfire meeting session.

  2. Is there any additional plugins that i must install first before i can make it work?

  3. Is there any additional requirement for this to work?

Hoping for your immediate Feedback,
