[Asterisk-video] vdo conf

[Ramtin Amin]

By the way, I wonder now!
If people are videoconferancing, is it better to have
1- a softphone capable of showing everybody, which means one window for each one that is talking. (what would happen with current hardphone that have only one screen)
2- a softphone that has a single window but the pbx that sends a gride with the video of everybody in it ? (Since the video resolution is not that great, is it really worth it or after 4 people it would just look like 1 pixel for each head we see)
3- everybody see the one that talks. So if you want people to see you, you have to be louder that the otherone!
 
4- any other idea ?
