<body>By the way, I wonder now!<BR>
If people are videoconferancing, is it better to have<BR>
1- a softphone capable of showing everybody, which means one window for each one that is <FONT class=""><FONT class="">talking.</FONT> (what would happen with current <FONT class="">hardphone that have only one screen)</FONT></FONT><BR>
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 <FONT class="">great, is it really worth it or after 4 people it would just look like 1 pixel for each head we see)</FONT><BR>
3- everybody see the one that talks. So if you want people to see you, you have to be louder that the otherone!<BR>
<BR>
4- any other idea ?<BR>
