<div>hummm, interesting, i was just wondering if it is possible to make a tree shape conferencing bridge which would work something like this.</div><div><br></div><div>1. We will have many freeswitch boxes, each will running a single conference of its own up to say 50 users. These freeswitch box may be geographically distributed as needed, (though it may cause significant latency).</div>
<div><br></div><div>2. Then there is a freeswitch box running on top, all freeswitch boxes dial this top level freeswitch box as normal call. On top level freeswitch these calls will be answered and joined in a single so called top level conference. The second leg of this call will be joined to conference already running in lower level freeswitch boxes.</div>
<div><br></div><div>3. The main speaker / teacher of this virtual class room will just dial to top level freeswitch and join in the top level conference..</div><div><br></div><div>4. For listeners / students of this virtual class to dial in and join, we can setup an OpenSIPs / Kamailio boxes which authenticates users first then forwards call to lower level freeswitch boxes.</div>
<div><br></div><div>5. All student calls will be mute when they join the conference. The teacher / speaker will have a web management interface which will query each lower freeswitch box and generate a participants list. Teacher will be able to unmute any student to listen to their questions etc. and then mute them again to answer the question etc.</div>
<div><br></div><div>What do you guys think? Please suggest.</div><div><br></div><div>Thank you.</div><div><br></div><br><div class="gmail_quote">On Fri, Aug 24, 2012 at 1:15 PM, Stephen Dame <span dir="ltr"><<a href="mailto:sdame@207me.com" target="_blank">sdame@207me.com</a>></span> wrote:<br>
