[Freeswitch-dev] Scaled or distrbuted mod_conference?

[Muhammad Shahzad]

hummm, interesting, i was just wondering if it is possible to make a tree
shape conferencing bridge which would work something like this.

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).

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.

3. The main speaker / teacher of this virtual class room will just dial to
top level freeswitch and join in the top level conference..

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.

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.

What do you guys think? Please suggest.

Thank you.
