[Freeswitch-users] [Freeswitch-dev] Scaled or distrbuted mod_conference?

[Andrew Cassidy]

Sounds like something I was pondering before too. In theory with a little
playing around you should be able to use 'bridging' conferences on the
'low' boxes to do this.

>From what I can tell, when the first user dials into a low, you can make it
create a new conference call there while bridging in the top level one.

As you're writing in your own moderator controls, you're not going to have
an issue with that, in theory you can query, mute and unmute over ESL or
XML_RPC:
