[Freeswitch-users] Question about large confeerence

Fri Apr 20 17:15:31 UTC 2018

a conference with 1000 members demands huge resources... and this is not
efficient if only 2-5% of members will actually talk.
you need to keep the actual conference to the minimum number of "speakers"
and move listeners to a streaming "service".

so, focus on how to get your entire conference streamed somewhere.

another thing to consider.... do the "listeners" really need to be in time
sync with the conference ? They will just hear the conversation from the
conference a bit later... thats all.
