How ViciDial works

Hi,
Few months ago I installed ViciDial and run. Feature what I saw about recording on-demand I like. And now I will implement this same way but I am not sure how they do this. There was an something like room where on-demand channel will added if someone will record.
And question is, what tehy use? This is just conference room or what ?

Wrong forum, this is the correct one http://www.vicidial.org/VICIDIALforum/viewforum.php?f=4&sid=9ceaa5ed8503ba07e79ccefb5d8c7843

I doubt they will get an answer there either, as the question isn’t about how to use it, but about its internals.
