How many connections can we have in classroom mode of Licode

Hi all,

I see that Licode have the classroom mode (described
here http://chotis2.dit.upm.es/room?id=52a71a57dfb052994400007c)
I wonder how many connections we can have with this mode (1 room)
I have read a thread about maximum of 12 connections, but still in
discussion and there no conclusion now
