e might have something to do with Circuit Switching. I am guessing that the
CSTele server establishes a virtual switching circuit to the queue server and
trunk server, possibly through a separate network card (servers 3,4 and 5 all
have an extra ethernet card without fixed IP address).

Why would you want to rely on a free stun server which can disappear anytime
when offering commercial services? I would also deploy my own stun servers for
paying customers.

No idea. Maybe the question could be: why have two Asterisk servers?
Perhaps for for redundancy/failover?

No idea. I know BigBlueButton uses Apache MQ & Asterisk but I don't know
the specifics.

No idea.
Good luck!
