Hi all,
This is a no matter of this thread, but I need some advice about this.
I have had a question from a client and I don't know from where to start.
This is the question: This client wants to organize video confereces with the purpose of teaching, the matter is which kind of connection is used for this (type of lines), I ask this thinking in speed of transmission, which software is used for this, and if possible which is the best hard to install for this.

Thanks in advance.
