Now I know how to do n to n videoconference. But I still have a question. In this way, the n to n conference is implemented by real multicast or by n unicast?

Best Wishes,

No , i'm sorry, rereading my answer makes me see that i wasn't too clear
:)
in fact only one of you have to install the MCU, and preferabily the one
who have the most bandwidth. That's a server, so only one install it,
and then everybody connect to the MCU.
Just notice that you have to launch the MCU before your GM if you are
the one who install the MCU, because both listen to port 1720 for
incoming calls. and you will be warned at GM's startup that your GM
can't listen at port 1720 as it wil be used by the MCU
but just make your friends call the MCU and connect yourself to it and
you'll be able to do n to n videoconf. :)

hope this clearer than the privious answer :)
