Unable to connect another Active User while connected

[JOOKER69]

Hello,

at first, your script is great, i'm realy new in webrtc and node and it helps me to learn it, THX!
but...

how can I connect to another user from the Active Users list, while allready connected?
I mean disconnect the current one and connect to the another one... like:

I'm SocketId AAA...
then
Click on Active Users list SocketId BBB,
Connecting to SocketId BBB,
Connection established from AAA to BBB and Video for both is present.
then
Click on Active Users list SocketID CCC
Stopping connection/video from/to SocketId BBB,
Connecting to SocketId CCC,
Connection established from AAA to CCC and Video for both is present.

Any idea?

Thanks
