Remarks

If 2 machines are on the same LAN, they can communicate directly: the StreamConfigure function is not required.
If 2 computers are connected to Internet via firewalls (or via boxes for example), the direct communications between these computers are often locked. In this case, StreamConfigure must be used.

Using Conference controls via Internet

Depending on the network typology and on its security parameters (e.g. ports locked by a firewall), it may not be necessary to use a TURN server and/or a STUN server.
Some STUN servers are available in free access.
The TURN servers are not available in free access. You must rent one or create one on Internet.
