Hi, I expect this topic has already been addressed in this maillist.
But it not, I would like to comment that ICE does not work when both
peers are behind symmetric NAT (very common in home routers).

In that case, the only solution is to use TURN by adding it the last
candidate in the ICE SDP, but TURN requires authentication and, of
course, a TURN server.

Has been this topic discussed? If the website supposed to provide the
WebRTC client with information about which TURN server to use and
username:password for using it?

Thanks a lot.
