In all the ice4j examples (for example) the agent is set to setControlling(true) for one site and setControlling(false) for the other site.
Which value must I set if the other site is a browser? I can modify it only on the Java site in this case. Or is there an equivalent in JavaScript? Can I derive this from a SDP offer or answer? Depends this on the attribute a=setup:active
and a=setup:passive
?
