If I receive an SDP offer without any ICE candidates from the caller, I
can't use the ICE Agent to perform connectivity checks but I may
sometimes want to use ice4j to setup a TURN relay. Then I would just
put the TURN server IP into my SDP answer in the "c=" line.
Is this possible with the ice4j API?
Could the Agent.nominate() method be used, or does that require the peer
to be responding to checks?
Could a RelayedCandidate be constructed manually perhaps or should it be
done through the Agent class or some other application-facing API?
