/**
 * This class deals with shenanigans around JVB media session's ICE failed status handling.
 *
 * If ICE restarts are NOT explicitly enabled by the {@code enableIceRestart} config option, then the conference will
 * delay emitting the {@JitsiConferenceErrors.ICE_FAILED} event by 15 seconds. If the network info module reports
 * the internet offline status then the time will start counting after the internet comes back online.
 *
 * If ICE restart are enabled, then a delayed ICE failed notification to Jicofo will be sent, only if the ICE connection
 * does not recover soon after or before the XMPP connection is restored (if it was ever broken). If ICE fails while
 * the XMPP connection is not broken then the notifications will be sent after 2 seconds delay.
