Subject: [PATCH] When we change audio device during a cross-protocol
 conference call, it is the first call of the group that will trigger the
 propertyChange to other calls (because every calls share the first call audio
 media device and if the first call is not the first notified, we will end up
 with different audio device amongst the calls).
