I am creating some kind of monitoring for callcenter. Found one thing. Whan a Caller (Memeber) joined queue 1, then member-queue-start event appears. But if caller left the queue, and joined in a few minutes later (discard_abandoned_after = 3600) the same queue, then member-queue-start event is not shown. Maybe it is right but how can I find out  if memeber rejoined the queue? --
