asterisk users - Jun 2004 - Detecting Events in queues

Hi everybody,

I would like to know how can I detect events in queues. For example when
an operator answers a call which was in a queue I would like to  some
informations related to the caller (quote from the database) to the
operator. I saw these events in queuelog.conf but i don't know how to
retrieve them in my AGI.

Thanks for any help
