jtg0017,
Well DND ON was on the right track just the wrong timer. If you set the Announcement Timer to 60 seconds it will send any call that has been holding for 60 seconds to ring the Chime. The call remains in the queue at its original position, but will continue to ring the chime unless it is sent back. This could become very annoying if you have multiple calls reach the 60 second mark.
Most people use the Announcement and Overflow as RADs when they are waiting to be called, but that is not the only thing they can be used for. The good things is that a call can be pulled back when it is answered by a hunt group member or agent without losing its position in queue.
Thanks,
TE
