Parking Lot drops calls

Hi, i have a new phone system that is running freepbx version and asterisk version 1.4.36.

The problem i am having is i can’t route calls back into a queue after the parking lot timer runs up. initially i had calls going back to an 8000 queue, but when the call would ring back it would only go to the person who parked it and not everyone in the queue. so i sent it back to the time condition to see if that would make any difference since that will route the call back into the queue during business hours anyway. however, when i did that any call that timed out would just drop.

does anyone have any idea how to fix this?
