[asterisk-users] how can I catch the event generated when a parked call is hung up?

Hi all,

	how can I catch the event generated when a parked call is hung up?

In my dialplan, when arrives a call to a specific number, Asterisk parks
the call and announces the parking slot to a number. But if the user hangs
up the parked call, I don't know how to catch the event, from dialplan,
that removes the call from the parking slot. I want to know if there is a
method for do this.

Thank you!
