Call Parking Cucatom Element is available for download in http://developer.cisco.com/web/cvp/download
 
This CVP Call Studio custom element enables meet-me scenarios to be implemented by allowing the caller to be parked/registered on a specified number in order to receive incoming pick-up calls. It is suited to situations in which a waiting-caller notification is broadcast to solicit someone to pick-up the call rather than transferring the call explicitly to a known destination.
