Thanks for your reply (and contributions to a great product).

I only asked because if the parked call goes unanswered, it rings back to the phone that parked the call and keeps ringing. Reading the tip, I understood it to mean in the call goes unanswered, it would continue to the orphaned destination. In our production environment, that is exactly what happens. The person who parked the calls becomes distracted on route to their phone to retrieve the call and the call starts ringing back to the extension where the call was parked and no one is there and no one knows the phone is ringing. The caller gets stuck an is forced to hang up and call back.

This is the extract from the tip. In this case this would be analogous of the parker ignoring the call.

The more useful part of this module is to specify a destination for
parked calls that get orphaned. This can occur if the call is not
picked up and for some reason the original parker can not be reached.
(e.g. the original parker is on the phone and does not have call
waiting or ignores it).
