Summary:                    Hangup cause 20 (subscriber absent), clearly an end
user condition, is being used for unregistered trunks
Description: 
In a similar context to http://bugs.digium.com/view.php?id=14683, calls to
trunks which are unavailable due
to a qualify failure are being given hangup cause 20 (subscriber absent). 
This is clearly intended to cover mobile subscribers currently off the
network, and unregistered SIP phones, which are not conditions that will
succumb to immediate retries over a different route.

3 (no route to destination) or 38 (network out of order) would seem more
appropriate for a trunk, although I think that would also require some
mechanism to distinguish trunks from leaf connnections.

You can check in the dialplan with the SIPPEER() function and by using
hangup with an argument send any cause code you like - instead of sending a
dial() to test the call.
