>(4xx, 5xx, 6xx) something like the OP:

Obviously Hangup doesn't have this - from a feature stand point, Hangup 
being a channel agnostic application, introducing an "error code" may not be 
desirable.  I can think of one workaround in channels that support SendText: 
use SendText before Hangup.  Today, you'd have to use AGI to ReceiveText, 
but it's a more manageable pain.  However, how to invoke this AGI from the 
origination side can be very challenging.  I can't think of a way right now.
