Summary:                    Busy()/Congestion() apps don't work in chan-dahdi
with h-extension and priindication=outofband
Description: 
When inbound calls landing on [context] to the extensions 123 or 456, if
h-extension in the same context epsent, BUSY/CONGESTION is successfully
sent to PRI channel.

If h-extension present, BUSY/CONGESTION isn't sent to the PRI channel
until h-extension execution in progress.

Therefore, it's impossible to initiate callback feature by AGI into
h-extension if a reason of drop incoming call is Busy() or Congestion()
application.

Per rmudgett:

I think the reporter for mantis 19008 has a point.  

chan_dahdi basically just sets the softhangup flag and returns when
processing AST_CONTROL_BUSY/AST_CONTROL_CONGESTION in that configuration. 

The builtin Busy() and Congestion() apps then just wait for hangup. 

I think chan_dahdi should queue an AST_CONTROL_HANGUP instead so the wait
for hangup will not happen.
