Summary:                    Asterisk reports dialstatus as "CONGESTION" when
received a 480 "Temporarily unavailable"
Description: 
Asterisk currently sets the dialstatus to be "CONGESTION" when a 403
"Temporarily unavailable" is received.  It then sends on a 503 "Service
unavailable" to the other party.  For compliance with the RFC I believe
asterisk should be sending back the 480 Temp. unavail to the 3rd party as
it received it and probably should be setting the dialstatus to "NOANSWER"

Previously, if your device was not registered, it would have responded as
you mention below.  It will now use an UNREGISTERED cause code which is
nearly the same as NOANSWER.
