New Revision: 358284

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=358284
Log:
Drop SS7 call if not connected yet when INCOMPLETE/BUSY/CONGESTION.

SS7 is a trunk protocol and should clear a failed call as soon as
possible.

* Made SS7 hangup a call immediately if it has not connected yet for
INCOMPLETE/BUSY/CONGESTION causes.  Otherwise, play an appropriate inband
tone.

(closes issue ASTERISK-19372)
