Broken hangupcause passtrough
-----------------------------

                 Key: ASTERISK-20291
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20291
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_dial
    Affects Versions: 1.8.15.0, 1.8.16.0
            Reporter: Konstantin Suvorov


Setup: [PBX1] -- IAX2 -- [PBX2]
When you dial from PBX1 with 'g' option, and execute Hangup(custom-cause-code) on PBX2, custom-cause-code will NOT be set to HANGUPCAUSE variable on PBX1.

PBX1 dialplan excerpt:
...
same => n(dial),Dial(IAX2/${LOGIN}:${PASSWORD}@${HOST}:${PORT}/client,5,g)
same => n,NoOp(Hangup cause: ${HANGUPCAUSE})
...

PBX2 dialplan excerpt:
...
same => n,Hangup(1)

In this setup you will get hangupcause=16 instead of expected 1.

I think this is caused by misplaces 'else' statement in app_dial.c (Revision: 369258, Line 2999) after 1.8.15.0 update.
In 1.8.13.0 (and I think in 1.8.14.x) it was OK.

Please fix this, cause this breaks advanced phone routing schemes.
