Summary:                    Redirect two bridged channels to the same conference
Description: 
Greetings,

OS: centOS 5.5
Libpri: 1.4.11.4
Dahdi: 2.4.0
Asterisk: 1.8.0

Situation, i have two channels bridged together and i want to pass both
channels to a conference room, so i decided to send a Redirect in the AMI
console:

Action: Redirect
Channel: CHANNEL_1
ExtraChannel: CHANNEL_2
Exten: 1001
ExtraExten: 1001
Context: my_conference
ExtraContext: my_conference
Priority: 1
ExtraPriority: 1
ActionID: XXXX

Sometimes one of the channels fails to stay in the conference, other times
both channels stay in conference (as expected). The AMI events are
different in the two cenarios (the order of the events), when it fails, the
channel that didn't get masquerade is the first to send the MeetMeJoin
event, proceeded by a MeetMeLeave. When it works the first MeetMeJoin is
send by the masquerade channel. I don't know if this order is related to
this issue, but i found it important to report.

Best regards.

P.S.: My conference context is pretty simple...

[my_conference]
exten => _X.,1,MeetMe(${EXTEN},dq)
exten => _X.,2,Hangup

      The channel redirect function (CLI or AMI) hangs up the call instead
of redirecting the call.

      To recreate the problem:
      1) Party A calls Party B
      2) Invoke CLI "channel redirect" command to redirect channel call
leg
      associated with A.
      3) All associated channels are hung up.

      Note that if the CLI command were done on the channel call leg
associated
      with B it works.

      This regression was a result of the fix for issue
https://issues.asterisk.org/view.php?id=16946
      (https://reviewboard.asterisk.org/r/740/).

      The regression affects all features that use an async goto to
execute the
      dialplan because of an external event: Channel redirect, AMI
redirect, SIP
      REFER, and FAX detection.

      The struct ast_channel._softhangup code is a mess.  The variable is
used
      for several purposes that do not necessarily result in the call
being hung
      up.  I have added doxygen comments to describe how the various
_softhangup
      bits are used.  I have corrected all the places where the variable
was
      tested in a non-bit oriented manner.

      The primary fix is the new AST_CONTROL_END_OF_Q frame.  It acts as a
weak
      hangup request so the soft hangup requests that do not normally
result in
      a hangup do not hangup.
