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 #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.

|

<para>The calling extension, context, and priority are stored in <variable>MACRO_EXTEN</variable>,
|
|
<variable>MACRO_CONTEXT</variable> and <variable>MACRO_PRIORITY</variable> respectively. Arguments
|

become <variable>ARG1</variable>, <variable>ARG2</variable>, etc in the macro context.</para>

<para>If you Goto out of the Macro context, the Macro will terminate and control will be returned

<para>If <variable>MACRO_OFFSET</variable> is set at termination, Macro will attempt to continue

at priority MACRO_OFFSET + N + 1 if such a step exists, and N + 1 otherwise.</para>
|
|
<warning><para>Because of the way Macro is implemented (it executes the priorities contained within
|
|
it via sub-engine), and a fixed per-thread memory stack allowance, macros are limited to 7 levels
|
|
of nesting (macro calling macro calling macro, etc.); It may be possible that stack-intensive
|
|
applications in deeply nested macros could cause asterisk to crash earlier than this limit.
|
|
It is advised that if you need to deeply nest macro calls, that you use the Gosub application
|
|
(now allows arguments like a Macro) with explict Return() calls instead.</para></warning>
|
|
<warning><para>Use of the application <literal>WaitExten</literal> within a macro will not function
|
|
as expected. Please use the <literal>Read</literal> application in order to read DTMF from a channel
|

currently executing a macro.</para></warning>
