             Summary: No clean way to stop Playback in Asterisk 13
                 Key: ASTERISK-25661
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25661
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.3.2
            Reporter: Neil L. Decapia


In Asterisk 11, the {{Playback}} application can be terminated by redirecting the channel via the manager {{Redirect}} action. Channel breaks out of {{Playback}}, and {{PLAYBACKSTATUS}} is set to "SUCCESS":

{noformat:title=Asterisk Call Manager/1.3}
Action: Redirect
Channel: SIP/301-00000000
Exten: 3000
Priority: 1
Context: testing-redirect

Response: Success
Message: Redirect successful

Event: VarSet
Privilege: dialplan,all
Channel: SIP/301-00000000
Variable: PLAYBACKSTATUS
Value: SUCCESS
Uniqueid: 1452086660.0
{noformat}

In Asterisk 13, {{Redirect}} still breaks the channel out of {{Playback}}, but {{PLAYBACKSTATUS}} is now set to "FAILED":

{noformat:title=Asterisk Call Manager/2.7.0}
Action: Redirect
Channel: SIP/301-00000000
Exten: 3000
Priority: 1
Context: testing-redirect

Response: Success
Message: Redirect successful

Event: VarSet
Privilege: dialplan,all
Channel: SIP/301-00000000
ChannelState: 6
ChannelStateDesc: Up
CallerIDNum: 301
CallerIDName: Carol
ConnectedLineNum: <unknown>
ConnectedLineName: <unknown>
Language: en
AccountCode: 
Context: testing
Exten: 300
Priority: 1
Uniqueid: 1452086716.0
Variable: PLAYBACKSTATUS
Value: FAILED
{noformat}

Scripts now cannot rely on the result to determine if {{Playback}} did indeed encounter an error or if it was merely stopped, etc.

Asterisk 13 has the manager {{ControlPlayback}} action that can stop playback of a file being played to a channel. However, if {{Playback}} is given more than one file name, then {{ControlPlayback}} only stops the file that's currently playing; {{Playback}} will proceed to play the next file. So {{ControlPlayback}} doesn't really break out of {{Playback}}.

So to have Asterisk 13 cleanly stop {{Playback}}, the regression\(?\) on the {{PLAYBACKSTATUS}} value (Asterisk 11: "SUCCESS", Asterisk 13: "FAILED") should be fixed, or {{ControlPlayback}} should be changed to completely break out of {{Playback}}.
