[asterisk-bugs] [JIRA] (ASTERISK-21859) Confbridge fails when kicking users via end_marked=yes

[Chris Gentle (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=207066#comment-207066 ] 

Chris Gentle commented on ASTERISK-21859:
-----------------------------------------

Yes, I am able to reproduce it without chan_alsa.

Simplifying things even further, I got rid of chan_alsa and chan_local.  I set up a simple [conferences] context and put in the 11.4.0 confbridge.conf sample file (with no edits).  I made two extensions to allow me to call into the conference from two different SIP phones:

{noformat}
  ; admin conference user
  exten => 600,1,Goto(conferences,1000,1)
  ; normal conference user
  exten => 601,1,Goto(conferences,1001,1)
{noformat}

My new [conferences] context is attached.

Dial extension 600 to add the conference leader.  Then dial 601 to add a normal participant.  Then hang up the leader.  The other participant will hear a message that they have been kicked but confbridge list will show that the conference has not been torn down.


{noformat}
Conference Bridge Name           Users  Marked Locked?
================================ ====== ====== ========
1000                                  0      0 unlocked
{noformat}

> I've set up a conference where I'm relying on end_marked=yes to kick all participants when the leader exits.  This results in an error as shown below:
> {noformat}
>  << Hangup on console >>
>     -- <Bridge/0x2364be4-input> Playing 'confbridge-leave.slin' (language 'en')
>     -- Stopped music on hold on SIP/gent_2880-00000002
>     -- <SIP/gent_2880-00000002> Playing 'custom/thank-you.ulaw' (language 'en')
>     -- Executing [1000 at conferences:2] Hangup("SIP/gent_2880-00000002",
> "") in new stack
> == Spawn extension (conferences, 1000, 2) exited non-zero on
> 'SIP/gent_2880-00000002'
> {noformat}
> In this case, the conference leader was the alsa console channel.  Once it was hung up, a non-zero exit status caused the confbridge to go into a bad state showing 0 users:
> confbridge list
> {noformat}
> Conference Bridge Name           Users  Marked Locked?
> ================================ ====== ====== ========
> 1000                                  0      0 unlocked
> {noformat}
> Asterisk has to be restarted to clear this.  In a normal exit, a "confbridge list" would not show conference 1000 because it would have been destroyed.
> If no participants are dialed into the conference, everything closes cleanly when the leader exits.
