[asterisk-users] Confbridge doesn't kick chan_local

[Chris Gentle]

I have a confbridge setup that feeds the conference from the ALSA
microphone input (this is the conference leader) and then uses
app_ices to send the conference audio to icecast.

I start the conference leader like this:

console dial 1000_admin at conferences

I join the ices user to the confbridge with a call file:

Channel:  Local/1000 at conferences
MaxRetries: 2
RetryTime: 60
WaitTime: 30
Context: conferences
Extension: 1000_ices
Priority: 1

This all seems to work great until I need to kill the conference.  My
confbridge user profile sets all users up with end_marked=yes so that
they should be kicked when the leader exits.  The Local channel
doesn't seem to exit properly:

<< Hangup on console >>
    -- Stopped music on hold on Local/1000 at conferences-00000000;2
    -- <Local/1000 at conferences-00000000;2> Playing

    -- Executing [1000 at conferences:2]
Hangup("Local/1000 at conferences-00000000;2", "") in new stack
  == Spawn extension (conferences, 1000, 2) exited non-zero on
'Local/1000 at conferences-00000000;2'
  == Spawn extension (conferences, 1000_ices, 4) exited non-zero on
'Local/1000 at conferences-00000000;1'
[Jun  3 07:44:27] NOTICE[18237]: pbx_spool.c:402 attempt_thread: Call
completed to Local/1000 at conferences

The bridge gets left in an odd state.  Rather than the bridge being
destroyed, a "confbridge list" shows the conference is still active
with 0 users.  I have to restart asterisk to clear it.

I wonder if someone might take a look at my dialplan snippet below and
see if I'm doing something wrong before I file a bug report.  I'm
using Asterisk 11.4.0.
