[David Dhuyvetter (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=246843#comment-246843 ] 

David Dhuyvetter commented on ASTERISK-28377:
---------------------------------------------

Modified teardown_bridge to be:

def teardown_bridge(channel, outgoing, bridge):
    """Tear down bridge"""
    bridge.removeChannel(channel=channel.id)
    bridge.removeChannel(channel=outgoing.id)
    safe_hangup(outgoing)
    safe_hangup(channel)
    safe_bridge_destroy(bridge)

Same result:
