             Summary: ConfBridge doesn't detect disconnect from webrtc
                 Key: ASTERISK-29699
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29699
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip, Core/Bridging
    Affects Versions: 18.7.1
         Environment: Linux asteriskcloudpjsip 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux

            Reporter: Dennis Haney
            Severity: Major


It seems that ConfBridge doesn't detect when the user has crashed/disconnected or otherwise closed the wss connection.

  == WebSocket connection from 'me:1247' closed
    -- Removed contact 'sips:mylogin at me:1247;transport=ws;rtcweb-breaker=no' from AOR 'mylogin at someuniquevalueforyoumachine.mydomain.com' due to shutdown
  == Contact mylogin at someuniquevalueforyoumachine.mydomain.com/sips:mylogin at me:1247;transport=ws;rtcweb-breaker=no has been deleted

Checking state of the confbridge user was in at the time:

Furthermore, Transmit never detects it is sending packets into the void and marks them as dropped.
