             Summary: Occasional audio failure after placing call on hold
                 Key: ASTERISK-20642
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20642
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 11.0.0
            Reporter: Jeremy Pepper


I've run into an intermittent issue placing calls on hold: when they're taken back off hold, the call's audio does not resume.

I have encountered this issue without explicitly trying; however, reproducing it reliably is a bit of a pain. I've been placing a call through the system to another server on our network that acts as a test target. I'll rapidly hold and unhold the call until the audio goes dead. Right as the problem occurs, Asterisk logs this:

{noformat}    -- Started music on hold, class 'default', on SIP/TheAnswer-00000003{noformat}

That message doesn't appear before then. Repeating the same procedure (cycling hold and unhold) eventually brings the call audio back.
