yes, but executed by log after 30 seconds after line 84 and immediately hangup.

Note, duration wav file - 4 sec.

the phone you are on does not support early media, 

I don't  hear the audio, because FS don't send RTP traffic to my phone in early media mode (checked sniffers) in my case. 

If dialplans is: 

<extension name="fail_balance">

      <condition field="${blabla}" expression="^\-1$">

        <action application="pre_answer"/>

        <action application="sleep" data="1000"/>

        <action application="playback" data="elight/neg_balance.wav"/>

        <action application="hangup" data="BEARERCAPABILITY_NOTAUTH"/>

      </condition>

 </extension>

then work's fine, no problems (bypass_media=true not set). 

> change your pre-answer before the playback to answer to verify. 

If set answer, problem disappears. But answer it's not for my case.
