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).

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