I want to use early media in probably the most typical fashion - I have a few parked DIDs that I'd like to play a message before hanging up the call with a 404. I have no problem accomplishing this with Asterisk but I can't seem to figure this out with FreeSWITCH/FusionPBX. Audio is not heard by the calling party. I have the identical setup using Asterisk and it works properly, so this is not a carrier issue.
Here is my code snippet:
<action application="export" data="call_direction=inbound" inline="true"/>
<action application="set" data="domain_uuid=e32236a8-6845-4d9f-a93f-e3087edea91e" inline="true"/>
<action application="set" data="domain_name=my.domain.com" inline="true"/>
<action application="set" data="bypass_media=false"/>
<action application="pre_answer" data=""/>
<action application="sleep" data="500"/>
<action application="playback" data="/var/lib/freeswitch/recordings/my.domain.com/SIT_NotInService.wav"/>
<action application="hangup" data="UNALLOCATED_NUMBER"/>
And here is the log:
