Thank you to all for your valuable inputs.
See? At first it looks super trivial! And I think it should be. 
Begin troll mode
With Asterisk, using MusicOnHold or Ringing does exactly that.
End troll mode

I will not give up. I don’t want to result to external programming for something like this, although using a little lua script sounds appealing.

If I get it working like I want I’ll post something here.

Ciao!

Ringback is played back only when FreeSWITCH starts an outbound channel - during the bridge command, for example. What Enrah wants, is to play the early media while the dialplan execution goes on, but before the call is bridged.

I tried the following sequence, but it didn't work either: the next command after sleep() was never executed, because the originator timed out after 20 seconds, and the audio file was played during these 20 seconds:

  <extension name="test1">
    <condition field="destination_number" expression="^test1$">
      <action application="pre_answer"/>
      <action application="ring_ready"/>
      <action application="set" data="api_result=${bgapi(uuid_broadcast ${uuid} /opt/sound/ITU-T_P_50_BRITISH_ENGLISH.wav)}"/>
      <action application="sleep" data="10000"/>
      <action application="set" data="api_result=${uuid_break(${uuid} all)}"/>
      <action application="answer"/>
      <action application="playback" data="ivr/ivr-welcome.wav"/>
      <action application="sleep" data="1000"/>
      <action application="hangup"/>
    </condition>
  </extension>


so, it looks like it needs an external application talking over ESL.

use whatever sound file you want as your ringback?
