• a call goes into an IVR
• there it is answered
• then I want to forward the call to another number via uuid_transfer
• a new transfer dialplan is then generated
• I want to issue a ringback sound file to the caller, in order to show that the call is not hung up
  
• I just don't get the ringback to work properly
  

That's what I did
       <action application="set" data="transfer_ringback=local_stream://moh"/>
This does silence for some seconds, and then when the transfer extension is ringing, plays MOH. So the caller may assume for some seconds that the call is hungup before MOH plays.

       <action application="displace_session" data="local_stream://moh"/>
This also does silence for some seconds, and then when the transfer extension is ringing, plays MOH. So the caller may assume for some seconds that the call is hungup before MOH plays.

I also tried the ringback application with no better result.

So how can I play a background sound for the time

• after transfer
• and before the ringing/progress message is received?
