asterisk users - Aug 2016 - Dial and start music on hold after timeout

Hello,

I am searching a way to dial a SIP peer, and if it does not answer 
within 20 seconds, play an announcement to the caller. This means that 
the caller would hear a ring tone for 20 seconds, and only then hear the 
announcement if the callee did not answer.

I know it is possible to do this with ARI, but in this particular case I 
do not want to use ARI. I would like to do this purely with dialplan and 
AGI scripts, but I cannot find a way. I have read about the "m" option
of Dial application, but it starts the announcement immediately, whereas 
I would like to start it after 20 seconds of timeout.

Does anybody have an idea ?

Best regards,

Jean Aunis

This seems like the obvious answer but maybe I'm misunderstanding the
question.

exten => s,1,Dial(SIP/alice,20)
 same =>   n,Playback(myannouncement)
 same =>   n,NoOP(Whatever else you want to do goes here)

Sorry, I forgot to write that the SIP peer must keep ringing while the 
announcement is being played.
