[asterisk-users] Dial option 'r' not working anymore?

[Vlasis Hatzistavrou]

  Hello,

I have used the Dial option 'r' before in older Asterisk versions and it 
behaved as expected, that is, Asterisk would always give ringback audio 
before the call was answered no matter what.

It has been a while that I have used version 1.4.33.1 without any the 
'r' option. Now that I had to use it for a while, I noticed that 'r' 
would not give ANY audio until the call was answered.

I looked up the documentation of app Dial, but nothing new was 
mentioned, compared to the known 'r' behavior.

I also Googled it, looked through the mailing list, but I couldn't find 
anything to help me. In fact, I noticed that there was a lot of confused 
questions and even confused/confusing answers about the behavior of 'r'.

The extension that I use is pretty simple:

exten => _X.,1,Dial(SIP/${NUMBER}@x.y.z.w,,r,)

Does anyone know if the behavior of 'r' has changed but was not 
documented? If yes, then how does one inject ringback audio before the 
call is answered on the called end?
