asterisk ivr no dealing tone

Question

I am setting up IVR and encountered following trouble there is no dealing tone when client gets to "Dial", it just silently dialing. How to fix this?

exten => s,1,Background(custom/welcome-msg)
exten => s,n,WaitExten(10)
exten => s,n,Dial(SIP/0773,20)

exten => _X,1,Read(NUMBER,,4,n,,10)
exten => _X,n,Dial(SIP/${NUMBER},20)
exten => _X,n,HangUp()

Answer 1

You need add 'r' option in params.

exten => _X,n,Dial(SIP/${NUMBER},20,r)
