[asterisk-users] Dealing with progress codes

[Juan Rodríguez]

Try using a R or r on the Dial command, the R option is better for you in my
opinion.
i.e Dial(Zap/G2/1${EXTEN},30,R) or Dial(Zap/G2/1${EXTEN}|30|R)

The R option is going to generate a ring tone when the callee indicates
ringing and is going wait for an Answer. As Progress is just for early
media, you wont get that message.

For more info on the Dial command see:
