Eric is correct. There is no way to send dtmf while the call has not been answered.

But us very confusing the read command, in specific  option = n(noanswer) to read digits even if the line is not up

My AGI line is the following

The command works, but there is no dtmf negotiation

The command works, but there is a kind of answer
What is the purpose of this noanswer option in a read command when it is imposible to read?.
Is there any way to negotiate with the end user in this early media situation?

Thanks in advance.

Generally the only thing you are allowed to do before answer is send audio.  You can’t receive audio and can’t receive DTMF.   I assume it is to prevent people from doing exactly what you  are trying to do --- trying to have two way communications without paying for the call.

Hi Guys..

I am making an anoucement machine that is not allowed to "answer" the call due to a billing issue.
I found that Playback with "noanwser" is usefull in this case.


But when i request some values to the user with get_data, i think there is an answer anywere.

Is there a way to get_data without answering the call?

Thanks in advance!!
