[asterisk-users] agi get_data noanswer

[Rafael Visser]

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

 $AGI->exec("READ","umenu,VARXX,1,n,2,7");
The command works, but there is no dtmf negotiation

 $AGI->exec("READ","umenu,VARXX,1,,2,7");
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.
