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?
