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.

$AGI->exec('Playback',"$message","noanswer")}


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!!

    What you may want to check out is the PlayTones and Ringing applications in your dial plan. Asterisk will answer the call, but your users won't know that because all they hear is the call still ringing. After a certain amount of time passes, you can send them directly to voicemail, hangup, run your scripts, or anything else you want to do with the call. My dial plan snippet looks like this. Just an option.

exten => s,n(ringing),Answer
exten => s,n,PlayTones(ring)
exten => s,n,Ringing
exten => s,n,Wait(${TIMEOUT})
exten => s,n,GotoIf($["${BLOCKDEST}" = "3"]?s-NA-VOICEMAIL,1)
exten => s,n,GotoIf($["${CUSTCALLBLOCKACTION}" = "3"]?s-NA-VOICEMAIL,1) ;
exten => s,n,PlayTones(congestion)
exten => s,n,Congestion(10)
exten => s,n,Hangup

Hi John.

I am making an inteligent annoucement resouce for a big ericsson switch. Is just an ivr with agi applications.

The tricky thing try to make asterisk not to send answer. The perl application with agi commands must be executed with out answering.

Something like

exten => 6009,1,Progress()
exten => 6009,n,Set(__INICIA=${EPOCH})
exten => 6009,n,Set(CHANNEL(language)=sc)
exten => 6009,n,AGI(anouncement.pl)
exten => 6009,n,Hangup()


Thanks anyway.

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.

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.
