Record Media stream before answered when dial with "r" opetion

wilfriedtiani · April 28, 2020, 3:54pm

Good morning all,

I created a call file on asterisk which allows me to generate calls automatically without using a sip phone.
Now I would like to be able to send long DTMF access to the connected call but everything I try does not work.

Because the DTMF is not transmitted in the current call.

Can you help me with this problem

THis is my dialplan

[AutoCaller]
exten => _X.,1,NoOp(IN CALL : ${CALLERID(num)} => ${EXTEN})
	;same => n,Dial(SIP/VosWilfried/0033756751100)
	same => n,SendDTMF(**${EXTEN},1500)
	same => n,Wait(10)
	same => n,SendDTMF(*1,1500)
	same => n,Wait(10)
	same => n,SendDTMF(**${EXTEN},1500)
	same => n,Wait(10)
	same => n,SendDTMF(*1,1500)
	same => n,Wait(10)
	same => n,SendDTMF(**${EXTEN},1500)
	same => n,Wait(10)
	same => n,SendDTMF(*1,1500)
	same => n,Wait(10)
	same => n,SendDTMF(**${EXTEN},1500)
	same => n,Wait(10)
	same => n,SendDTMF(*1,1500)
	same => n,Wait(10)
	same => n,SendDTMF(**${EXTEN},1500)
	same => n,Wait(10)
	same => n,SendDTMF(*1,1500)
	same => n,Wait(10)
	same => n,Echo()  
	same => n,Hangup()

and this is the code of my callfile

Channel: SIP/VosWilfried/0033756751100
CallerID: 999
Context: AutoCaller
Extension: 0033756751100

Thank you in advance

This won’t work. You cannot send things this way. It’s actually the other way around. You answer a call and then you send audio. There are a couple of applications like Playback of Send DTMF for that.

With your setup, you basically have no active channels.

ambiorixg12 · April 29, 2020, 6:03am

You can use the M() option to send the DTMF to the called channel

exten=>_*.,1,Noop()
same=>n,Dial(SIP/${trunk}/${EXTEN:1},,M(dtmf))

[macro-dtmf]
exten => s,1,Wait(1)
exten => s,2,SendDTMF(1)
exten => s,3,SendDTMF(2)

Please can you share me a little example wich explain how to do it ?

wilfriedtiani · April 29, 2020, 7:08am

Tks for you answer i will test it rigth now and update you there

david551 · April 29, 2020, 10:15am

The channel is always answered before the extension is run!

If what you are trying to do is to send DTMF as early media, on a single leg call, and there is some reason that encoding it in the dial string can’t be used (this would require using a local channel, to be able to call Dial on the single leg), you could try using a local channel, which answers, before dialing, to trick Originate into thinking that the call is up when it isn’t, and then send DTMF from the extension.

Note I haven’t checked whether SendDTMF supports early media.

Hello all i tried many time and many solution but not work

There is my dialplan

[AutoCaller]
exten => _X.,1,NoOp(IN CALL : ${CALLERID(num)} => ${EXTEN})
	;same => n,SIPDtmfMode(inband|info|rfc2833)
	same => n,SIPDtmfMode(inband)
	;same => n,Dial(SIP/VosWilfried/0033756751652,60,D(wwwwwwwwwwwwww*w*w0w0w3w3w7w5w6w7w5w1w6w5w3wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww))
	same => n,Dial(SIP/VosWilfried/0033756751651,30,M(dtmf))
	same => n,Echo()  
	same => n,Hangup()
	
[macro-dtmf]
exten => s,1,Wait(1)
	;same => n,SIPDtmfMode(inband|info|rfc2833)
	same => n,SIPDtmfMode(inband)

	same => n,SendDTMF(**0033756751653,1500)
	same => n,Wait(10)

#!/usr/bin/php -q

<?php 
	ini_set('display_errors', 1); 
	set_time_limit(30); 
	require('phpagi/phpagi.php'); 
	error_reporting(E_ALL); 
	$agi = new AGI(); 
	$agi->answer(); 
	$agi->verbose("Envoie DTMF 3",3); 
	$agi-> exec("sendDTMF","ww**0033756751655"); 
	$agi->verbose("Fin Envoie DTMF 3",3); 
	$agi->exec("echo","Yesoo"); // $agi->hangup(); 
?>
