Send DTMF used to work for us, but since installing
VERSION: 2.0.105 BUILD: 61221-1212
Asterisk 1.2.17

It doesn't work. The logs show that agi-dtmf runs, but no noises come out of it.

Mar 26 12:49:30 VERBOSE[9631] logger.c: -- Executing AGI("Local/8500998@default-a0a6,2", "agi-dtmf.agi") in new stack
Mar 26 12:49:30 VERBOSE[9631] logger.c: -- Launched AGI Script /var/lib/asterisk/agi-bin/agi-dtmf.agi
Mar 26 12:49:30 VERBOSE[9631] logger.c: -- AGI Script agi-dtmf.agi completed, returning 0

Edit: When I use my softphone to dial manually through the same asterisk machine rather than logging in to vicidial then the touch tones work correctly.

More Edit: When I manually call ext 8500998 I do hear the tones, it's just the web gui that doesn't send them.

What version of asterisk-perl are you using?

I have not tested Asterisk 1.2.17 yet.

What version of asterisk-perl are you using?

Do you mean this?

package Asterisk;

require 5.004;

$VERSION = '0.08';

After running this command

asterisk -rx "agi debug"

I see a lot of agi activity, but not from agi-dtmf.

I do not think that the ext that sends the digits is ever called.

[hcobb]

It's difficult to push the debugging much further because the error log fills up with stuff like:

Undefined variable: voicemail_button_enabled in /var/www/vicidial/admin.php on line 562
Undefined variable: voicemail_dump_exten in /var/www/vicidial/admin.php on line 563
Undefined variable: voicemail_exten in /var/www/vicidial/admin.php on line 565

Undefined variable: xferconf_b_dtmf in /var/www/vicidial/admin.php on line 610
Undefined variable: xferconf_b_number in /var/www/vicidial/admin.php on line 614

And so on.

Looking at Apache logs will not help you debug this.

The following solution does not require any AGI scripts:

This solution only works on Asterisk 1.2.X

Remove the following lines from the dial plan:

Code: Select all

exten => 8500998,1,Answer
exten => 8500998,2,Playback(silence)
exten => 8500998,3,AGI(agi-dtmf.agi)
exten => 8500998,4,Hangup


Replace it with the following lines:

Code: Select all

exten => 8500998,1,Answer
exten => 8500998,2,Macro(dtmf,${CALLERID}${CALLERIDNAME})


Also add at the bottom of the dial plan:

Code: Select all

[macro-dtmf]
exten => s,1,GosubIf(${LEN(${ARG1})}=0]?20:10)
exten => s,10,Hangup
exten => s,20,Playback(silence)
exten => s,21,Playback(${ARG1:0:1})
exten => s,22,Macro(dtmf|${ARG1:1})


I implemented this solution at a call center because the first part of DTMF digit seems to be cut off with some SIP phones. This solution solved the problem and is running on a live system.

Does this handle pauses within a DTMF string?(the comma)

[caspar]

Now that you mention it. I do not think it handles pauses. It also does not handle alphabetic characters like a,b,c but it continues to send the digits in the string that it does recognize.

If you enter "1,2" it will play:
1.gsm
,.gsm -> which would produce an error
2.gsm -> which will still play

This is definitely to the best solution, but it is a quick hack to fix things if the AGI scripts does not want to work.

Maybe one can modify the script to check for errors and perform a Wait(1) instead of a Playback(...) if an error occurs.

[mflorell]

I have added ,.wav to the SVN, I'll try to tinker with this later today.
