asterisk users - Jul 2011 - asterisk 1.6 agi problem with PHP

Hello everyone,

I am sure that someone can help with this. We decided to do a fresh install
of asterisk 1.6.2.19

And after we did that, the problem that we have is this - We cant run a
single Php file!

 

Here's the output:

 

    -- Executing [8212 at from-pstn:1] Answer("DAHDI/23-1",

Here's the agi - simple  test that we picked from the net.:

 

#!/usr/bin/php

<?

  ob_implicit_flush(false);

  set_time_limit(6);

  $stdin = fopen('php://stdin', 'r');

  $stdlog = fopen('my_agi.log', 'w');

   $debug = true;

   /* Read input from Asterisk and output via $astOutput */

   function astRead()

   {

              global $stdin, $debug, $stdlog;

      $astOutput = str_replace("\n", "", fgets($stdin,
4096));

      if ($debug) fputs($stdlog, "read: $input\n");

      return $astOutput ;

   }

   /* Write AGI command to Asterisk */

   function astWrite($agiCommand)

   {

      global $debug, $stdlog;

      if ($debug) fputs($stdlog, "write: $agiCommand\n");

      echo $agiCommand."\n";

   }

   /* Handling execution input from Asterisk */

   $agivar = array();

   while (!feof($stdin))

   {

            $temp = fgets($stdin);

            $temp = str_replace("\n","",$temp);

            $s = explode(":",$temp);

            $agivar[$s[0]] = trim($s[1]);

            if ($temp == "")

       {

         break;

            }

   }

          /* Operational Code starts here */

          /* Playback the demo-congrats.gsm file from the

 

    * directory /var/lib/asterisk/sounds/

    */

          astWrite("STREAM FILE /var/lib/asterisk/sounds/en/tt-monkeys
#");

          astRead();

          /* Say the number 123456

          astWrite("SAY NUMBER 123456 #");

          astRead();*/

          /* Finalization of AGI script and clean-ups */

          fclose ($stdin);

          fclose ($stdlog);

          exit(0);

?>

 

 

All help is appreciated.

 

Thanks,

If you try to execute the script as the user running the Asterisk binary 
from the command line, what do you get?

For example:

 	sudo -s -u asterisk
 	/var/lib/asterisk/agi-bin/testera.agi </dev/null

If that executes, I'd take a peek at the environment variables of the 
Asterisk process to ensure /usr/bin/ is in the PATH.

For example:

 	sudo cat /proc/$(pidof asterisk)/environ\
 		| tr '\0' '\n'\
 		| grep PATH

Keep in mind, an AGI interfaces with Asterisk via STDIN and STDOUT so you 
can test an AGI (within obvious limitations) completely outside of 
Asterisk by redirecting STDIN and STDOUT. For example, given a file 
testera.stdin containing:

agi_request: testera.agi
agi_channel: DAHDI/23-1
agi_language: en
agi_type: DAHDI
agi_uniqueid: 1310825293.10
agi_version: 1.6.2.19
agi_callerid: 112686649
agi_calleridname: unknown
agi_callingpres: 3
agi_callingani2: 0
agi_callington: 33
agi_callingtns: 0
agi_dnid: 8212
agi_rdnis: unknown
agi_context: from-pstn
agi_extension: 8212
agi_priority: 2
agi_enhanced: 0.0
agi_accountcode:
agi_threadid: -1223132272

200 result=0
200 result=0
200 result=0

You can execute the AGI like:

 	/var/lib/asterisk/agi-bin/testera.agi <testera.stdin

and your script should display:

 	STREAM FILE /var/lib/asterisk/sounds/en/tt-monkeys #

which, obviously, will not succeed because your AGI is 'talking' to your
shell, not Asterisk.
