1. Create a log activity to alert you when calls fail.
2. Make an ICR on the destination extension and set it to hang up the call. This way you won't be billed for the test calls.
3. Activate a Dial-IN Call Event on the extension and point it to http://<your_server_ip>/autodial.php

4. Create the autodial.php file as shown below. Mind the ownership and permissions.

   Code Block
   -rwxr-xr-x. 1 voipnow voipnow 357 Jun 16 13:07 /usr/local/vipnow/admin/htdocs/autodial.php

5. This is the code that will be executed once your destination receives the autodialer call. It will save the contents of the Call Event request to autodial.log.

   Code Block
   <?php // set file to write $file = 'autodial.log'; $somecontent = print_r($_GET, TRUE); echo $somecontent;// see sample output below // open file $fp = fopen($file, 'a') or die('Could not open file!'); // write to file fwrite($fp, "$somecontent") or die('Could not write to file'); // close file fclose($fp); ?>

6. Now create the autodial.log file as shown below. Again, mind the file ownership and permissions.

   Code Block
   -rwxr-xr-x. 1 voipnow voipnow 10780 Jun 16 13:47 /usr/local/voipnow/admin/htdocs/autodial.log

7. The calls will be placed by this script (replace with your email address):

   Code Block

   #!/bin/bash cp /tmp/autodial.call /var/spool/asterisk/outgoing/ CALLERID=`cat /tmp/autodial.call | grep CallerID | cut -d "<" -f2 | cut -d ">" -f1` NEWCALLERID="$((CALLERID + 1))" sed -i "s/$CALLERID/$NEWCALLERID/g" /tmp/autodial.call sleep 10 CALLOK=`cat /usr/local/voipnow/admin/htdocs/autodial.log | grep $CALLERID` if [ -z "$CALLOK" ]; then echo "Call with callerID $CALLERID failed." >> /usr/local/voipnow/admin/htdocs/autodial.log echo "Call with callerID $CALLERID failed." | /bin/mail -s "Failed autodial call" example@email.com else echo "Call with callerID $CALLERID was successful." >> /usr/local/voipnow/admin/htdocs/autodial.log fi

The flow

Here is how things should unfold.it goes:

→ The script moves the autodial.call file to the "outgoing" directory.
