Re: [Asterisk-Users] Asterisk as an outbound call machine?

[Jim Archer]

Hi Ken and thanks!  That's great!  I had never heard of the superdialer app 
for Asterisk.  I'm not sure what you mean by predictive dialing.  But we 
can write php code to go through the database.

I need to get this thing to run unatended.  Is it possible for Asterisk to 
recognize busy signals and answering machines?  I realize answering 
machines are tricky, but can it at least detect silence?

Thank you!
Jim

Jim,
What you are probably looking for is a superdialer mechanism, as it is
tricky to get Asterisk to do predictive dialing.
A superdialer (if you don't know what it is) is basically a forward call
succession plan. What happens is that you connect to one phone number
after another in successive order, with your agent sitting and listening
on one end.
Accomplishing this in Asterisk is fairly easy, and I approached a
similar problem with an AGI script (written in PHP to interface with our
database).
All you would need to do is have an agent connect to a specific
extension and then launch the AGI script. Here's something off the top
of my head:
------------ extensions.conf ------------
exten => 5000,1,Wait(1)
exten => 5000,2,Answer
exten => 5000,3,AGI(superdialer.php,${INSERT_SOME_PARAM_HERE})
exten => 5000,4,Hangup
------------ superdialer.php (using PHP AGI) ------------
<?php
require_once('phpagi/phpagi.php');
require_once('AwesomePhoneNumberSelectCode.inc.php');
$agi = new AGI();
$numbers = AwesomePhoneNumberSelectCode_Execute();
// assume it returns an array of phone numbers
foreach ($numbers as $number) {
        $agi->conlog("SuperDialing: $number");
        // dial with a 30 second timeout (approx. 5 or 6 rings)
        $result = $agi->agi_exec("EXEC Dial
IAX2/[EMAIL PROTECTED]/$number|30");
        if ($result['code'] != 200) {
                // error here
        }
       $result = $agi->agi_exec('channel status');
       if (!is_array($result) || $result['code'] != 200) {
        // asterisk terminated on us, so exit out
              break;
       }
}
?>
Something like the above should allow you to accomplish what you're
looking to accomplish.

Hi All...
I have a need to phone a large number of people and collect information
from them.  I know Asterisk has a nice IVR system, but can it be used to
initiate a call to people listed in a database or text file?
Don't worry, this is not an annoying marketing thing.
Thanks...
