Hm i just noticed that if you want to use the agi.. you have to watch out as everything in square brakets are displayed as linik
so if you want to use ti you have to reverse this.. so in function write_rates
change the set_var('DESTINATION'.$i,$rate"destination");
and so on .. to $rate and then the square braket and then "destination" squarebraket
...
this should help i think

This didn't work for me either, even with the AGI in place still wasn't getting the least cost being returned.

My C knowledge isn't good 'nuff to work out why but I think it's something to do with it not correctly working out which is actually cheapest and therefore just throwing the records into memory in the order they are read from the database.

Changing the SQL statement on line 1748 in file 'rate_engine.c' the one before 'table_cost);' from ....

'FROM %s'

to ....

'FROM %s ORDER BY prefix, (startcost + periodcost) / (firstperiod + periods) DESC'

seems to make it work!!!!

Perhaps not the most idea way or working out the cheapest but works for my purposes.

oh i will just include that here.

and in the dial plan ...

so after some closer tlook at this addon i got it finally to work. Note that this won't sort (:exclaim:)
the rates for you , you have to write an script which would do that.
here is my php agi (it took me a full day fo figure out that this actually don't sort


require "phpagi.php";
//include('/etc/asterisk/config.php');
ob_implicit_flush(true);
global  $agi;
$agi = new AGI();
 set_time_limit(5);

 error_reporting(0);
//L:wq$in = fopen("php://stdin","r");

$debug=false;

 $avglen=300;

function load_rates() {
global $agi;
$j=0;
for ($i=1 ; $iget_var('DESTINATION'.$i);

$firstlen=$agi->get_var('FIRSTLEN'.$i);

$restlen=$agi->get_var('RESTLEN'.$i);
$startcost=$agi->get_var('STARTCOST'.$i);
$periodcost=$agi->get_var('PERIODCOST'.$i);
$trialcost=$agi->get_var('TRIALCOST'.$i);

 if (isset($destination) ) {
$j   $ecost = calcaveragecall($firstlen, $restlen,$startcost,$periodcost);

$tmp = array("destination"=>$destination,"firstlen"=>$firstlen,"restlen"=>$restlen,"startcost"=>$startcost,"periodcost"=>$periodcost,"trialcost"=>$trialcost,"ecost"=>$ecost);
 $rates$j = $tmp;

$agi->con_print_r($tmp);
}
}

return $rates;
}



 function calcaveragecall($firstlen, $restlen,$startcost,$periodcost){
global $avglen,$agi;

  if ($firstlen >= $avglen ){

      $estimatecost = $firstlen/$restlen * $periodecost;}
 else{
   $estimatecost = ($avglen/$restlen) * $periodcost;


}
$estimatecost += $startcost;
$agi->con_print_r($estimatecost);
   return $estimatecost;
}

function write($line) {
  global $debug, $stdlog,$agi;
  if ($debug) fputs($stdlog, "write;"> $line\n");
  echo $line."\n";
}

 function write_rates($rates){
 global $agi;
 $agi->con_print_r($rates);
 $i=0;

 foreach ($rates as $rate){
 $i;
 $agi->set_var('DESTINATION'.$i,$rate"destination");
$agi->set_var('FIRSTLEN'.$i,$rate"firstlen");
$agi->set_var('RESTLEN'.$i,$rate"restlen");
$agi->set_var('STARTCOST'.$i,$rate"startcost");
$agi->set_var('PERIODCOST'.$i,$rate"periodcost");
$agi->set_var('TRIALCOST'.$i,$rate"trialcost");
$agi->set_var('ECOST'.$i,$rate"ecost");

}


 }
 function read() {
 global $in, $debug, $stdlog;
 $input = str_replace("\n", "", fgets($in, 4096));
 if ($debug) fputs($stdlog, "read: $input\n");
 return $input;
}



function array_sort($array, $key)
{
  for ($i = 1; $i con_print_r($sortedrates);
 write_rates($sortedrates);

exit;

it is not really a nice script but it will work. any updates welcome
next you have to fill the database
so for using for instance voipjet



| route_id | provider_id | technology | peer | pattern | substitute | description |

| 1 | 3 | IAX2 | XXX@voipjet | 00 | 011$1 | try |

which would subtitute 00 with 011 and adds IAX2/XXX@voipjet/011
not tha you would have to add adifferent line to egress if you wanna
dial to the us .

next an exampel for the rate feed

| rate_id | route_id | iso | type | country | extra | prefix | active_date | expires_date | firstperiod | periods | startcost | periodcost | trialcost |

| 9 | 9 | 1 | | usa alaska | | 001907 | 0000-00-00 | 0000-00-00 | 0 | 1 | 2980 | 0 | 0 |
| 10 | 9 | 1 | | usa hawaii | | 001808 | 0000-00-00 | 0000-00-00 | 0 | 1 | 2980 | 0 | 0 |
| 95 | 9 | 1 | | usa proper | | 001 | 0000-00-00 | 0000-00-00 | 0 | 1 | 2980 | 28 | 0 |
| 2594 | 3 | 1 | | usa alaska | | 001907 | 0000-00-00 | 0000-00-00 | 6 | 6 | 0 | 197 | 0 |
| 2595 | 3 | 1 | | usa hawaii | | 001808 | 0000-00-00 | 0000-00-00 | 6 | 6 | 0 | 161 | 0 |
| 2596 | 3 | 1 | | usa proper | | 001 | 0000-00-00 | 0000-00-00 | 6 | 6 | 0 | 130 | 0 |

so for the route_id you would have to use the key from the egress table.
that will make it work
the extra column is actually for the identifier mobile or proper but i still have not done the work . to make that happen
so maybe this will help you save some time .. (:biggrin:)
i would have appreciate it..

I know that many people have tried this, but has anyone ever made it work?

Have anybody an example for rate-engine e.g. extensions.conf with database-entrys?

I'd like to see a PostgreSQL version of this.
