Dynamic Queue Agents

The "Dynamic Queue Agents" application in MikoPBX is a feature designed to enhance the flexibility and efficiency of call center operations.

From time to time there is a need to add and remove employees from the queue. Until now, this was only possible to do through the web interface of the telephone exchange.

In this article I will tell you how to implement the ability to connect and disconnect from a queue by dialing a service extension number.

  1. Create a new queue with a four-digit extension number. For example, 2001. (see documentation “Call Queue”)

  1. Describe the new “Dialplan Application”

  1. Assign a “Extension to call the application” - 999XXXXX, you can redefine the first three digits with your own combination

Code type - “PHP AGI script”

  1. In the "Programme code" tab, paste the following content:

<?php

use MikoPBX\Common\Models\CallDetailRecordsTmp;
use MikoPBX\Common\Models\CallQueueMembers;
use MikoPBX\Common\Models\CallQueues;
use MikoPBX\Common\Models\Extensions;
use MikoPBX\Core\Asterisk\AGI;
use MikoPBX\Core\Asterisk\Configs\QueueConf;

require_once 'Globals.php';

$agi = new AGI();
$agi->answer();

$extension = $agi->get_variable("CHANNEL(peername)", true);
if(empty($extension)){
    $extension = $agi->get_variable("CALLERID(num)", true);
}
$q_exten   = substr($agi->request['agi_extension'], 4);
$add_agent = substr($agi->request['agi_extension'], 3, 1);

$agi->noop("$extension $q_exten $add_agent");

$res = Extensions::findFirst("number='{$extension}'");
if(!$res){
    // Error, such extension number does not exist.
    $agi->hangup();
}
$res = CallQueues::findFirst("extension='{$q_exten}'");
if(!$res){
    // Error, such queue does not exist.
    $agi->hangup();
}
$a_count = CallQueueMembers::maximum([ "queue='{$res->uniqid}'", 'column' => 'priority'] ) + 1;
$member  = CallQueueMembers::findFirst("queue='{$res->uniqid}' AND extension='{$extension}'");

if($add_agent === '1' && !$member){
    $member = new CallQueueMembers();
    $member->extension  = $extension;
    $member->queue      = $res->uniqid;
    $member->priority   = $a_count;
    $member->save();
    QueueConf::queueReload();
}

if($add_agent == false && $member){
    $member->delete();
    QueueConf::queueReload();
}

$linkedid = $agi->get_variable("CDR(linkedid)", true);
$res = CallDetailRecordsTmp::find("linkedid='{$linkedid}'");
foreach ($res as $data){
    $data->delete();
}
sleep(2);
$agi->hangup();

Press "Save settings"!

Now "Dynamic queue agents" application is ready to use 🎉.
