For example get asterisk status and send it to the RabbitMQ

<?php

require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;

use asteriskWatch\asteriskWatch;

$amqpConnection = new AMQPStreamConnection($rmq_host, $rmq_port, $rmq_user, $rmq_pass, $rmq_vhost);
$channel = $amqpConnection->channel();
$channel->exchange_declare('_sys_phoneEvent', 'direct', false, true, false);

if (false === ($server = new asteriskWatch($asterisk_host, $asterisk_port, $asterisk_user, $asterisk_pass))) {
	echo "Can not connect to the asterisk\n";
	return;
}
if (getenv('asteriskWatch_debug') != '') {
