How to modify the amocrm.php script so that the call goes through both sip and iax ext?

Question

Asterisk

Hello!
I encountered such a problem when setting up amocrm integration with asterisk through the AasteriskNew widget. The script describes the call action (call when you click on a number in the contact card)

elseif ($action==='call'){ // originate a call
        $params=array(
                'action'=>'Originate',
                'channel'=>'SIP/'.intval($_GET['from']),
                'Exten'=>strval($_GET['to']),
                'Context'=>'from-internal',
                'priority'=>'2',
                'Callerid'=>'"'.strval($_GET['as']).'" <'.intval($_GET['from']).'>',
                'Async'=>'Yes',
                // Not Implemented:
                //'Callernumber'=>'150',
                //'CallerIDName'=>'155',
        );
        $resp=asterisk_req($params,true);
        if ($resp[0]['response']!=='Success') answer(array('status'=>'error','data'=>$resp[0]));
        answer(array('status'=>'ok','action'=>$action,'data'=>$resp[0]));

}

But I have phones connected via iax, it doesn't work with them.
How can the script be modified so that the call goes through both SIP and IAX2?
Thank you!
