ami = aio.ami(
    'ip_or_hostname',   // Asterisk PBX machine

    5038,               // the default port number setup
                        // in "/etc/asterisk/manager.conf"
                        // in "general" section

    'admin',            // manager username

    'admin'             // manager password
);

ami.on('error', function(err){
    throw err;
});

ami.on('ready', function(){

    // connected && authenticated

    ami.action(
        'Originate',

agi.on('connection', function(agiHandler){

    // all variables (key, value pairs) are
