public function transferToAgent(){
    $client = $this->init_client();
    $call = $client->account->calls->get($_POST["CallSid"]);
    $call->update(array(            
        "Url" => HTTP_BASE_URL."agent/call_controls/forward_agent?data=".$_POST['agentname'],
        "Method" => "POST"
    ));
}
public function forward_agent(){
    $agentname = $_GET['data'];
    $this->gabbyvilletwilio->AgentTransfer($agentname);
}

function AgentTransfer($agentname){
    $response = new Services_Twilio_Twiml;
    $response->say(
        'Your call is now being transferred to your desired agent.',
        ['voice' => 'alice', 'language' => 'en-GB']
    );
    $dial = $response->dial();
    $dial->client($agentname);
    print $response;
