How can I build my own Twiml for outbound calls?

I am trying to build a call center based on Twilio and I wanted to know if we can build out own Call object like below code does in Java: link: https://www.twilio.com/docs/voice/api/call-resource

public class Example { // Find your Account Sid and Token at twilio.com/console // DANGER! This is insecure. See http://twil.io/secure public static final String ACCOUNT_SID = "AC4b0f61f6aaa27a4231e6c03be3488178"; public static final String AUTH_TOKEN = "your_auth_token"; public static void main(String[] args) { Twilio.init(ACCOUNT_SID, AUTH_TOKEN); Call call = Call.creator( new com.twilio.type.PhoneNumber("+15558675310"), new com.twilio.type.PhoneNumber("+15552223214"), **new com.twilio.type.Twiml("Ahoy there!"))** .create(); System.out.println(call.getSid()); } }

I know we can use the URL parameter, but I want to dynamically create a Twiml, rather than use a resource that is going to be static. If we cannot build a Twiml dynamically, and use that to build our call resource, is there any way I can create a dial.xml file dynamically? Source: https://www.twilio.com/docs/voice/twiml/dial Any help would be appreciated.
