How do I make make calls and add the websocket for stream connection?

Hi,

The example in the repo:

plivo-streaming-examples/python/server.py

Lines 135 to 142 in fb92986

	async def xml(request):
	response = ET.Element("Response")
	stream = ET.SubElement(response, "Stream", bidirectional="true", statusCallbackUrl="http://"+config["publicIp"]+"/cb")
	stream.text = "ws://"+config["publicIp"]+"/ws"
	conference = ET.SubElement(response, "Conference")
	conference.text = "ConferenceTest"
	xml_string = ET.tostring(response, encoding="utf-8", method="xml")
	return text(xml_string.decode("utf-8"), content_type='application/xml')

shows a conference resource.

But how to create a call programmatically and attach the websocket connection for streaming? From the docs, it seems plivo takes in an answer_url.
