Twilio python flask try to get status call back event but it returns "none"

I am new to twilio python and flask. I tried to follow the twilio example for tracking sms status, but as I mentionned I get none as the return for this statement status=request.values.get('callstatus', None).

I want to track the call progress status and see its different status. I follow all the documentation but I am blocked. Thanks for your help.

   from flask import Flask,request
   from twilio.rest import Client
   from twilio.twiml.voice_response import Dial, VoiceResponse
   from pprint import pprint
   import logging
   logging.basicConfig(level=logging.INFO)
   app = Flask(__name__)

   twilioClient = Client('*******************', '*****************************')
   @app.route("/voice")
   def voice():

   call=twilioClient.calls.create(
                    method='GET',
                    status_callback='http://*****.ngrok.io/response',
                    status_callback_event='initiated ringing answered completed',
                    status_callback_method='POST',
                    from_='+**********',
                    to='+*********',
                    url='http://demo.twilio.com/docs/voice.xml''

                    )

        return call.sid


   @app.route('/response', methods=['POST'])
   def outbound():
      status=request.values.get('callstatus', None)
      logging.info('Status: {}'.format(status))
      return ('', 204)



    if __name__ == "__main__":
    app.run(debug=true)

I understand that this is a relatively old post and that you might have figured out the solution as of now, but still I am posting my answer so that it will benefit other users who may face the same issue in future.

There are 2 issues that I can see in the code posted above:

  1. Inside the function voice()

When you are making a request to the twilio server by using the API twilioClient.calls.create(), you are feeding the status_callback_event parameter with a single string.

Instead of passing a single string, you have to pass a list of strings like: ['initiated', 'answered', 'ringing', 'completed']

  1. Inside the function outbound()

The parameter sent by twilio to the call back url is CallStatus and not callstatus. They are case sensitive.

status=request.values.get('CallStatus', None)

You can refer this link to check out all the call resources
