Getting "Application error" voice message

Hi ,

We are trying IRIS & Oncall in our office environment. Whenever I create a test incident (Using Plans) with urgent priority, I get a call from iris. But the voice message says "application error". I expect the voice call to read the incident. It is not working. I have opened the externalip:16649 to the world, Below is my twilio config in IRIS,

vendors:

• type: iris_twilio
  name: twilio_1
  account_sid: XXXXXXXXXXXXXXXXXXXXXXXXX
  auth_token: XXXXXXXXXXXXXXXXXXXXXXXXX
  twilio_number: +XXXXXXXXXXXXXXXXXXXXXX
  relay_base_url: http://External-IP:16649/

I get the following error,

web.1 | 54.158.131.187 - - [24/Jan/2018:05:24:26 +0000] "POST /api/v0/twilio/calls/gather?content=188.+test_call&source=Autoalerts&instruction=Press+2+to+claim.&message_id=188&loop=3 HTTP/1.1" 404 - "-" "TwilioProxy/1.1"
web.1 | 54.82.193.204 - - [24/Jan/2018:05:24:28 +0000] "POST /api/v0/twilio/status HTTP/1.1" 404 - "-" "TwilioProxy/1.1"
web.1 | 54.165.215.242 - - [24/Jan/2018:05:24:30 +0000] "POST /api/v0/twilio/status HTTP/1.1" 404 - "-" "TwilioProxy/1.1"

Please help me fix it.

Thanks,

Start by reproducing the urgent-priority call through the configured Twilio relay and inspect the logged POST requests to /api/v0/twilio/calls/gather and /api/v0/twilio/status. Trace why both endpoints return 404; done means the call returns the incident message and the Twilio callbacks no longer produce 404 responses.
