Twilio Channel API's not working

Rasa Pro CALM
1

I believe that my “twilio_voice” endpoints are not working properly, and it’s not clear to me whether they even exist at all.

Right now, my traditional REST API’s appear to be working properly, and interacting with my chat flow – evidenced by:

curl  -X POST   'http://xx.xx.xx.xx:5005/webhooks/rest/webhook'   --header 'Content-Type: application/json'   --data-raw '{
  "sender": "test_user",
  "message": "course survey"
}'
[
   {"recipient_id":"test_user","text":"Welcome to this online course survey. On a scale of 1 to 5, how much do you agree that blah blah blah?"}
]

These CURLS are very quickly getting responses from the webhooks/rest/webhook endpoint. However, when I try any CURL to webhooks/twilio_voice/webhook endpoint, it either fails with an error 404 or timesout.

curl  -X POST   'http://xx.xx.x.xx:5005/webhooks/twilio_voice/webhook'  --header 'Content-Type: application/json'   --data-raw '{
  "sender": "test_user",
  "message": "course survey"
}'

{
    "description": "Not Found",
    "status": 404,
    "message": "Requested URL /webhooks/twilio_voice/webhook not found"
}

or if I send to the secure https:// version of that same endpoint,

curl  -X POST   'https://xx.xx.x.xx:5005/webhooks/twilio_voice/webhook'  --header 'Content-Type: application/json'   --data-raw '{
  "sender": "test_user",
  "message": "course survey"
}'

it times out after 30 seconds.

As you would expect, Twilio also fails when it tries to contact this.

My credentials.yml includes the following:

twilio:
  account_sid: "AC92ac1a1a5axxxxx99653b"
  auth_token: "73427539cd56e32xxxxxxxc59953"
  twilio_number: "+1608xxxxxxx"

twilio_voice:
  initial_prompt: "hello"
  assistant_voice: "woman"
  reprompt_fallback_phrase: "I didn't get that could you repeat?"
  speech_timeout: "5"
  speech_model: "default"
  enhanced: "false"
  • Is there something else I need to be configuring beyond credentials.yml to get it to deploy endpoints?
  • I don’t see any documentation for what the Rasa Twilio API should look like to test it specifically - is there something I should be specifically trying?
  • Just confirming - I should have using the “twilio_voice” endpoint, not the “twilio” one.

Did you start the server with rasa run or rasa run --credentials <path-to-credentials.yml>? The former command assumes the credentials.yml exists at the project root.

If you are using Rasa Pro 3.11, you can also run rasa run --inspect and have development inspector for both channels in your credentials.yml
