I seem to have a problem with Twilio webhooks. I have a Trail account, and have configured webhooks for incoming calls:1.
The server and ngrok run OK. When I send a SMS, the webhook is triggered and my server gets the expected request. However when I call the number, the webhook is not triggered. The voice says that I have a trail account and that I need to press a key to trigger the webhook, but pressing doesn't help and the call gets dissconnected after 15s. When I added a URL as CALL STATUS CHANGES webhook, it was called correctly when the call ended, so the issue seems to be with key presses on incoming calls. The call log details (and my Flask server) confirm that no requests are being made in the case of incoming calls, but show the SMS webhook triggers as expected.
I'm in quite a pickle, since I have no idea how to debug this further. I have called my twilio number with 3 cellphones, one of them being my Verified Caller ID, but with no luck. Thanks for your help!
