Twilio autopilot handoff action is not working with Twiml Bin

I have a Twilio autopilot task from an incoming call, which performs a greeting then asks a question before redirecting to a new task called 'callnumber'. This all works fine.

The 'callnumber' task looks like this

{
    "actions": [
        {
            "handoff": {
                "channel": "voice",
                "uri": "https://handler.twilio.com/twiml/TWIMLBINID"
            }
        }
    ]
}

TWIMLBINID actually has the correct ID from the Twiml Bin.

This is the Twiml content in the bin:

<Response>
    <Say>I will put you in contact with our customer care specialist.</Say>
</Response>

Unfortunately I'm not hearing this Response spoken out and instead just get the standard 'an error has occurred' voice message.

I've tried a few different versions of this, even calling an xml file hosted on my own public web server and seeing the same problem. Also tried the dial verb and still seeing this issue.

I feel like I may have missed some configuration, after seeing similar posts like: Twilio autopilot doesnt say what it is supposed to say

Any help is much appreciated!

Solution

  • I was able to get the TwiML Bin working with similar JSON, when I have it associated with a Task that has samples.

    So, for example, a call comes in to your Autopilot assistant and initially triggers the Assistant Initiation Task of hello_world where you modified the predefined JSON with a listen action. 

    {
    "actions": [
        {
            "say": "How can I help you today?"
        },
        {
            "listen": true
        }
    ]
}

    You then respond so the task associated with your handoff JSON/TwiML Bin is executed (based on the samples you provided). If you try to call the handoff task directly, it fails.
