Error: callerId must be provided for TwilioClient and SIP calls when using Dial (after VoiceResponse TwiML steps)

Description

callerId must be provided for TwilioClient and SIP calls when using Dial. This error is notified to the the action callback (parameter) of the TwiML VoiceResponse instance, before sdk finally shows a 403 (forbidden).

Steps to Reproduce

iOS SDK starts the call
The TwiML post action is called, linked to a serverless function.
The function returns correctly the TwiML steps.
However error is notified to the action URI on my server with the following (form) properties:
=> DialCallStatus: failed, ErrorMessage: callerId must be provided for TwilioClient and SIP calls when using Dial
On client (sdk) end, this is is logged as a SIP/2.0 403 Forbidden (not relevant).

Code

Serverless / TwiML steps creation

If you are from Twilio team, the endpoint (protected) is: https://wheat-bat-8252.twil.io/live

Code of the function:

exports.handler = async (context, event, callback) => {
  // set-up the variables that this Function will use to forward a phone call using TwiML

  // generate the TwiML to tell Twilio how to forward this call
  let voiceResponse = new Twilio.twiml.VoiceResponse();

    ......

    const { callId, numberFrom } = response.data;

    let dialParams = {};
    dialParams.callerId = numberFrom
    dialParams.answerOnBridge = true
    dialParams.method = 'POST'
    dialParams.action = 'myserver'
    dialParams.recordingStatusCallback = 'myserver'
    dialParams.record = 'record-from-answer-dual'
    dialParams.recordingStatusCallbackEvent = 'in-progress completed absent'
    dialParams.timeout = 23

    const dialObj = voiceResponse.dial(dialParams);
    dialObj.number(numberTo);

    // return the TwiML
    callback(null, voiceResponse);

Generated TwiML (voiceResponse value at the end):

VoiceResponse: 

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial callerId="+34mynumber" answerOnBridge="true" method="POST" action="myserver" recordingStatusCallback="myserver" record="record-from-answer-dual" recordingStatusCallbackEvent="in-progress completed absent" timeout="23">
        <Number>+34destnumber</Number>
    </Dial>
</Response>

The weird thing is that the TwiML response looks correct. And yes, I can guarantee it has nothing to do with the + character. Happens with or without it.

Expected Behavior

Call starts and following callbacks/actions occurr.

Actual Behavior

Call does not start because of the callerId error, which has been notified to the action endpoint (myserver).
