Device Undefined

[rochapablo]

Following the example, I'm getting:

_deviceReady params undefined
_deviceDidStartListening params undefined

{ type: 'DEVICE_LISTENING_START', params: undefined }
{ callState:
   {
      callDirection: null,
      callingError: 'Twilio Services Error',
      callFromNumber: null,
      callToNumber: null,
      listening: true
   },
   telephonyState: { deviceReady: true, deviceError: null, clientName: 'jenny' }
}

And this is what I'm trying to

Twilio.init()
Twilio.makeCall(`client:Julia-1`)

const telephonyService = {
  init (client) {
    this.initDeviceListeners()
    return new Promise((resolve, reject) => {
      api.request().then((token) => {
        Twilio.initWithToken(token)
        return resolve(true)
      }).catch((error) => {
        return resolve(error)
      })
    })
  },
