Twilio DTMF echo problem

Set in configuration fakeLocalDTMF:true 

Update sound object in configuration file for the fake DTMF

Here’s how to set it straight through device interface, not through configuration file:

Twilio.Device.setup(token, {
  sounds: {
    incoming: 'http://mysite.com/incoming.mp3',
    outgoing: 'http://mysite.com/outgoing.mp3',
    dtmf8: 'http://mysite.com/funny_noise.mp3'
  }
}

Dtmf could also be silent.
