I am using Twilio api for developing a video calling web app. Web app is responsive and can be used on mobile device to make video calls. But when I open my web page on mobile device browser it is not using loudspeaker by default. As per Twilio API Doc we can use Twilio.Device object to set loudspeaker as default. I am stucked on below code, where it is throwing exception followed by the code.

Twilio.Device.setup(token)

Uncaught TypeError: Cannot read property 'length' of undefined

This help page did it for me: https://www.twilio.com/docs/tutorials/browser-calls-csharp-mvc#make-a-dashboard-for-our-support-agents

Where I was using Claims before, it was scopes that got it working

var scopes = new HashSet<IScope>
{
    new IncomingClientScope(identity),
    new OutgoingClientScope(appSid)
};
var capability = new Twilio.Jwt.ClientCapability(accountSid, authToken, scopes: scopes);
var token = capability.ToJwt();

I was using this before, capability.Claims.Add("allow_client_outgoing", appSid); capability.Claims.Add("allow_client_incoming", identity);

My code is for allowing incoming and outgoing voice calls. But its likely similar for your video calls.
