**EDIT : ** here is connect() method called when Call Button is clicked :

public void connect(String fromMobileNo, String phoneNumber)
    {

        Map<String, String> parameters = new HashMap<String, String>();

        parameters.put("frommobileno", fromMobileNo);
        parameters.put("mobileno",  phoneNumber);

        Log.d("parameters", parameters + "");
        Log.d(TAG, "device :" + device);
        Log.d(TAG, "device :" + device);

        if(device == null)
        {
            Toast.makeText(getApplicationContext(),"Sorry from our side.Please try again.",Toast.LENGTH_LONG).show();
            finish();
        }
        else{
            connection = device.connect(parameters, (Controller)getApplication()/* ConnectionListener */);

            if (connection == null && ((Controller)getApplication()).basicConnectionListener != null)
                ((Controller)getApplication()).basicConnectionListener.onConnectionFailedConnecting(new Exception("Couldn't create new connection"));

        }

        if (connection != null){
            Controller.setConnection(connection);


        }else {
            Log.w(TAG, "Failed to create new connection");
        }

    }

Answer 1

C# Users

Setup your TWILIO credentials as environment variables.

Check here : Add environment variables Windows

Call them as follow :

    string accountSid = Environment.GetEnvironmentVariable("TWILIO_ACCOUNT_SID");
    string authToken = Environment.GetEnvironmentVariable("TWILIO_AUTH_TOKEN");

Then execute the program.

Answer 2

you have to use this twilio console for your account sid and auth token instead of this!

[Edit]: The second link is the old twilio user panel which I think is being redirected to the new one from exactly the date that I am editing this answer(!) which is the first link in above. retrying getting new account sid and the auth token again using the new user panel control(www.twilio.com/console) solved the problem for me.

Answer 3

Capability token has a life time. Its gets expired after it. I think, this issue is with expiration of your capability token.

So update your capability token to solve this issue.

Follow below steps to overcome this problem

Step 1 : First try to check the state of your device before making out calls.

Check device state

Step 2 : If your device is OFFLINE, try to update token. If READY, call. If BUSY, dont call.

Device State Values
