twilio java connection with proxy authentication

Question

I am setting up a java Twilio connection using the example Twilio java-sdk from the api examples here.

The only difference is I need to run my Twilio connection through

Answer 1

Resolved... just needed to add another set of credentials that were scoped to api.twilio.com after the proxy credentials:

    //Set up Proxy user credentials
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            new AuthScope(PROXY_ADDRESS, PROXY_PORT), 
            new UsernamePasswordCredentials(PROXY_USER, PROXY_PASSWORD));

    //Set up Twilio user credentials
    credsProvider.setCredentials(
            new AuthScope("api.twilio.com", 443), 
            new UsernamePasswordCredentials(ACCOUNT_SID, AUTH_TOKEN));

I'll leave this here for posterity because there has been several questions about this but no accepted answers.
