Example HTML/CSS/Javascript for the Twilio Client for PhoneGap example.
See https://github.com/jefflinwood/twilio_client_phonegap for the Plugin git repository
Follow the Twilio Client Plugin for PhoneGap instructions, and then copy the index.html and phoneApp.js files from this example application into your project.
Replace the URL at the bottom of phoneApp.js with the URL endpoint of a web service that uses your Twilio credentials to create a capability token - the URL in the javascript file won't work.
