Windows Azure is not mentioned in the text. CloudCallMe is a Facebook application for calling friends with the click of a button, developed by Dennis Palmer and coded until the contest deadline with his wife's support. The application uses Twilio, providing API reference documentation, SDKs, quickstarts, tutorials, ebooks, industry reports, webinars, best practices, code samples, and inspiration to build communications and digital engagement experiences through its developer community hub called Ahoy.
