Use common languages like Javascript, PHP and Ruby to build killer telephone apps. Or just build some telephone functionality into your existing web site.

The iCall Open Voice API allows you to send and receive SMS messages, build automated call trees, create survey's, route calls and so much more!

iCall's Open Voice API is all about freedom. Freedom to use as little or as much of our API as you want, freedom to use the programming language of your choice, and freedom to use Open Voice XML, REST or Twillio compatibility mode as your telco language.

Unlike competitors, iCall is a telecom provider first, and on top of our mature and reliable telco infrastructure we provide you with these great tools. You wouldn't take financial advice from a guy on the subway, so why would you build your telco infrastructure on top of anything but a phone company?
