Today we are happy to announce the launch of Twilio Client, a simple set of developer tools that open up an “audio pipe” from your web or mobile app to Twilio. Using Twilio Client, you can build VoIP applications with just a few lines of code.
Twilio Client costs a fraction of the cost of normal phone calls, just 1/4 cent per minute. For example, a call from one browser to another, anywhere in the world, is just 1/2 penny per minute. In addition to browser based apps, Twilio Client also has a iOS VoIP SDK and Android VoIP SDK for smartphones and tablets.
Creating a Million Skype-Like Experiences for Web & Mobile
Twilio Client offers the simplest, fastest, most intuitive way to build a revolutionary new class of voice-powered applications.
Developers have wanted the ability to create rich communication experiences for years, often inspired by the experience of making and receiving calls with Skype. But developers have needed a fully supported developer platform on which to build.
With the introduction of Twilio Client, millions of web developers can now build VoIP-enabled web, smartphone and tablet applications with an easy API, using their existing development skills, serving their existing customers, using the UI they like best.
Placing an Outbound Call
For example, to place an outbound call originating from the browser, use the following script:
Twilio.Device.connect(); // initiate outbound call
To learn more about making calls and generating the “security token”, check out the Twilio Client Quickstart for making outbound calls.
Receiving an Incoming Call
In addition to placing outbound calls Twilio Client can be configured to handle incoming calls as well. Using the Twilio markup language (TwiML), any call can be routed to any browser registered with the specified client name, like this:
console.log(“Incoming call from ” +
