Attention ⚠️:

Exploring Fonoster: We encourage new users to initially explore Fonoster's features through our SaaS (Software as a Service) option. This platform is free to start and offers a comprehensive experience of what Fonoster can do.

Installation Advisory: Please note that the current installation process for Fonoster is complex. We are actively working to simplify this process. We recommend waiting for our upcoming 0.4 or 0.5 release before attempting a direct installation. These future releases are designed to offer a more user-friendly installation experience.

Thank you for your interest in Fonoster. We are committed to enhancing your experience with every release.

Code Examples

A Voice Application is a server that takes control of the flow in a call. A Voice Application can use any combination of the following verbs:

  • Answer - Accepts an incoming call
  • Hangup - Closes the call
  • Play - Takes an URL or file and streams the sound back to the calling party
  • Say - Takes a text, synthesizes the text into audio, and streams back the result
  • Gather - Waits for DTMF or speech events and returns back the result
  • SGather - Returns a stream for future DTMF and speech results
  • Dial - Passes the call to an Agent or a Number at the PSTN
  • Record - It records the voice of the calling party and saves the audio on the Storage sub-system
  • Mute - It tells the channel to stop sending media, effectively muting the channel
  • Unmute - It tells the channel to allow media flow

Voice Application Example:

const { VoiceServer } = require("@fonoster/voice");

const serverConfig = {
  pathToFiles: `${process.cwd()}/sounds`,
};

new VoiceServer(serverConfig).listen(
  async (req, res) => {
    console.log(req);
    await res.answer();
    await res.play(`sound:${req.selfEndpoint}/sounds/hello-world.sln16`);
    await res.hangup();
  }
);

// your app will live at http://127.0.0.1:3000 
// and you can easily publish it to the Internet with:
// ngrok http 3000

Everything in Fonoster is an API first, and initiating a call is no exception. You can use the SDK to start a call with a few lines of code.

Example of originating a call with the SDK:

const Fonoster = require("@fonoster/sdk");
const callManager = new Fonoster.CallManager();

callManager.call({
 from: "9842753574",
 to: "17853178070",
 webhook: "https://5a2d2ea5d84d.ngrok.io/voiceapp"
})
 .then(console.log)
 .catch(console.error);
