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 callHangup- Closes the callPlay- Takes a URL or file and streams the sound back to the calling partySay- Takes a text, synthesizes the text into audio, and streams back the resultGather- Waits for DTMF or speech events and returns back the resultSGather- Returns a stream for future DTMF and speech resultsDial- Passes the call to an Agent or a Number at the PSTNRecord- It records the voice of the calling party and saves the audio on the Storage sub-systemMute- It tells the channel to stop sending media, effectively muting the channelUnmute- 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 3000Everything 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"
})
