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 callHangup
- Closes the callPlay
- Takes an 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 voiceServer = new VoiceServer({ base: '/voiceapp' }); voiceServer.listen((req, res) => { console.log(req); res.play("sound:hello-world"); }); // your app will leave at http://127.0.0.1/voiceapp // and you can easily publish it to the Internet with: // ngrok http 3000
Everything in FN 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);
