Open VoIP Alliance Webphone Lib
Makes calling easier by providing a layer of abstraction around SIP.js. To figure out why we made this, read our blog post.
Documentation
Check out the documentation here.
Cool stuff
- Allows you to switch audio devices mid-call.
- Automatically recovers calls on connectivity loss.
- Offers an easy-to-use modern javascript api.

Getting started
$ git clone [email protected]:open-voip-alliance/WebphoneLib.git
$ cd WebphoneLib
$ touch demo/config.mjsAdd the following to demo/config.mjs
export const authorizationUserId = <your-voip-account-id>;
export const password = '<your-voip-password>';
export const realm = '<realm>';
export const websocketUrl = '<websocketUrl>';Run the demo-server:
$ npm i && npm run demoAnd then play around at http://localhost:1235/demo/.
Examples
Connecting and registering
import { Client } from 'webphone-lib';
const account = {
user: 'accountId',
password: 'password',
uri: 'sip:accountId@<realm>',
name: 'test'
};
const transport = {
wsServers: '<websocket-url>', // or replace with your
iceServers: [] // depending on if your provider needs STUN/TURN.
};
const media = {
input: {
id: undefined, // default audio device
audioProcessing: true,
volume: 1.0,
muted: false
},
output: {
id: undefined, // default audio device
volume: 1.0,
muted: false
}
};
const client = new Client({ account, transport, media });
await client.register();Incoming call
// incoming call below
client.on('invite', (session) => {
try {
ringer();
let { accepted, rejectCause } = await session.accepted(); // wait until the call is picked up
if (!accepted) {
return;
}
showCallScreen();
await session.terminated();
} catch (e) {
showErrorMessage(e)
} finally {
closeCallScreen();
}
});Outgoing call
const session = client.invite('sip:518@<realm>');
try {
showOutgoingCallInProgress();
let { accepted, rejectCause } = await session.accepted(); // wait until the call is picked up
if (!accepted) {
showRejectedScreen();
return;
}
showCallScreen();
await session.terminated();
} catch (e) {
} finally {
closeCallScreen();
}Attended transfer of a call
if (await sessionA.accepted()) {
await sessionA.hold();
const sessionB = client.invite('sip:519@<realm>');
if (await sessionB.accepted()) {
// immediately transfer after the other party picked up :p
await client.attendedTransfer(sessionA, sessionB);
await sessionB.terminated();
}
}Audio device selection
Set a primary input & output device:
const client = new Client({
account,
transport,
media: {
input: {
id: undefined, // default input device
audioProcessing: true,
volume: 1.0,
muted: false
},
output: {
id: undefined, // default output device
volume: 1.0,
muted: false
}
}
});Change the primary I/O devices:
client.defaultMedia.output.id = '230988012091820398213';Change the media of a session:
const session = await client.invite('123');
session.media.input.volume = 50;
session.media.input.audioProcessing = false;
session.media.input.muted = true;
session.media.output.muted = false;
session.media.setInput({
id: '120398120398123',
audioProcessing: true,
volume: 0.5,
muted: true
});Commands

Generate documentation
Typedoc is used to generate the
documentation from the jsdoc comments in the source code. See this
link for more information on which
jsdoc tags are supported.
Run puppeteer tests
Using docker
Add a .env file with the following:
USER_A = <user-a>
USER_B = <user-b>
PASSWORD_A = <password-user-a>
PASSWORD_B = <password-user-b>
NUMBER_A = <number-user-a>
NUMBER_B = <number-user-b>
WEBSOCKET_URL = <your-websocket-url>
REALM = <realm>
Then call docker-compose up to run the tests.
Note: Don't forget to call npm ci in the puppeteer folder. :)
Without docker
If you don't want to use docker, you will need to run the demo with the npm run demo command (and keep it running) and run the tests with npm run test:e2e. For this you will need the .env file with your settings.
