RingCentral Call Control JS SDK

Coverage Status NPM Version Build Status

RingCentral Call Control JS SDK is wrapper of RingCentral JS SDK to help developers call RingCentral Call Control API more functionally.

Features:

We added the following key features to do the heavy lifting for you.

  • Call session management to load existing call sessions or create call session.
  • Call session event. Handle telephony session notifications, manage call session lifecycle
  • Call session management with functional API.
  • Devices management to load user’s devices.

Notice: This library doesn't provide ability of voice transmission. For working with WebRTC voice transimission, please use RingCentral Call JS SDK. It combines WebRTC voice transimission and Call Control RESTful APIs.

Prerequisites

  • You will need an active RingCentral account to create RingCentral app. Don't have an account? Get your Free RingCentral Developer Account Now!
  • A RingCentral app
    • App type: Browser-Based or Server/Web
    • Permissions: 'Call Control', 'Read Accounts', 'Read Presence', 'Webhook Subscriptions'

Usage

For this example you will also need to have RingCentral JS SDK and RingCentral JS Subscriptions SDK installed.

Configure and new Call Control instance:

// npm import
// import { RingCentralCallControl } from 'ringcentral-call-control';
// or use CDN
// window.RingCentralCallControl

var appClientId = '...'; 
var appClientSecret = '...';
var appName = '...';
var appVersion = '...';

var sdk = new RingCentral.SDK({
  clientId: appClientId,
  clientSecret: appClientSecret,
  appName: appName,
  appVersion: appVersion,
  server: RingCentral.SDK.server.production // or .sandbox
});
var subscriptions = new RingCentral.Subscriptions({
  sdk: sdk
});
var platform = sdk.platform();

platform
  .login({
    username: '...',
    password: '...'
  })
  .then(function() {
    var rcCallControl = new RingCentralCallControl({ sdk: sdk });
    var subscription = subscriptions.createSubscription();

    subscription.setEventFilters(['/restapi/v1.0/account/~/extension/~/telephony/sessions']);
    subscription.on(subscription.events.notification, function(msg) {
       rcCallControl.onNotificationEvent(msg)
    });
    subscription.register();
    return rcCallControl;
  })

Demo

$ git clone https://github.com/ringcentral/ringcentral-call-control-js.git
$ cd ringcentral-call-control-js
$ yarn
$ yarn build
$ yarn start

Open http://localhost:8080/demo/, and login with RingCentral Sandbox account to test.

API

Init

Firstly, we need to create Call Control instance after user login with RingCentral JS SDK. Then connect onNotificationEvent with subscription notification event.

var rcCallControl = new RingCentralCallControl({ sdk: sdk });
var initialized = false;
var subscription = subscriptions.createSubscription();
subscription.setEventFilters(['/restapi/v1.0/account/~/extension/~/telephony/sessions']);
subscription.on(subscription.events.notification, function(msg) {
  rcCallControl.onNotificationEvent(msg)
});
subscription.register();
rcCallControl.on('initialized', function() {
  initialized = true;
});

Events

New session event

var session = null;

rcCallControl.on('new', (newSession) => {
  session = newSession;
});

Initialized

rcCallControl.on('initialized', function() {
  initialized = true;
});

Sessions List

var sessions = rcCallControl.sessions;

Session API

Create a Call Session

var session = null;
var deviceId = rcCallControl.devices.filter(d => d.status === 'Online')[0].id;
rcCallControl.createCall(deviceId, { phoneNumber: 'phoneNumberToCall' }).then((newSession) => {
  session = newSession;
  // ...
})

Drop Session

Drops a call session.

session.drop().then(...);

Hold Unhold

Puts the party to stand-alone mode and starts to play Hold Music according to configuration & state to peers. There is a known limitation for Hold API - hold via REST API doesn't work with hold placed via RingCentral apps or HardPhone. It means that if you muted participant via Call Control API and RingCentral Desktop app, then you need to unhold both endpoints to remove Hold Music and bring media back.

session.hold().then(...);
session.unhold().then(...);

Mute Unmute

Callee will be put on mute or unmute

session.mute().then(...);
session.unmute().then(...);

To Voicemail

session.toVoicemail().then(...);

Ignore in call queue

session.ignore({ deviceId: 'your_device_id' }).then(...);

Answer

session.answer({ deviceId: 'your_device_id' }).then(...);

Reply with message

session.reply({ replyWithText: 'On my way' }).then(...);
session.reply({
  replyWithPattern: {
    pattern: 'WillCallYouBack',
    time: 10,
    timeUnit: 'Minute'
  }
}).then(...);

Forward

Distributes a non-answered call to the defined target. Applicable for "Setup" or "Proceeding" states

session.forward({ phoneNumber: 'phoneNumber' }).then(...);

Transfer

Transfers a party by placing a new call to the specified target

session.transfer({ phoneNumber: 'phoneNumber' }).then(...);

Flip

Performs call flip procedure by holding opposite party and calling to the specified target.

session.flip({ callFlipId: 'callFlipId' }).then(...);

Park

Performs call park procedure to set on park one of the call parties in call dialog.

session.park().then(...);

Recording

Starts a new call recording for the party

session.createRecord().then(...);

Pause/resume recording

session.pauseRecord('recordingId').then(...);
session.resumeRecord('recordingId').then(...);

Supervise

Allows to monitor a call in 'Listen' mode. Input parameters should contain extension number of a monitored user and internal identifier of a supervisor's device. Call session should be specified in path. Currently is not supported for Sandbox environment.

session.supervise({
  mode: 'Listen',
  deviceId: 'your deviceId',
  extensionNumber: 'extensionNumber'
}).then(...);

Session Events

Status

session.on('status', (event) => {
  // on status changed
  var party = event.party;
  var status = party.status;
  // ...
});

Muted

session.on('muted', () => {
  // on muted changed
  var muted = session.muted;
  // ...
});

Devices

Get current extension's all devices:

var devices = rcCallControl.devices;

Refresh devices:

rcCallControl.refreshDevices().then(() => {
  var devices = rcCallControl.devices;
});
