Cordova plugin for VoIP push notifications



This plugin didn’t exist, so I made it – Cordova plugin for receiving VoIP push notifications on iOS 8.0+ only.


For Ionic:

ionic plugin add cordova-ios-voip-push

For Cordova:

cordova plugin add cordova-ios-voip-push


Please see the Ionic demo for the exact usage example.

Running the demo

Ionic setup

Clone this repo:

git clone

CD into the cloned project and the Ionic demo project:

cd cordova-ios-voip-push && cd ionicDemo

Install the dependencies:

npm install && bower install

Install the platform and plugins (please note that this process may take a while to complete):

ionic state reset

Add the plugin (either one of three options would work):

ionic plugin add cordova-ios-voip-push


ionic plugin add ../thePlugin/VoIPPushNotification

or like this:

ionic plugin add

Prepare the project:

ionic prepare ios

Open the project in XCode by going into platforms/ios and opening up the pluginTest.xcodeproj file.

XCode setup

If you don’t have an AppID and VoIP push certificate created in your Apple developer account, you can do so by following my instructions from the How to create a native iOS app that can receive VoIP push notifications tutorial.

Take your time to do that an then come back, I’ll wait.

To use the VoIP push in the app, you need to turn ON the Background Modes for your app and check few of the checkboxes:

Make sure you select the following options:

  • Audio, Airplay, and Picture in Picture
  • Voice over IP
  • Background fetch
  • Remote notifications

Next, you need to add PushKit framework to your project:

Also (yeah, I know, a lot of setup), you need to make sure that you set the appropriate Bundle Identifier. You should have read about this in the tutorial I linked above.

After you run the project, in the XCode console you should see

and on your device:

You can send VoIP pushes to yourself by editing the simplepush.php file (in the pushSendingScript folder from the Github repo). Just make sure you add your own device id that you’ll see show up on your phone. You have more options to send VoIP push, two of which you can read in the post linked few times above.


This tutorial was inspired by the official phonegap-plugin-push plugin, and the fact that this kind of VoIP support didn’t exist. There were requests for it here, here and here. As well as on freelance sites like here, here – hehe, hope these guys will send some donations to my favorite charity if they end up using this now 😉

Also, I don’t ‘do’ ObjectiveC for a living (but I may change my mind after completing this :)), so I would really appreciate the constructive feedback in making this plugin better, so I look forward to your comments and potential pull requests!

In my previous tutorial I showed how to create a native iOS app with Swift (ObjectiveC code also available) that can receive VoIP push notifications sent with Houston, custom PHP script or through Amazon SNS.

In this tutorial I’m going to present to you the Cordova plugin that does the same thing; it allows hybrid iOS applications to receive the VoIP push notifications.

Building Cordova plugins

I won’t go into the details of Cordova plugin building in this document. If you’re new to building Cordova plugins, you can check out this tutorial and official docs, as they were indispensable in my quest to learn as much as possible about it.


In this file you basically define:

  • for which platform is this plugin (<platform name="ios">)
  • where the source files of your plugin will be (header-file and source-file elements)
  • where is the JavaScript file that will be the bridge from Cordova to native code (js-module tag src property)
  • what will be the plugins name by which you’ll reference it in the Cordova/Ionic code (<clobbers target="VoIPPushNotification" />)


This file, stripped of it’s comments is very short (75 LOC):

This code follows the structure of the phonegap-plugin-push push.js.

Once you call the init method, you get the new VoIPPushNotification object which then exposes the methods for listening to the registration, notification and error events.


Since we’re writing in ObjectiveC, we need to define the functions in the .h file. Here we do few things:

  • import Cordova and PushKit
  • add an instance property VoIPPushCallbackId
  • add an init function declaration


In the implementation file we define our functions. The first one is init, and here we basically register for VoIP push notifications by using PKPushRegistry.

Then, to satisfy that, we implement two functions: didUpdatePushCredentials and didReceiveIncomingPushWithPayload.

The first one is triggered with the device token, which we then send back to the ‘JS world’. We listen for this in our Ionic/Cordova apps and send this information to our backend so that later when we’re going to send the push we know to which device id.

The second one is triggered when we receive the actual VoIP push notification. In this example, we take out the message (@alert) and return it to the ‘JS world’. In my particular case, this can be a message with a certain keyword, so that then I know what to do in my app based on that keyword.

Again, I have to stress here that you may wanna alter this to your liking and process even more data which you receive through the VoIP push notification.


I hope this plugin will come handy to you. Also, I hope that this will give you enough information so that you’ll be dangerous enough to go and fiddle with the code yourself.

As I’ve mentioned before, I would really appreciate the constructive feedback so that we can make this plugin better, so I look forward to your comments and optional pull requests.

Btw, I updated these posts with this solution:

and I have also asked the main maintainer of phonegap-plugin-push plugin if this would make sense to put as a PR on that plugin.

I will update you on the progress of all this, and till then – code on!
