capacitor-callkit-voip

Provide PushKit functionality to ionic capacitor

This plugin has been written for BetterCall app.

Install

  1. Install plugin
npm install @capgo/capacitor-callkit-voip
ionic cap sync
  1. Xcode Project > Capabilities pane. Select the checkbox for Voice over IP, as shown in Image

npm.io

  1. Register certificate on developer.apple.com/certificates

npm.io

  1. Download the certificate and open it to import it into the Keychain Access app.

  2. Export certificates as shown bellow

npm.io

  1. Now, navigate to the folder where you exported this file and execute following command:
openssl pkcs12 -in YOUR_CERTIFICATES.p12 -out app.pem -nodes -clcerts
  1. You will receive app.pem certificate file that can be used to send VOIP notification (you can use my script bellow)

Usage

To make this plugin work, you need to call .register() method and then you can use API bellow.

import {CallKitVoip} from "@capgo/capacitor-callkit-voip"


async function registerVoipNotification(){
    // register token 
    CallKitVoip.addListener("registration", (({token}:Token) =>
      console.log(`VOIP token has been received ${token}`)
    ))
  
    // start call
    CallKitVoip.addListener("callAnswered", (({username, connectionId}:CallData) => 
      console.log(`Call has been received from ${username} (connectionId: ${connectionId})`)
    ));
    
    // init plugin, start registration of VOIP notifications 
    await CallKitVoip.register(); // can be used with `.then()`
    console.log("Push notification has been registered")
  
}

Once the plugin is installed, the only thing that you need to do is to push a VOIP notification with the following data payload structure:

{
    "Username"      : "Display Name",
    "ConnectionId"  : "Unique Call ID"
}

You can use my script (bellow) to test it out: ./sendVoip.sh <connectionId> <deviceToken> <username>

sendVoip.sh:

#!/bin/bash

function main {
    connectionId=${1:?"connectionId should be specified"}
    token=${2:?"Enter device token that you received on register listener"}
    username=${3:-Anonymus"}

    curl -v \
    -d "{\"aps\":{\"alert\":\"Incoming call\", \"content-available\":\"1\"}, \"Username\": \"${username}\", \"ConnectionId\": \"${connectionId}\"}" \
    -H "apns-topic: <YOUR_BUNDLE_ID>.voip" \
    -H "apns-push-type: voip" \
    -H "apns-priority: 10" \
    --http2 \
    --cert app.pem \
"https://api.development.push.apple.com/3/device/${token}"
}

main $@

Pay attention:

  • replace <YOUR_BUNDLE_ID> with your app bundle
  • ensure that you are using correct voip certificate (specified in --cert app.pem)
  • if you'll go to production version, you will need to do request to api.push.apple.com/3/device/${token} instead of api.development.push.apple.com/3/device/${token}, otherwise you will receive BadDeviceToken issue

API

register()

Register your device to receive VOIP push notifications. After registration it will call 'registration' listener (bellow) that returns VOIP token.

import {CallKitVoip} from "@capgo/capacitor-callkit-voip"
//...
await CallKitVoip.register();
// or
CallKitVoip.register().then(() => {
    // Do something after registration
});

Returns: void


addListener("registration", handler)

Adds listener on registration. When device will be registered to receiving VOIP push notifications, listenerFunc will be called.

As usually, it's called after .register() function

import {CallKitVoip, Token} from "@capgo/capacitor-callkit-voip"
//...
CallKitVoip.addListener("registration", (({token}:Token) => {
    // do something with token 
    console.log(`VOIP token has been received ${token}`)
}));
ParamType
eventName"registration"
listenerFunc(token: Token) => void

Returns: any


addListener("callAnswered", handler)

Adds listener to handle when user answers on call.

import {CallKitVoip, Token} from "@capgo/capacitor-callkit-voip"
//...
CallKitVoip.addListener("callAnswered", (({username, connectionId}:CallData) => {
    // handle call (e.g. redirect it to specific page with call)
    console.log(`Call has been received from ${username} (connectionId: ${connectionId})`)
}));
ParamType
eventName"callAnswered"
listenerFunc(callDate: CallData) => void

Returns: void


addListener("callStarted", handler)

Adds listener to handle call starting. I am not sure if it's usable, because you can handle it directly in your app

import {CallKitVoip, Token} from "@capgo/capacitor-callkit-voip"
//...
CallKitVoip.addListener("callStarted", (({username, connectionId}:CallData) => {
    // handle call (e.g. redirect it to specific page with call)
    console.log(`Call has been started with ${username} (connectionId: ${connectionId})`)
}));
ParamType
eventName"callStarted"
listenerFunc(callDate: CallData) => void

Returns: any
