React Native CallKeep

React Native CallKeep shows your app's VoIP calls in the phone's own call UI: CallKit on iOS and ConnectionService (Telecom) on Android. Incoming calls ring on the lock screen, calls appear in the system's recents, and the user answers, holds, mutes or hangs up from the system UI.

   

CallKeep handles the call UI and the system integration. The audio and the signaling come from your VoIP stack, for example react-native-webrtc or a SIP library.

Compatibility

React Native	Tested with 0.87, New Architecture enabled
iOS	React Native's minimum (15.1 with 0.87). Calls need a device: the Simulator has no CallKit service. Tested on iOS 26 and 27
Android	Android 6 (API 23) and later; self-managed mode needs Android 8 (API 26). Calls work on emulators. Tested on Android 10 and 16
Expo	With a development build, not Expo Go: see the Expo guide

Installation

npm install react-native-callkeep
cd ios && pod install

Then follow the platform setup: iOS and Android.

Quick start

import RNCallKeep from 'react-native-callkeep';

await RNCallKeep.setup({
  ios: { appName: 'My App' },
  android: {
    // Shown when the user has to enable the app's phone account.
    alertTitle: 'Permissions required',
    alertDescription: 'This application needs to access your phone accounts',
    cancelButton: 'Cancel',
    okButton: 'OK',
    additionalPermissions: [],
  },
});

// The user answered, from the system call UI or your app.
RNCallKeep.addEventListener('answerCall', ({ callUUID }) => {
  // Connect the call's media, then tell Android the call is active.
  RNCallKeep.setCurrentCallActive(callUUID);
});

// The call ended, from the system call UI or your app.
RNCallKeep.addEventListener('endCall', ({ callUUID }) => {
  // Hang up the call's media.
});

// An incoming call, typically when your server tells the app about one.
// callUUID is a UUID v4 that identifies the call, for example from the `uuid` package.
RNCallKeep.displayIncomingCall(callUUID, '5551234', 'Alice');

The example app shows every part of the library with simulated calls, on iOS and Android, and explains which file to look at for each part.
