Introduction
I made a VOIP dialer app with react-native. I'm using react-native-callkeep to show the user the default IOS call screen when receiving a call (On background and foreground), and i'm using react-native-push-notification to pop-up a local notification when a call is received too.
The problem
When i minimize the app (With the home button) and the app receives a call, he doesn't show neither the local notification or the call screen.but, if the call comes right after the minimize action, the screen and the notification shows up.
Tecnical explanation of what happens
Reading the logs, i see that IOS kills my app background processing when he prints the following line:
15:08:23.085311-0300 symptomsd com.vmaxtelecom.vmaxfone: Foreground: false
After this, nothing works on foreground neither background
Code explanation
Probably, the problem isn't with react-native-callkeep or with react-native-push-notification itself (Because they're work as intended). I think it's something with IOS Itself.
I found this thread wich defines exactly what happens to me.
My enabled capabilities
What i'm using
react-native version 0.61.5
Xcode version 11.5 (11E608c) on a MacOS 10.15.5 Catalina
IOS 13.4.1 on a Iphone 8
I'm using a release version of my project (The debug version does the same thing too)
My AppDelegate.m (Only the part after didFinishLaunchingWithOptions matters the most)

function initCallKitIntegration() { return async function (dispatch, getState) { let activeCall = null const uuids = {} const options = { ios: { appName: 'VMAX Fone', imageName: 'phone_account_icon', includesCallsInRecents: true, supportsVideo: false } } RNCallKeep.setup(options).then(accepted => {}) let incomingCall = null const {endpoint} = getState().pjsip const {appState} = getState().pjsip endpoint.on("call_received", (call) => { RNCallKeep.addEventListener('answerCall', () => { //accept call here }) RNCallKeep.addEventListener('endCall', () => { //decline call here }) RNCallKeep.addEventListener('didPerformDTMFAction', ({ digits, callUUID }) => { //send dtmf digits here }) RNCallKeep.addEventListener('didPerformSetMutedCallAction', ({ muted, callUUID }) => { //mute and unmute call here }) RNCallKeep.addEventListener('didToggleHoldCallAction', ({ hold, callUUID }) => { //hold and unhold call here }) endpoint.on("call_changed", (call) => { //Change Call state here }) endpoint.on("call_terminated", (call) => { //endCall here RNCallKeep.endCall(uuids[call.getCallId()]) delete uuids[call.getCallId()] }) if (appState != 'active'){ RNCallKeep.displayIncomingCall(uuids[call.getCallId()], call.getRemoteNumber(), call.getRemoteNumber(), 'number', false) } }) }}The logs
