+Your app must initialize PKPushRegistry with PushKit push type VoIP at the launch time. As mentioned in the
+[PushKit guidelines](https://developer.apple.com/documentation/pushkit/supporting_pushkit_notifications_in_your_app), 
+the system can't deliver push notifications to your app until you create a PKPushRegistry object for VoIP push type and set the delegate. If your app delays the initialization of PKPushRegistry, your app may receive outdated
+PushKit push notifications, and if your app decides not to report the received outdated push notifications to CallKit, iOS may terminate your app.
+
+We will initialize push kit only if RN code had called TwilioVoice.initWithAccessToken(token) and we've cached device token. You can pass same arguments to initPushKitIfTokenCached as you would pass to configureCallKit

 #### VoIP Service Certificate
 
 Twilio Programmable Voice for iOS utilizes Apple's VoIP Services and VoIP "Push Notifications" instead of FCM. You will need a VoIP Service Certificate from Apple to receive calls. Follow [the official Twilio instructions](https://github.com/twilio/voice-quickstart-ios#7-create-voip-service-certificate) to complete this step.
