I have been having a problem in our application while handling the VoIP notifications. sometimes the didReceiveIncomingPushWith delegate function is invoked when a VoIP Notif is sent but when the call is accepted nothing happened from the caller's side, like the callback to the caller to notify him that the call is accepted doesn't happe. And sometimes the didReceiveIncomingPushWith is not even invoked when a VoIP notif is sent. here is a potion of the code. func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) { NSLog("pushRegistry didReceiveIncomingPushWith() type:(type)") // Handle the push payload if let pushHashtable = payload.dictionaryPayload["aps"] as? [AnyHashable: Any] { if let pushMessage = pushHashtable["alert"] as? String { NSLog("push message=\(pushMessage)") } } if type == PKPushType.voIP { // Process the received push: if it is a VoIP push, this must be an incoming call because we deactivated push for REGISTER refresh from Kamailio server if SipService.instance?.currentCall != nil { // A call is already going on, ignore this VoIP push NSLog("pushRegistry - voip push, and we already have a currentCall: we already received the INVITE, or it is a voip push for another call -> let's ignore it") completion() return } // We want to send a REGISTER anyway to get the pending INVITE message. // Then, the incoming call will be notified in the SIP stack onCallNew(_ call: Call!) callback // Since iOS 13, it is mandatory to report an incoming call immediately after a Voip push // instead of waiting for the SIP INVITE (in EngineDelegate.onCallNew()) // See details here: https://forums.developer.apple.com/message/376630#376630 NSLog("pushRegistry - >= iOS 13 -> showing callkit before SIP INVITE") if let callerSipUri = payload.dictionaryPayload["caller-sip-uri"] as? String { NSLog("push caller-sip-uri=\(String(describing: callerSipUri))") SipUtils.findCallerName(fromSip: callerSipUri) { callerName in let customCallerName = (callerName ?? "Inconnu") + (CallKitService.instance?.CALLKIT_DEBUG_MODE == true ? " [PUSH]" : "") DispatchQueue.main.async { CallKitService.instance?.reportNewIncomingCallToCallKit(callerName: customCallerName) { completion() } } } } else { // That should not happen: Kamailio server is supposed to add the caller SIP URI in the VoIP push DispatchQueue.main.async { CallKitService.instance?.reportNewIncomingCallToCallKit(callerName: nil) { completion() } } } // No call is going on, so we want to take this call, so we want to send a REGISTER if needed SipNetworkMonitoring.instance.start() } else { NSLog("pushRegistry - not a VoIP push") completion() } } here is the reportNewIncomingCallToCallKit function implementation func reportNewIncomingCallToCallKit(callerName: String?, completion: @escaping () -> Void) { NSLog("Callkit - reportNewIncomingCallToCallKit from %@", callerName ?? "Inconnu") let update = CXCallUpdate() update.remoteHandle = CXHandle(type: .generic, value: callerName ?? "Inconnu") update.hasVideo = true // we may already have reported a new call to CallKit // (since iOS13, we must do it in the didReceiveIncomingPushWith() callback) // In this case, the CallKit UI is already showing with caller="Inconnu": we will update it with the caller name. if let currentUuid = currentUuid { NSLog("Callkit - already a CallKit call showing -> updating the existing call ...") self.cxProvider?.reportCall(with: currentUuid, updated: update) } else { NSLog("Callkit - now CallKit call showing -> new call ...") let newUuid = UUID() self.currentUuid = newUuid self.cxProvider?.reportNewIncomingCall(with: newUuid, update: update) { error in completion() } } // dont configure audioSession here, wait for the Callkit "didActivate audioSession" callback } just to clarify : findCallerName is a function to get the called name from a list from the Backend with an escaping closure, (I tried to overpass that function and just give a default name to the caller but still same problem) . ANY HELP PLEASE?

The push is received normally, but the metrics are displayed as 0, making it impossible to check any indicators. Someone knows any solution? The metrics implemented in Braze using the same method are displayed normally, but the implementation through FCM is only shown as 0.

I'm trying to integrate Callkit into a Flutter app that uses webRTC for calls and I have an issue with taking calls on locked screen. CXAnswerCallAction requires to have the action.fulfill() method called after the connection is established. Here is a pice of code without waiting for establishment of the connection: guard let call = self.callManager?.callWithUUID(uuid: action.callUUID) else{ action.fail() return } call.data.isAccepted = true self.answerCall = call self.callManager?.updateCall(call) sendEvent(SwiftCallKeepPlugin.ACTION_CALL_ACCEPT, call.data.toJSON()) DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1200)) { self.configureAudioSession() } action.fulfill() } This causes the connection time counter to be immediately visible on the screen, but the user still has to wait for connection establishment and can't hear anything. Here is the code that waits for the establishment of the connection before calling action.fulfill(): if(self.awaitedConnection.uuid != uuid) { action.fail() } else if(self.awaitedConnection.isConnected) { DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1200)) { self.configureAudioSession() } action.fulfill() } else { DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1000)) { self.waitForConnection(uuid: uuid, action: action) } } } public func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) { guard let call = self.callManager?.callWithUUID(uuid: action.callUUID) else{ action.fail() return } call.data.isAccepted = true self.answerCall = call self.callManager?.updateCall(call) self.awaitedConnection.uuid = action.callUUID self.awaitedConnection.isConnected = false sendEvent(wiftCallKeepPlugin.ACTION_CALL_ACCEPT, call.data.toJSON()) waitForConnection(uuid: action.callUUID, action: action) } Unfortunately, though it works great on iOS 15.7, on 17.3 it causes lack of audio, no sound and no recording. I also can't enable it later when the call is ongoing. For reference: let session = AVAudioSession.sharedInstance() do{ try session.setCategory(AVAudioSession.Category.playAndRecord, options: AVAudioSession.CategoryOptions.allowBluetooth) try session.setMode(self.getAudioSessionMode(data?.audioSessionMode ?? "voiceChat")) try session.setActive(data?.audioSessionActive ?? true) try session.setPreferredSampleRate(data?.audioSessionPreferredSampleRate ?? 44100.0) try session.setPreferredIOBufferDuration(data?.audioSessionPreferredIOBufferDuration ?? 0.005) }catch{ print(error) } } I can see in the docs of action.fulfill() that "You should only call this method from the implementation of a CXProviderDelegate method". I this the reason for the issue? But how can I do it if I need to wait for the connection asynchronously and the provider method is synchronous?

Hi Team, We are facing issues about VOIP call for some users in USA who used the Wi-Fi network of some service provider. They are not receiving the calls on Wi-Fi but able to receive the call when connected to SIM/Data Connection. We implemented the VOIP services of apple and VOIP notification received and call kit UI displayed. Its working fine on public network mostly but not working on some Wi-Fi network in USA. iPhone 12 Latest iOS version VOIP notification not received Call kit not display App Name=> Owwll

Hello, I would like get advice about the time-sensitive notification ‘interruption-level’ set to ‘time-sensitive’ in the push payload. I’m wondering if this setting applies to VOIP push notifications. I tried to find information in Apple’s documentation, but it doesn’t specify whether it is applicable for VOIP push notifications. { "aps": { "interruption-level": "time-sensitive" } } https://developer.apple.com/documentation/usernotifications/generating-a-remote-notification#:~:text=ContentIdentifier%[…]terruption%2Dlevel,-String

Hi, I have implemented VOIP calling feature in my application using OpenTok SDK and CallKit framework. Calling feature is working most of the time. But there is one strange issue I have come across. During a call, if any external cellular call appears and if I decline that external call then my running voip call also disconnects. This is happening some of the iPhone devices. iPhone config is as follows Model : iPhone 11 iOS Version : 17.3 I have added loggers CXEndCallAction and -provider:performEndCallAction and debugged at my end . I found that CXEndCallAction is not executing from my end but still -provider:performEndCallAction is triggered by iOS along with my ongoing callUUID This is very strange behaviour I am observing in one of my iPhone device. I have tested this in around 3-4 iPhone devices but i am facing this issue only in 1 iPhone . Kindly help me here if anyone has solution around it . Thanks

I am facing a strange problem with PushKit/CallKit when compiling with SDK 17.x. The app behaves normally on iOS 16 and iOS 17 devices but PushKit does not seem to work properly anymore with VoIP Push messages. The behavior is as follows: when the screen is unlocked, everything works as expected (app gets automatically started when not running and the call notification is displayed) when the screen is locked and the app is already running, everything works as expected (CallKit call screen is shown) when the app is not running and the screen is locked, nothing happens... but as soon as I unlock the screen the app gets started and CallKit can be informed about the call. After this the call notification is properly displayed. In the logs of the app I can see that the app didn't get started/informed about the VoIP Push notification before unlocking the screen Now the second problem is: as iOS doesn't start the app properly when the screen is locked, the app can't display the call via CallKit. Because of that the app will get blacklisted after a while (and for a while). Before using iOS SDK 17 the app was working without any issues on iOS 15 devices. Is this a known issue?

Is there a way for the app currently playing music or voice in the background to know when a Critical Alert or push comes? Currently, my app contains code that stops playback when a call comes in while music or voice is playing in the background. So, if a call comes in during playback, it stops normally. However, there is a phenomenon in which playback cannot be stopped when a Critical Alert or push comes. When a Critical Alert or push comes to the device, is there a way in the code for the app currently playing music or voice in the background or foreground to know at that moment? We are not sending out Critical Alerts or pushes. I would like to know how to resolve the situation when receiving a Critical Alert or push sent to all users in one country.

I think I've got all the keys and entitlements set up ok. I have no problem receiving normal alerts via the UNUserNotifications framework. Now I'm trying to use PushKit (for fileProvider). I have the following in my AppDelegate fileProvider = PKPushRegistry(queue: nil) fileProvider.delegate = self fileProvider.desiredPushTypes = [.fileProvider] along with the required delegate functions. I am never provided with credentials, only an immediate call to the didInvalidatePushToken delegate. Any suggestions appreciated.

I am using Pushkit + Callkit and I am facing issue: I receive incoming call when device is locked screen state then I answer and end call. The next incoming call will alway display on left corner screen device as below image. If I receive incoming call when device is unlocked screen state, my application receive, answer call and end call normally.

Hello everyone, I am developing a feature in my app where, upon receiving a push notification, the app should open automatically if it is closed and the screen is locked. If the device is unlocked, a persistent notification should appear and only be removed with user interaction. We managed to implement this functionality on Android using some configurations and additional rules. With this, upon receiving a push notification, the app opens automatically or a permanent notification appears. I would like to know how I can implement this functionality on iOS using Swift. Is there any specific configuration or API that allows the app to open automatically upon receiving a push notification or to display a persistent notification on the unlocked screen? Thanks in advance for your help!

Setup and status: The app is under an Enterprise dev account. The app has Push Notifications, Remote Notifications and Voice over IP entitlements selected, among other, unrelated (I think) items. On launch, the app successfully registers via PushKit and gets back a valid device token. This token is copied from the Xcode console, and used to send VOIP pushes via the iCloud push console: https://developer.apple.com/notifications/push-notifications-console/ Results: For a debug build loaded onto a physical device, the push console reports successful delivery of the VOIP push to the device. However, VOIP pushes are only received by the app when it is in the foreground. If the app is in the background or not running, it is not woken/launched. The docs mention the need for a special VOIP push certificate, but my understanding is that is required between my server and Apple's servers. Since I am using the push console, I assume that removes the need for the certificate. So, what am I missing?

Hi Everyone, I am setting apns expiration in the push payload sending to apple server. push expires in 30 seconds as per the configuration using development certificates. However the same logic does not work when I use adhoc profile but works in App store . Any specific reason it does not work using adhoc profile?

It is received fine when the watch app is in the foreground.

Users of my app have reported that they are sometimes unable to receive Voice-over-IP (VoIP) push notifications when using a SIM. (There is no problem when using WiFi) VoIP push notifications were not received during the following period. Could you confirm diagnostic logs and could you please tell me why my app can't receive VoIP push?

I am working on a VoIP based PTT app. Uses 'voip' apns notification type to get to know about new incoming PTT call. When my app receives a PTT call, the app plays audio. But the call audio is not heard. While checking the phone volume, the API [[AVAudioSession sharedInstance] outputVolume] returns 0. But clearly the phone volume is not zero. On checking the phone volume by pressing side volume button, the volume is above 50%. This behavior is observed in both app foreground and background scenario. Why does the API return zero volume level ? Is there any other reason why the app volume is not heard ?

I am working on a VoIP based PTT app. Uses 'voip' apns notification type to get to know about new incoming PTT call.  When the app is in foreground, the app gets to know about incoming VoIP PTT call through incoming push notification. After receiving notification, the app receives audio from the server. This works properly, as expected. The app faces issues in receiving apns notifications only when the app is in background. Issue: My app is in background and iPhone locked, the server sends apns notification to the target iPhone about a new incoming VoIP call. Server received 200 success response code from APNS. But the app in background did not receive the notification. Second time, the server sends notification about second VoIP call. App did not receive notification. Third time, server sends notification about 3rd incoming call. This list goes on. Everytime server sends a notification to the target phone, success response is received from APNS. 
 Now, bring the app to foreground, the app receives all the pending notifications at once. This scenario happens only in a few phones. Those customers are missing PTT calls.
Can you please provide us suggestions to solve this issue ? My app uses unrestricted-voip entitlement
