Android-iOS VOIP notifications not working as expected

[joeyoggie]

Hi,

We are building an appointments based app between patients and doctors. We are currently having issues sending notifications between Android and iOS.

We use a custom payload with notifications to detect the type of the appointment (voice call or video call)

The following scenarios work: Android > Android normal notification works fine iOS > iOS normal notification works fine Android > iOS normal notification works fine iOS > Android normal notification works fine

However, Android > iOS VOIP doesn't work. Nothing is received on the iOS device, even though the notification appears on the ConnectyCube Admin Panel notifications' queue.

Here's the method that sends the notification from Android to iOS: `

private void sendiOSVoipNotification(){
    Log.d(TAG, "sendiOSVoipNotification to " + partnerEmail + " - userId: " + partnerUserId);
    StringifyArrayList<Integer> userIds = new StringifyArrayList<>();
    userIds.add(partnerUserId);

    ConnectycubeEvent event = new ConnectycubeEvent();
    event.setUserIds(userIds);
    event.setEnvironment(ConnectycubeEnvironment.PRODUCTION);
    event.setNotificationType(ConnectycubeNotificationType.PUSH);
    event.setPushType(ConnectycubePushType.APNS_VOIP);

    JSONObject json = new JSONObject();
    try {
        json.put("notificationType", Constants.NOTIFICATION_TYPE_CALL);
        json.put("appointmentID", appointmentId);
        json.put("patientName", patientName);
        json.put("patientEmail", patientEmail);
        json.put("consultantName", doctorName);
        json.put("consultantEmail", doctorEmail);
        json.put("consultantImageURL", doctorImageUrl);
        json.put("date", dateString);
        json.put("timeTitle", timeString);
        json.put("communicationID", appointmentType);
        json.put("message", "Incoming Call. Tap to answer or reject");

        json.put("opponentId", personalUserId);
        json.put("recieverEmail", partnerEmail);

        json.put("calluuid", UUID.randomUUID().toString());
    } catch (Exception e) {
        e.printStackTrace();
    }

    //event.setMessage("");
    event.setMessage(json.toString());

    Log.d(TAG, "Data: " + json.toString());

    ConnectycubePushNotifications.createEvent(event).performAsync(new EntityCallback<ConnectycubeEvent>() {
        @Override
        public void onSuccess(ConnectycubeEvent event, Bundle args) {
            Log.d(TAG, "sendiOSVoipNotification createEvent onSuccess");
        }

        @Override
        public void onError(ResponseException errors) {
            Log.d(TAG, "sendiOSVoipNotification createEvent onError: " + errors.getMessage());
        }
    });
}`

For reference, here's the iOS method:

    let event = Event()
    //event.notificationType = .push
    var opponentID :UInt?
    if let opponentTemp = self.view?.opponentUser {
        opponentID = opponentTemp.id
    }
    else if CallVOIPHelper.instance.opponentId != nil {
        opponentID = CallVOIPHelper.instance.opponentId?.uintValue
    }
    else {return}
    //guard let userId = self.view?.user?.id else {return}
    event.usersIDs = [opponentID!] as [NSNumber]
    event.type = .oneShot
    event.pushType = .APNSVOIP
    var pushParameters = [String : String]()
    pushParameters["message"] = "\(AppData.shared.isDoctorProfile ? AppData.shared.userData?.profile?.fullName ?? "" : AppData.shared.userData?.fullName ?? "")"
    //pushParameters["ios_badge"] = "2"
    //pushParameters["ios_sound"] = "app_sound.wav"
    // custom params
    if let session = self.session {
        pushParameters["patientName"] = session.patientName
        pushParameters["consultantName"] = session.consultantName
        pushParameters["date"] = session.date
        pushParameters["timeTitle"] = session.timeTitle
        pushParameters["communicationID"] = String(session.communicationID ?? 0)
        pushParameters["consultantImageURL"] = session.consultantImageURL
        pushParameters["consultantEmail"] = session.consultantEmail
        pushParameters["patientEmail"] = session.patientEmail
        pushParameters["appointmentID"] = String(session.appointmentID ?? 0)
        pushParameters["notificationType"] = NotificationType.call.rawValue
        pushParameters["calluuid"] = UUID().uuidString
        pushParameters["recieverEmail"] = AppData.shared.isDoctorProfile ? session.patientEmail ?? "" : session.consultantEmail ?? ""
        pushParameters["opponentId"] = "\(self.view?.user.id ?? 0)"
    }
    print("DEBUG INFO: call notification push parameters : \r\n\(pushParameters.debugDescription)")
    if let jsonData = try? JSONSerialization.data(withJSONObject: pushParameters,
                                                  options: .prettyPrinted) {
        let jsonString = String(bytes: jsonData,
                                encoding: String.Encoding.utf8)
        event.message = jsonString
        Request.createEvent(event, successBlock: {(events) in
            print("success")
        }, errorBlock: {(error) in
            print("error , \(error.localizedDescription)")
        })
    }

For sending APNS_VOIP notification from Android just add the next parameter

json.put("ios_voip", 1);

to your JSON. About specific parameter for push notifications you can read there https://developers.connectycube.com/server/push_notifications?id=universal-push-notifications

[joeyoggie]

@TatankaConCube I tried adding that key to my json, but still the same. The notification appears on the Admin Panel, but the iOS device doesn't start the incoming call UI. The iOS can receive normal notifications though, it's only VOIP ones that are missing.

Here's a video of it in action: https://drive.google.com/file/d/1WCb4ItX4lJFRuGmmK6xNVSK9fBcBmdf5/view?usp=sharing

[TatankaConCube]

Can you please provide more status info about this notification? For it click on the 'sent' link on your screenshot and download JSON with the full report.

[TatankaConCube]

Additionally provide to us logs from the logcat with event creation

[joeyoggie]

@TatankaConCube here are the complete logs:

ConnectyCube Admin Panel notification json file: 3438214_log.json.gz

Chat initialization log: connecting_to_chat_log.txt

Sending notifications log: sending_notifications_log.txt

[TatankaConCube]

I will study your data tomorrow. For today try to delete this parameter event.setPushType(ConnectycubePushType.APNS_VOIP); and add json.put("ios_voip", 1); as I wrote before. In this case, SDK will send a universal push notification, and type will be used from your json.

[TatankaConCube]

@joeyoggie did you try my latest suggestion?

[joeyoggie]

@TatankaConCube Yes, I tried it when you first suggested it, but it was the same result. Notification sent and shows on the Admin Panel, but it's nothing on the recepient iOS device.

[TatankaConCube]

Did you delete pushType parameter from the event?

[joeyoggie]

Yes, indeed. I removed it and added 'ios_voip' to the json payload.

[TatankaConCube]

Hmm, it should work. Can you please provide the same log from the admin panel for the event, sent from iOS?

[joeyoggie]

@TatankaConCube sorry we had some issues in our BE server.

Here are the logs: Android > iOS: (nothing received on iOS device) 3672087_log.json (android to ios).gz

iOS > Android: (works fine) 3672127_log.json (ios to android).gz

Edit: By nothing is received on iOS, I mean no VOIP calling received, I still however receive a normal notification message with 'Incoming Call. Tap to answer or reject' text I send in the 'message' field in the json payload.

[TatankaConCube]

I mean logs about worked push notification from iOS to iOS. Can you provide it?

[DaveLomber]

hi @joeyoggie

just to confirm couple of things:

Do you subscribe for VoIP push notifications? I mean , for iOS, you need to have 2 separate push subscriptions: one for normal pushes and another one for VoIP pushes.

Please confirm you do 2 push subscriptions on iOS

Here is more info regarding ios_voip parameter:

ios_voip=1 - will initiate VoIP push notification for iOS if user has VoIP push subscription. Otherwise - iOS user will receive standard iOS push. For Android - it will be a standard push.

So if a user has only normal pushes subscription then it will be a normal push initiated, despite you provide ios_voip=1.

[joeyoggie]

@TatankaConCube the above notification is the same one sent from iOS to iOS. I'll try and get you another log for iOS-iOS notification payload soon

@DaveLomber Yes, iOS is subscribed to VoIP.

[joeyoggie]

@TatankaConCube here's the iOS-iOS notification: 3713856_log (ios to ios).json.gz

[DaveLomber]

@joeyoggie so

same request with same payload

iOS->iOS works, but Android->iOS is not?

[joeyoggie]

@DaveLomber yeah exactly. iOS doesn't open the incoming call screen at all when calling from Android.

[DaveLomber]

@joeyoggie please show a code snippet how you create an event from iOS we need to compare with Android code above

[joeyoggie]

@DaveLomber here you go:

let event = Event()
    //event.notificationType = .push
    var opponentID :UInt?
    if let opponentTemp = self.view?.opponentUser {
        opponentID = opponentTemp.id
    }
    else if CallVOIPHelper.instance.opponentId != nil {
        opponentID = CallVOIPHelper.instance.opponentId?.uintValue
    }
    else {return}
    //guard let userId = self.view?.user?.id else {return}
    event.usersIDs = [opponentID!] as [NSNumber]
    event.type = .oneShot
    event.pushType = .APNSVOIP
    var pushParameters = [String : String]()
    pushParameters["message"] = "\(AppData.shared.isDoctorProfile ? AppData.shared.userData?.profile?.fullName ?? "" : AppData.shared.userData?.fullName ?? "")"
    //pushParameters["ios_badge"] = "2"
    //pushParameters["ios_sound"] = "app_sound.wav"

    // custom params
    if let session = self.session {
        pushParameters["patientName"] = session.patientName
        pushParameters["consultantName"] = session.consultantName
        pushParameters["date"] = session.date
        pushParameters["timeTitle"] = session.timeTitle
        pushParameters["communicationID"] = String(session.communicationID ?? 0)
        pushParameters["consultantImageURL"] = session.consultantImageURL
        pushParameters["consultantEmail"] = session.consultantEmail
        pushParameters["patientEmail"] = session.patientEmail
        pushParameters["appointmentID"] = String(session.appointmentID ?? 0)
        pushParameters["notificationType"] = NotificationType.call.rawValue
        pushParameters["calluuid"] = UUID().uuidString
        pushParameters["recieverEmail"] = AppData.shared.isDoctorProfile ? session.patientEmail ?? "" : session.consultantEmail ?? ""
        pushParameters["opponentId"] = "\(self.view?.user.id ?? 0)"
    }

    print("DEBUG INFO: call notification push parameters : \r\n\(pushParameters.debugDescription)")
    if let jsonData = try? JSONSerialization.data(withJSONObject: pushParameters,
                                                  options: .prettyPrinted) {
        let jsonString = String(bytes: jsonData,
                                encoding: String.Encoding.utf8)

        event.message = jsonString

        Request.createEvent(event, successBlock: {(events) in
            print("success")
        }, errorBlock: {(error) in
            print("error , \(error.localizedDescription)")
        })
    }

[DaveLomber]

You do not need this event.pushType = .APNSVOIP Just remove it as suggested above for Android

Then, also pass ios_voip=1

so it should be the SAME payload for both iOS/Android sides, please align

[joeyoggie]

@DaveLomber ok will remove it, but it works with it anyway.

[TatankaConCube]

in this case, you will have the same data from iOS and from Android in your callback

[joeyoggie]

@DaveLomber there's another issue, as you can see from the above screenshot, the iOS received the VoIP notification, but when we answer the call, nothing happens. It says 'BeSure audio connecting..." and that's it. It was working fine 10 days ago, and we haven't changed anything in the build as it's the same one on the App Store.

No activity for a long time. Closing... If you still have the same error, please create a new ticket with details.
