can't navigate to call screen after picking call from notification when app is killed

[Ahtsham0715]

I have a phone app and I implemented calls using flutter_webrtc and sip_ua it works fine in foreground mode but when the app is killed I used flutter_callkit_incoming to show call notification, upon call accept I'll be able to pick the call but can't navigate to call screen because when the app starts from killed state it does not have Call data which is required to pass to callscreen.

[victortive]

You can save the call data in shared preferences and when the flutter app opens, you can read from the call data shared preferences and then pick up the call.

1. Get notification
2. Open app
3. Register SIP
4. Depending on server. Read call data from preferences or the server sends the incoming call again once connected

[Vinayak0-0]

@victortive shared one way to get it done.

Another way is to run the SIP as a background service.

[Ahtsham0715]

I tried both but nothing worked

[pogenz45]

when reconnect sip after have notification, tell server send the call again, this'll work. i solved this I tried the way @Vinayak0-0 tell. Keep socket connect, it's worked But it work in 1 extension situation. when ring ingroup(ring many extensions), it's not work with that way

[pogenz45]

The best way is keep connect socket (Use flutter_foreground_task), listen state call in background and show notification when call coming. When accept the call, use findCall function to reconnect the call in background But still now, i not resolve this because not handle flutter_foreground_task when findCall (Helper not same when reopen app so no find the call) Anyone solve this problem

[Vinayak006]

@pogenz45 If you keep the SipUAHelper in background, it will be same as when the background service was started.

TaskHandler will be like:

class MyTaskHandler extends TaskHandler implements SipUaHelperListener {
  final SIPUAHelper sipuaHelper = SIPUAHelper();
  .....
  .....
}

That way the helper will be same as it was created.

but in main state,how can i get this sipuaHelper?

[Vinayak006]

@pogenz45 , you don't need the helper in main isolate. You should handle everything related to helper in background isolate and send the necessary data to main isolate to update the UI

Hello, have you found a solution for this issue? I am experiencing the same problem in the background. When you find a solution, can you share it with me?

[paulodrikey]

I’m having the same issue. When I answer with the app closed, the audio works, but it doesn’t open the call screen… has anyone managed to solve this problem?

[robsonvasquez]

I'm experiencing the same issue: the VoIP call runs, but the app can't capture the 'call' object from SIP UA, and it doesn't navigate to the call screen when initiated by CallKit. Has anyone managed to solve this?

You can only capture the call when keep connection onl When awake app and reconnect sip, you cannot find the call through call_id or capture the call I resolved it, when have callcoming, server will check and send request to offline_ext every 0.2s until the ext online so when you reconnect app, you'll capture the call

When I receive a notification from FCM, I register with the SIP server (Asterisk). Shortly after, I receive a call invite via SIP UA and trigger the callkit incoming notification, all while in the background. When the user accepts the call by clicking "Accept" on the callkit, my app is launched, and the call is answered using call.answer from SIP UA. I check on the native Android side if the app was initialized by the callkit library and navigate to my call screen. The call and audio traffic work, but I don't have access to the SIP UA call object that initiated the call. It seems as though the SIP call is happening in a different "thread" while the app is running on another with a new instance of the SIP UA helper. When I retrieve the call.id and try to find the call with findCall(), it returns null. However, the call is ongoing since I can hear and respond to the audio.

the problem is if you handle reconnect sip in function onbackground message of firebase SipuaHelper will declare in background and when you open app, main isolate will declare new sipuahelper so this helper not ablle to find the call through call_id Use flutter_foreground_task, my idea is when. receive notifi, start_foreground_task(reconnect sip inside this method and listen call state, also use flutter_callkit_incoming to show ring notifi) -> accept the call (set call.accept) -> now app will receive voice but not update ui yet -> use function sendDataToMain of flutterforegroundtask to update UI and function sendDataToTask to handle back of background

Hello, in the example you sent, when the first call comes, it establishes the voice connection that you answer, but the call greeting screen closes and the voice continues, and also when I add callkit, when a call comes, the callkit notification is instantly shown multiple times, how can I show this only once?

Aynı sorunu yaşıyorum: VoIP araması çalışıyor, ancak uygulama SIP UA'dan 'arama' nesnesini yakalayamıyor ve CallKit tarafından başlatıldığında arama ekranına gitmiyor. Bunu çözmeyi başaran var mı?

Bağlantıyı açık tuttuğunuzda yalnızca aramayı yakalayabilirsiniz. Uygulamayı uyanıkken ve SIP'i yeniden bağladığınızda, call_id aracılığıyla aramayı bulamazsınız veya aramayı yakalayamazsınız. Sorunu çözdüm, gelen bir arama olduğunda, sunucu kontrol edecek ve dahili hat çevrimiçi olana kadar her 0,2 saniyede bir offline_ext'e istek gönderecek, böylece uygulamayı yeniden bağladığınızda aramayı yakalayacaksınız.

FCM'den bir bildirim aldığımda, SIP sunucusuna (Asterisk) kaydoluyorum. Kısa bir süre sonra, SIP UA üzerinden bir çağrı daveti alıyorum ve callkit gelen bildirimini tetikliyorum, hepsi arka planda. Kullanıcı callkit'te "Kabul Et"e tıklayarak çağrıyı kabul ettiğinde, uygulamam başlatılıyor ve çağrı SIP UA'dan call.answer kullanılarak yanıtlanıyor. Uygulamanın callkit kitaplığı tarafından başlatılıp başlatılmadığını yerel Android tarafında kontrol ediyorum ve çağrı ekranıma gidiyorum. Çağrı ve ses trafiği çalışıyor, ancak çağrıyı başlatan SIP UA çağrı nesnesine erişimim yok. SIP çağrısı farklı bir "iş parçacığında" gerçekleşirken, uygulama SIP UA yardımcısının yeni bir örneğiyle başka bir iş parçacığında çalışıyor gibi görünüyor. call.id'yi aldığımda ve findCall() ile çağrıyı bulmaya çalıştığımda, null döndürüyor. Ancak, sesi duyabildiğim ve yanıtlayabildiğim için çağrı devam ediyor.

in event accept_call of flutter_incomingcall, why don't you set navigator to call_screen and handle call.answer in that screen?

[pogenz45]

and problem multitime, just showcomingcall in stateCallEnum.CALL_INITIATION

Here’s an example of how to use Callkit with FCM, Sipua, and WebRTC on Android. As explained in the FCM documentation, when using the onBackground method in Android, it creates a separate isolate from the main app's isolate. So, when I receive a call notification in the background, I authenticate the Sipua helper in the FCM isolate. Once the main isolate starts, I exchange information between the isolates to manage the Sipua Call and the app interface. If the notification is received while the app is in the foreground, the Sipua registration happens in the same main isolate without needing to exchange information between isolates. For iOS, according to the FCM documentation, a separate isolate is not created for onBackground, so it works normally. You only need to obtain the token to receive the PushVoIP notification on iOS.
