I am facing this issue as well

The plugin won't save the call information if the app is killed and the plugin isn't set up. You can either initialize and register in the background or save the call information so the app can read it once it is in the foreground again.

@victortive do you have any suggestions on how to use the saved call? Because in the cases the call arrives after a notification in killed state, the SipUaHelper instance is not the same on the background isolate and main isolate

[victortive]

if the SipUaHelper is not the same instance consider wrapping it in a class and making that class a singleton

[eduardothiesen]

I did that, but single isolates don't share memory, it does not work Em ter., 6 de ago. de 2024, 17:42, Victor Uvarov ***@***.***> escreveu:

try saving it in shared preferences on the native side and reading it on the dart side

[eduardothiesen]

I don't know if that would work. Since shared preferences only accepts serializable types and also if I save let's say, the informations of the call, I think it's not possible to attribute the saved call to the new instance SipUaHelper

One way to work it out is, keeping the SIPUAHelper in background isolate and sending only the neccessary information to the main isolate.

In your case, send the call ID to background isolate, find the Call, handle it there and send those UI related infos to main isolate like for showing active call or any as you prefer.

But one constraint here is the video call implementation. As we need to pass MediaStream to main isolate and we can't serialize it.
