[Linphone-developers] Dear Linphone Support Team

[Patryk Matwijczuk]

Dear Linphone Support Team,

I am currently integrating SIP calling functionality into a mobile application developed using Xamarin for both iOS and Android platforms. I came across Linphone as a potential library for this purpose, but I am facing issues with the integration process, especially with compatibility concerning the latest Android SDK 34. I am currently using libraries from NuGet: https://gitlab.linphone.org/api/v4/projects/411/packages/nuget/index.json

Current error:

```

04:23:51 [MESSAGE] (liblinphone) Sal nat helper [enabled]

04:23:51 [FATAL] (mediastreamer) Calling ms_get_jni_env() while no jvm has been set using ms_set_jvm().

```

Do you have any suggestions on what might be causing the issue?

Moreover I have a few questions:

1. Starting from which version does LinphoneSDK support .NET 6 and beyond?

2. Is LinphoneSDK.Xamarin the last version that supports Xamarin with .NET Standard 2.1? 

3. Development Roadmap:

Is the LinPhone library actively maintained with plans for continued support and updates? Knowing this would be helpful in making long-term planning decisions for our application.

I appreciate any insights you can provide regarding these questions and any additional guidance for integrating LinPhone into a .NET ecosystem app. Thank you in advance for your assistance.

Best Regards,

Patryk
