Describe the bug
After upgrading flutter_webrtc from ^0.14.1 to ^1.0.0, the microphone stops working on the second call in iOS.

• First call: microphone works fine.
• Second call: microphone does not work unless the app is completely restarted.
• Issue does not occur on Android.
• Downgrading back to ^0.14.1 fixes the problem.

To Reproduce

1. Start a call (microphone works).
2. End the call.
3. Start another call.
4. Microphone does not work.

Note: The problem does not occur if you completely close and restart the app between calls.

Expected behavior
The microphone should work in every new call without restarting the app.
