On iOS, when app is in background or killed state, and receive and pickup the incoming VoIP call. After if I tap on "Mute" button to mute the call, it gets selected for few seconds and then it gets automatically deselected on System-calling native iOS callkit dialer(UI) .
There are no code written for mute/unmute part on my CXProviderDelegate or any other place in my app. So not sure what could be the reason of this behavior. Any idea?
