I'm facing a problem when implement linphone iOS native for a Voip Flutter application. Of course, the app must use callkit to notifcation have a call is comming. When user pick up the call, audio active well. But, after that, I start call out and get no audio. I try many solutions but not works (delay start call, force set active AVAudioSession...) but no luck, please help me handle this case. Thank you!
