        AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
            if granted {
                Linphone.manager.callUser(username: username)

                print("granted")

                do {
                    try session.setCategory(AVAudioSessionCategoryPlayAndRecord)
                    try session.setActive(true)
                }
                catch {

                    print("Couldn't set Audio session category")
                }
            } else{
                print("not granted")
            }
        })
