Socket connection is disconnected if the screen is locked


Hi i am developing a voip application. There was a problem on ios 13. When an application receives a voip push it init a socket connection and sometimes it disconnects when the screen is locked. As far as I understand, this should not be the case if you use a bunch of callKit and voip push. If someone came across such a problem, please tell me how to fix it. info.plist includes backgroundModes. thanks
