reportIncomingCall while in foreground

Hi,

I'm emplimenting VoIP functionality using CallKit. I have major issue with incoming calls. Currently if I use CXProvider method reportIncomingCall system incoming call UI is shown even if my application in foreground. I'm interested to show internal incoming call in this case while letting OS know that there was incoming call. I checked docs and tutorials but can't find how to implement requered behavior. Am I missing something?


Thanks
