Callkit issue on my voip ios app(swift)

Job ID: 31928644

Budget: ₹1,500 – ₹12,500 INR

Hi,
I have an Iphone VoIP app (written in swift) used for making and receiving calls.
I am using linphone sdk for voip.
I am facing following issues with it.

1. Double calling screens -- app screen and callkit screen both visible at same time it should only show one.
2. When callkit ui is presented on incoming call and you answer the call it does not get connected and both parties not able to talk.

Here is what needs to be done :

When some one dials the number on the app (when incoming call comes on the app) no matter if the app is in background or foreground or in killed state.
The user should be able to Answer the call and should be able to talk to other party who has dialed number.
Only one calling screen should be presented.

Thanks
