Using IOS SDK is it possible to detect an incoming call when another call is inprogress (in background)?

Question

I am aware that we can get the call state info using CoreTelephony framework (using CTCallCenter).If a call is already in progress,is it possible to detect the new incoming call and one more thing is it possible to track the incoming calls in the background application.

background app in iOS that detects incoming phone calls

From the above links, I think it is not possible to run the app in background.Is there any other approach to achieve this ?

Answer 1

It looks like it is not possible with the current sdk.
