I am developing a VOIP app which should also work in China region. I want to detect whether there are any other calls active or ended. This functionality is can be achieved using Callkit CXCallObserver. But CallKit cannot be used in China. So is there any other alternative way to achieve what CXCallObserver offers?

We have a voip calling app which supports multiple calls at the same time.
Problem is, if a user is on 1st voip call, mutes it and then holds it to accept 2nd voip call, the 2nd voip call does not have an outgoing audio.
This means, it appears as if the 2nd voip call has been muted. Incoming audio works properly.
Is this working as expected with Callkit?
