As the title, I just want to receive a VoIP message, then do something.
But it seems to be necessary to do reportNewIncomingCall in didReceiveIncomingPushWith, and it will make the call shows up.
Can I cancel the call before it shows up ?
Can I use PushKit but don't make a call?
You can report and not show the Call screen, using this.
For example using current date: Date() and choosing a reason like .unanswered.
So it will be reported kinda "silently", can't say is the most recommended approach but it may for you as of now.
