If you answer an new invite for a room with an inbound call, CallKit doesn't show until you go back to the index page

Although you do get a red hangup button as if you were in the call (except you're not). This obviously makes it impossible to receive calls from new users...

Start by reproducing the sequence described: answer a new room invite while an inbound call arrives, then inspect the CallKit integration and the transition back to the index page. Done means CallKit appears without navigating to the index page and the call state does not show a hangup button for a call that was not connected.
