Fix ringing calls not stopping when the other user cancels the call (#4613)

* Fix ringing calls not being automatically canceled

This will keep the sync active while the user is screening an incoming call, allowing receiving a call cancellation event, which will terminate the incoming call ringing early.

* Add extra logs to help debugging ringing call issues.
