While researching VoIP push notifications we can across this thread. You mention in your reply that “your app will be terminated if you receive a VoIP push that does not end up in a call, and will be blocked from receiving further VoIP pushes after a while”. We would just like to confirm our assumption that as long as an inbound VoIP call is announced to the user (system call UI) then regardless of the outcome (answered, rejected, or ignored) then the device will continue to be able to get VoIP pushes and wake up the app in the background. Also if for some reason the user presses accept and the call does not start (server error, etc) will iOS start to block that app? Thank you!
