if My app works at background, can I use silent push to wake app and get the VOIP call?
I used "jpush" to post a silent push which can work when connecting my idevice with Xcode and run APP.
If my idevice doesn't run APP with Xcode, I can not receive the silent push at background (only receive at foreground.)
Is it possible to use silent push to wake up APP and get VOIP call?
Did I get something wrong??

Yes. If your application does VoIP calling then it's possible to use PushKit:
Overview
The PushKit framework sends specific types of notifications — such as VoIP invitations, [...] — directly to your app for processing. [...]
Unlike user notifications, which are supported by the UserNotifications framework, PushKit notifications are never presented to the user — they don't present badges, alerts, or sounds.
PushKit notifications offer the following advantages over user notifications:
- If your app isn't running, the system automatically launches it upon receiving the notification. [...] For more information, see Local and Remote Notification Programming Guide.
- Your app is given runtime to process the notification, even if it's running in the background.
