Handling VoIP notifications (additional points)

Please be notified that the handling of VoIP notifications in the background/non-running state isn't part of QuickBlox SDK's and the implementation of that functionality is up to the client-side.

You can check the correct implementation and working of VoIP notifications in the background/non-running state on the clear QuickBlox iOS WebRTC sample, that you can find by this URL: https://docs.quickblox.com/docs/code-samples#video-calling-samples

Also, please check further documentation https://docs.quickblox.com/docs/ios-push-notifications#receive-voip-push-notifications

These articles will be useful for further implementation of VoIP functionality on the client side, please check:
