We just add VOiP capability to our app (messaging app), now we will use VOiP (PushKit Framework).
Can anyone tell me if we can use only that notifications (VOIP notifications)? Meaning even for text message for example (not for a call)? I talk about Apple Appstore Guides, they can reject the app or block the notifications if they found that we use that notification to notify the user about other things then a VOIP call?
The answer is yes, i used the VOiP notification for a no-voip notifications (like a text message) and Apple accept the app (and i can can confirm, after some tests, that whatsapp use the same thing as my app).
You need to implement VOIP functionality in order to not to be rejected. I've tried to use it for messages between users and it was not approved. So if you really don't have VOIP functionality, modify your server to your needs.
I have also implemented VOIP push notification in our app. But app is rejected by app store by saying "We continue to find that your app declares support for VoIP in the UIBackgroundModes key in your Info.plist, but it does not include any Voice over IP services.
Please revise your app to either add VoIP features or remove the "voip" setting from the UIBackgroundModes key.
We recognize that VoIP can provide "keep alive" functionality that is useful for many app features. However, using VoIP in this manner is not the intended purpose of VoIP.".
