I am trying to send VOIP push to the user.
While the app is in the background, it crashes with the following error: 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push callback.'
IOS13, OneSignal and Sinch
2019/11/12 | SINCH SDK IOS 4.1.0
iOS 13 VoIP push and CallKit compatibility. When linking against
the iOS 13 SDK or later, your application must report VoIP push
notifications as an incoming call to
managedPush:didReceiveIncomingPushWithPayload:forType:] will now
be invoked synchronously on Sinch-internal GCD queue as assigned
to PKPushRegistry so that an application can report to CallKit
within the same runloop as mandated by the iOS 13 changes
