swift - iOS 13 callkit crash when app in background using sinch

Question

Using call kit, push kit and Sinch for the audio-video call. The call is working fine when app is active but crashes when the app in the background

Assertion failure in -[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes], /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/PushKit/PushKit-37/PKPushRegistry

** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push callback.' ***

The issue is on StackOverflow but unable to fix solution

Answer 1

have you used our CallKit sample voice App?

Are you able to reproduce the same error when using our sample apps?

We'll need your Sinch account info and a callID of the failed calls using our sample apps to track your issue.

Thank you Sinch Voice & Video Team
