Hello wangxiaoqi ,
We only support APNs Token-based authentication. We no longer support APNs certificate-based functionality.
Please review our documentation here:

May I ask why I have configured the push certificate and code according
to the steps in this document, but I cannot receive the push
notification of incoming
calls?https://developers.sinch.com/docs/in-app-calling/ios/push-notifications-callkit/
