Receive incoming calls while in background without push notifications

Hi

I have a peer to peer VoIP application supposed to work without Internet access. Everything works fine except incoming calls reception while in background. I know that the recommended approach for VoIP applications is to use push notifications, but this is not an option for this application. Are there other options to receive incoming calls while in background ?

thank you

I have discussed with Apple technical support about this. At this moment it seems that VoIP applications in background can receive incoming calls by using either a public or a private push notifications server.

I have opened a feedback with Apple for this:
