As per earlier feedback from Apple's Engineering team, they believed that the issue was addressed and a fix would've been available in the next update. iOS 12 GM Seed is now available for download. We've tested the issue on iOS 12 GM and the issue still persists!

Thanking the Engineering team for a positive update. I'm assuming that "future iOS update" would mean iOS 12 beta 13 or any further iOS 12 beta releases before the final GA. Is that correct information? Eagerly waiting to hear from you regarding the beta update on which the issue can be retested. Thanks again.

This is to inform that we've tested with iOS 12 beta 12 on August 31 and same behaviour is still being observed - Application isn't waking up during an incoming VoIP socket activity. Can you review the attached sysdiagnostic logs at the earliest. As mentioned earlier, customer impact is going to be high if the issue remains unresolved by the time iOS 12 is GA'd
