Thanks for posting this question rmendes22.
This VOIP Pushkit Anomaly deserves an official answer from Apple.
Our company had to shelf development of our App (3 years worth of development) as it used the VOIP push kit occasionally under special circumstances to reliably wake up the App in the background .... without it, our app's behaviour is unpredictable and unusable.
Any updates on this would be great.
Thanks a ton guys!
