We have modified the program as we received in the previous(thread 764479) issue.
Our program works very well and the notification problem has been almost solved in the test.
Then, we tested it in the user's environment. At that time, one of the three iPhones stopped receiving notifications. After 10 minutes, VoIP notifications were received again.
This device received PUSH notifications even when VoIP notifications did not come.
We must explain to the user why this incident occurred. We would like to know if these three notifications were sent correctly to the device. Also, is there any other way for us to deal with this other than improving the network?
