Fix "not receiving incoming calls using Darklord Note 5 port"

I have a N900T and i had issues receiving calls in the darklord note 5 port and my solution was finding that there's an option in call settings "Voice over LTE settings" that was the cause of the issue...here is what i did (i hope this can help everyone having this issue)
Steps:
1- go to Settings/Applications/Phone
2-inside phone settings you will see the option "Voice over LTE settings",and this option ask you to choose between "Use VoLTE when available" or "Do not use VoLTE"
3-choose the option "Do not use VoLTE"
