I was having that problem. Solved it by unistall viper on magisk then rebooting phone and then installing again and rebooting. Dont know why but it worked.
Does this post support VoLTE?Well done...

They gave you a solution you don't want to try. If you aren't willing to change something to make it work then don't post issues and ask for help

At the end of the day it's your ROM.
Frankly all this VoLTE talk is incredibly annoying. If people want it so bad, they can learn to code and make their own.
