I have just tested voLTE on my FP4 and I have an odd issue. If anyone calls me, the number is unknown. If I disable voLTE, then the ID of caller is the one from the Contacts app.
Is that a bug or do I have to do some magic around it?
ps. I have the lastest eOS 1.8.1 and this is my first time testing the voLTE

I’m sorry that I can’t provide any help, but this seems to be related to the same issue that I have encountered on my FP3:
