Strange Problem with VoLTE on Mi11 Ultra

[Fordsierra88]

Hello dear community.

Xiaomi Mi 11 Ultra CN (12+512GB)
Provider "Post" from Luxembourg.

Since I have the Xiaomi.eu Rom (the weekly version) on my Mi11 Ultra, I have the problem that when I have VoLTE activated, all calls come in as unknown. When I deactivated VoLTE, the number is displayed normally.

The day before yesterday, I flashed the Global Rom from Xiaomi and it worked normally. I also have the same problem with VoLTE under the Xiaomi.eu stable. I had already contacted my provider about it but according to the provider it should work. I have already tried with other smartphones (Oppo Huawei, Vivo) and it works.

On my Xiaomi Note 7 with Xiaomi.eu (12.5.3) I don't have the problem, which I find strange.

Does anyone else have this problem?

thank you

No such thing with o2 or Vodafone here in Germany, did you try to swap the slot?
