Hello,
I received my Librem5 last year. I live in Europe and my provider is Telekom. When I check my provider’s config, VoLTE is enabled. As I read above, maybe there is a problem with Telekom…reagrdless I tried to enable VoLTE and here is my story:
I regulary update my system with
sudo apt update && sudo apt full-upgrade
sudo reboot
I currently run byzantium and kernel 6.1.0-1-librem5 (manually installed by sudo apt install linux-image-6.1.0-1-librem5).
Today I installed bm818-tool using apt. After installation I reboot my system and start the gui tool. In that tool I opt-in VoLTE enabled and reboot again. Afterwards I startet a call to my home and checked wit the gui tool for VoLTE but nothing happens.
On the top under FW version it is written:
M100E_YCSN0_1.0.0_210122
YCSN0_M100E_1BAD_3117_V1.0.0.1_20210906
M100E_1.0.4_200715
So, IMO VoLTE don’t work for me. Do I have to update my firmware as mentioned above? If the update process ist still critical, I will wait until there is an official and save way to do the update. @Purism what’s the current state?
Other question:
What means CBS enbale in the bm818 tool?
