Hello,
I currently can’t start phone calls with my Librem 5. Incoming calls work fine, but when I start a call, it usually terminates when the other party picks up.
Yes, I did some experiments regarding the installation of Plasma Mobile … so I reinstalled pureOS stable now without any modifications, but the problem persists.
Are there such weird things like call progress tones to be set up correctly like with SIP telephones?
What is the firmware version shown in the BM818 Tool app? If you don’t have that installed yet: sudo apt install bm818-tools
You’ll need it to activate VoLTE.
You might want to mask your IMEI in your post above. It’s a unique identifier for your device.
VoLTE is now enabled after reboot. I tried a call, it took quite long, til it started ringing, but then the other party could pick up successfully. I have LTE here. Ok, this was just one try. I will test further.
