Outgoing calls cannot be established

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?
  • Can I debug a phone call?
  • Does someone else has this problem?
