Pixel 6 pro trouble with Out Going calls ( Not resloved)

faceless_warrior

I don't use an eSIM card. I have a regular SIM card, and when I installed GrapheneOS on my Google Pixel 6 Pro, I immediately noticed that the device recognizes the regular mini-SIM card. After manually setting up the access point (APN), the internet works fine with the same SIM card, but calls are impossible. When attempting to make an outgoing call, it immediately ends without any reason. Please help me understand the reason for this problem so that I can solve it. I am attaching a screenshot here

Thank you, the following helped:

Reset Mobile Network settings in Settings ➔ System ➔ Reset options ➔ Reset Wi-Fi, mobile & Bluetooth and then reboot the device.

faceless_warrior That's great, thank you for your feedback. I'll mark this as solved, but do let us know if you have any further issues.

Sounds like you might've enabled LTE only mode without your SIM supporting VoLTE. Same behavior.

I am new to this forum and do not know where to ask questions so that the moderator does not redirect them so I would be very grateful if you could help me to publish this question in the correct forum branch: I would like to take this opportunity to ask a question that worries me... In the latest updates a function of recording phone calls was added, but I want to note that this function is still far from perfect and its quality leaves much to be desired. I would like to know if the developers are working on this problem and whether we should expect improvements in call recording quality. will it be possible to perform this action in fully automatic mode? will there be added additional formats of recorded audio files such as mp3?
