Piling on the love here, and also want to say I haven’t forgotten I promised to DM you some journalctl output re: my 3 P-CSCF addresses that behaved differently. Things have just been really hectic, but I want to get it done real soon™

After some more struggling it’s finally working! 🥳

My provider is called Phonero, in Norway. But they rely on Telia as network provider, so I assume both can be added as verified working, with the caveat that I don’t have a subscription with Telia directly.

I managed to get the p-cscf off my Fairphone 4 actually, running “vanilla” LineageOS, with a weird caveat: I got 3 different IPV6 addresses from telephony.registry. I tried the first, and while it worked to call my partner, their phone (iphone) showed a really strange 15 digit number that their provider (Telenor) identified as coming from the Czech Republic. It didn’t have a +xx country code though. Tried again with the second P-CSCF address, and now it’s working as expected. My partner sees my 8 digit norwegian number when I call them, and receiving calls worked fine for both addresses (she could call my actual number when using the first address too). I can send you more information on the addresses here or through DMs if you want, I’m not sure how private these addresses are supposed to be, or if the “Czech” number can be tied to me.

Sorry to bother you again, but happy to report I have your image running with at least sms+mobile internet working! But I’m currently stuck at getting the p-cscf address, do you have any specific pointers on how you got yours? I haven’t found any documentatior for my own carrier (Telia in Norway), and I can’t for the life of me figure out how to extract it from Android nor pmos. Did a whack at trying to implement it in pmos, but so far, I’m hitting a wall, where I seem to be blocked from doing it through ModemManager/qmicli (where I’ve mostly been pasting llm suggestions…)

Oh, that makes perfect sense actually, I had pmos edge installed prior to your version (which I installed using your install.sh script). So now that I’m back on android, I should be able to go straight into your image and keep the modem partition hopefully 🤞

(Federation didn’t want to work from my home server with my awesome image, so I made as account here as well to repost…)

I’m just so happy you made the effort to set this up! And then I went into the same trap myself and thought I could get it working in an hour. So far I’ve managed to build the image, flash and run it and verify most features except SIM related stuff. It seems my FP6 is having trouble reading its own IMEI, both on your build and pmos edge. So I’m going back to Android just to see if I’ve borked something, then back to pmos when I get the chance.

^ That was the original message. In the meantime I’ve been back to Stock Android to verify that everything works, which I never bothered to do when I initally got the phone 😅 Everything is working though, so next evening when I get the chance, I’m diving back into pmos to see if I can get it working again. I’ve been having some trouble getting the P-CSCF address, and the internet claims that address might change when going between radio towers, so I’ve started digging into the rabbit hole of automatic retrieval through PCO via “IMS PDN”… Learning a lot of abbreviations so far, we’ll see if I get anywhere with it…
