Cannot call at several mobile phones

[zetabeta]

hi all,

Some weeks ago it suddenly came an issue on my PinePhone with calls. When I made a call, it rang the first tune, but later it hung up, simply it stopped calling. I use Mobian OS on it.

I've been searching for any sollution , but I can't find any. I've tried installing several OS, like PostmarketOS phosh, and Manjaro Plasma Mobile, even Postmarket Plasma Mobile. And on all of them it keeps the same issue. I've noticed that when I call on some mobile phones (always the same), it only rings the first tune and hangs up, but if I call on another mobile phones, it simply runs and makes the call ok. Calling to the landline it works fine too.

It is really strange, doesn't it? Should be a problem on the PinePhone itself?

it may not be o.s. related. it may be eg25g firmware related and volte. so i recommend updating firmware either stock or partially open source firmware.

if stock firmware, i recommend 30.007.30.007 version.

i recommend these for both stock and partially open source, https://github.com/the-modem-distro/pine...ETTINGS.md .
