My payment processor just terminated my account and i am reminded once again too self host literally everything.
I already have a self hosted crypto rail but for many people that is not an option, bank transfer is quite easy to do with just checking against my bank's API, but remembering from the data before i got terminated it was around 40% transfer, 40% ideal, 20% card.
Is there anyway to self host those other payment ways outside transfer?
Does anyone have experience with this?
If you do thank you very much!

Unless I completely forgot how telephony works a simless phone doesn't have an IMSI either right?
They could see the IMEI maybe? Maybe you ment that.

yeah no thanks.

I am not planning to work on the FP5 unless there is significant demand, might run a poll after i'm done with the FP6.
The most sensible phone after the FP6 seems to be the FP6 plus that will be coming out, depends on how much of the hardware is the same but since its a refresh it should be pretty similar.
Also you linked the wrong repo, my repo is: https://forgejo.catcrafts.net/Catcrafts/milos-linux

The process wasn't really designed for others yet, please give me an ~hour and i will host prebuild versions.

Got it, thank you.
I will try to add that

While celebrating my previous post of working call audio @npub1qrh…3zlr left this excellent comment:
https://ani.social/post/34656971/17805917
And this reminded me something that i and many devs sadly often forget, if its works for me it doesn't mean it works for everyone.
My philosophy is that linux should be as accesible as possible, nobody should be forced to be stuck with big tech.
So i tried my best to add orca screenreader support to plasma-mobile.
I mad this statement on my previous post
> But a successful one!
But i genuinely don't know if i can claim that today, i don't use a screenreader so i don't know what the user experience should look like. I will glady incorporate feedback.
As with my kernel patches i will be working to upstream this with KDE, since this is probably not controversial i think it should be accepted quite quickly.
# Small celebration:
I was quite happy when i saw this in my inbox:
https://lore.kernel.org/all/[email protected]/
>+maintainers:

It looks like im being upgraded from linux contributor to linux maintainer!

Some comments mentioned this and it got me thinking, would there be demand for this?
I would be selling them on my catcrafts.net website, payment methods would be my bunq so wero, bancontact, credit card and crypto.
If you are interested in this, please upvote my comment, ive been looking into this and there is quite alot of administration that comes with it, so i would like to only do this if there is actual demand.
I would be shipping to any place i can. I will be shipping from the Netherlands, so keep that in mind for import duties and shipping costs.

Don't standard linux screen readers work?
I apolotize as im not knowledgable the screen reader space on Linux but thinking about it they should work? It's both wayland after all.

So here it is! working VoLTE calls with audio on linux!
What a rollercoaster it has been i'll tell you that.
The frequency between my previous posts was only a few days, as you can see from the time since my last post this has been a *far* harder project.
But a successful one!
Now fully powered trough my new imsd project:
https://forgejo.catcrafts.net/Catcrafts/imsd
As i said in a my previous comment no matter what i did the regular modem route wasn't working, so i had to come up with my own.
This has several advantages however, call audio is now just routed trough wireplumber & pipewire, so its integrated much better.
Both inbound and outbound calls work.
# How do i get this???
The patient route is waiting until my patches get accepted upstream, a few already have and are coming in 7.3 probably (pmos runs 7.0 currently still oof), a few will probably take longer, 7.4 or beyond.
but for the ones that want to jump right on ive published everything on my forgejo:
https://forgejo.catcrafts.net/Catcrafts
I will soon be publishing a shell script that does the entire installation soon for easy installation.
Sadly there is no way to just plug in an android and do it, so there are still a few manual steps needed, but i believe the path to adoption is reducing friction as much as possible, so ill do my best to make it as easy as possible to use.
# imsd
So what is an "imsd"?
its a full userspace implementation of the IMS protocol, which drives VoLTE (4G) calls.
Normally the modem firmware drives this, but this is quite difficult to work with, now it runs fully via a standard daemon on linux!
Along with several d-bus helpers that integrate it with standard plasma-dialer.
if made a APKBUILD for pmos that is mutually exclusive with 81voltd, and loads imsd instead. so installation should be easy.
>Now will this actually work?
That's where you come in!
I am just one guy with one phone with one carrier.
I can say it works on the Fairphone 6 with KPN. it might work with other carriers and other Qualcomm phones aswell, so potentially this could work for the entire linux phone ecosystem, but i have no way to test that.
If you end up trying it, no matter if it works or doesn't work, please send me a message or open a PR, then we can make sure it works for everyone!
# donations
![](https://ani.social/pictrs/image/9673d610-cd1e-4fc0-9c04-647e6cbe12fc.webp)
I really was surprised when people asked me this, i just see myself as a guy doing this in his free time, "why would people want to send donations to me?" i thought.
I still stand by my previous point, i have a job, and this project costs me nothing except for time, i don't have any costs. So i felt kinda guilty receiving money from people.
But i would much rather spend my time making software that benefits society instead of the B2B stuff i do at my job.
I really feel greedy for saying this, but if you want to send me a thank you then that is now possible at:
https://bunq.me/catcrafts
Please don't feel any pressure to do this, doesn't matter what i get im still continuing with this bring-up. And if you don't want to donate to me there are many linux organizations that could really use the support! In my eyes we are all in the same boat with the same goal.
If you do decide to, and i cannot express my gratitude enough if you do, please write in the description that it's a donation, as this makes tax easier.
# What's next?
Ive got a bunch more stuff coming soon, while i haven't posted here in quite a while i've been plenty busy on the mailing list:
![](https://ani.social/pictrs/image/e5cf3c88-f6cd-4247-9db8-3206f742568b.webp)
So except some more posts soon.
# Bonus round
Having fully working hardware is great, but a phone that has no apps is pointless for most people, so i would like to start a discussion in the comments.
**What apps do you need that are preventing you from switching to mobile linux?**
