From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You're gonna want to do this with an app. Phone calls via cell towers are not secure.
Use Wire or Matrix or something.
I don't think there is a way to forward cellular phone calls. You'd need a phone provider which provides that feature, like a Voice-over-IP provider. Or a SIM card in your computer. Plus the right phone contract.
Kdeconnect can forward a lot of other things though, like SMS, files...
I wish there was a way to hook into calls. But as far as I know they're deliberately keeping that closed.
There must be a way to do it, cause it works flawlessly on my Mac.
I suppose along an iPhone? I mean Apple does the whole ecosystem. And this isn't really a technical limitation. Most phones have the audio stream available. Theoretically they could forward it, or record it. But on Android, the often don't seem to allow that, and Apple doesn't allow third parties (like a Linux computer) to access "their" interfaces, so I don't know if you can forward it to arbitrary computers.
I mean there are solutions. Other people here outlined that. For example mimicking a bluetooth handset. You could solder a cable to attach to a computer's AUX input. Or use a landline or different service to manage the calls whithin a PBX. But none of that is very easy to set up. Maybe the best bet is bluetooth.
Google Fi allows taking and making calls from the Messages for Web portal in the browser but ... Google
Google 🤮
In theory you should at least be able to pair your phone to your laptop and use it like a Bluetooth headset
I am doing this and it works quite well. My PC shows up as a headset on my phone and i connect to it as such. I dont have any custom software for it so its very basic and i still have to pick up the call through the phone, but once i pick up it uses the audio input/output of my desktop machine. Im on debian 12 with KDE, but i assume it should be just as easy on ubuntu.
Do you have any resources on how to do this? i'd like to give it a go as well
Previously this required some tinkering, but on my current setup it just worked out of the box. Just make sure your computers bluetooth is set to be visible to other devices, then it should pop up on your phones bluetooth search list. Make sure you give the desktop phone call and media permissions on your phone.
If this doesnt just work ootb, then you might have to change some config files to enable it, but there is lots of information out there if you look for something like "linux/distro bluetooth as sink"
Huh, thanks. That works from iOS to my Bazzite desktop flawlessly.
https://jmp.chat/ could do this depending on where you live.
Interesting, I knew they provide SIM for non eSIM phones (have a JMP SIM on the way with its USB adapter) but didn't know about that service. Can you please explain a bit more how it works?
PS: for Europeans who worry about tariffs, mine wasn't sent from the US, or Canada, but rather Netherlands, FWIW.
Haven't used this services but I keep seeing other people talking about it. From their FAQ : https://jmp.chat/faq
- Q4. How do I make a phone call with my JMP number?
The easiest way is to make a call from your Jabber app, if you are using a supporting app such as Cheogram Android, Conversations, Snikket, or Movim. Simply add a contact just as you would for messaging and then select the voice call option in your app.
- Q10. JMP currently only provides numbers in the USA and Canada. These numbers can make and receive both calls and messages with any country in the world.
Get a SIP account with a VoIP provider and run a SIP client on your laptop. I've been using Linphone on Android and it works but isn't great. It does say it has desktop versions. I haven't looked into alternatives.
Phone OS's usually won't let you get at the voice stream, to prevent malware apps from tapping your conversations.
You could alternatively use some Bluetooth hack as someone said. It would help if you were more specific about what you wanted.
This is the most solid solution IMO. I use Linphone on desktop with a Twilio phone number over SIP.
It works. Not that I get to try it often: I consider phone calls a barbaric relic of the past and get by fine without them. I use the number to receive 2FA SMS mostly.
Oof, you're gonna get your account stolen. Never do 2FA over SMS.
There is no direct way to forward calls with KDE Connect or any other app, but there might be a solution if you would mainly receive calls at home.
If you're willing to learn and configure, you could setup a PBX server with a Pi or an old machine by installing Asterisk and setting up your phone as a trunk line for it via Bluetooth (I'll find the instructions soon)
The only way I found is using MacOS (even the old versions) for doing this. The sync platform is the only one that don't cause me any delay or influence the quality of the call. Are those calls from the SIM? If it is whatsapp or other app I think you can answer directly from the client on the computer.
You're probably not talking about landlines. Some routers can act as voip servers which you can connect to with clients like Twinkle. I use that with my Fritz!box.
This is an XY solution but...
Telegram and similar services offer both calling and texting and can be carried across devices. It's linked to the same phone number, all folks would have to know is "between these hours call telegram"
Note they're not encrypted. This is not safe. Dont do it.
Not by default, but yea it is encrypted, I use almost exclusively encrypted chats through TG, even my voice and video calls are encrypted through TG.
E2e encryption is security theater though, a chance for companies to tell states "We'D lOvE tO hAnD oVeR tHaT dAtA bUt ItS eNcYpTeD".
In reality, it doesn't matter, if someone wants to snoop on your convos you can't stop them.
Google Voice is probably a good solution for you
