Use SIM card on Ubuntu or Raspian or FritzBox or any PBX for mobile telephone calls

ru flag

I'm working from home most of the time, and so I'm using a landline for telephone (flatrate to landline numbers) and internet flatrate. But sometimes I have to work onsite, so my mobile phone has a SIM with telephone flatrate and some GB Internet traffic. So most of the time my mobile phone is off and useless, as well as my mobile telephone flatrate stays unused.

I'd like to use my mobile flat to place calls from my home telephones. The simplest way would be to connect my SIM (using some USB surf stick, e.g.) to my FritzBox Fon WLAN 7390 and configure it to place calls for mobile numbers via the SIM, while placing calls to landline numbers via my landline as usual. Alas - I didn't find a way to do so. Looks like it is not made for this type of usage.

Another way could be to connect the SIM to my PC running Ubuntu. Maybe there is some software to make it available to FritzBox (or any other telephone exchange) as a SIP gateway?

Thank you for your help! TomTomTom

No, there isn't. What you want to do is technically possible but there's almost zero demand for such thing and in case it has to done with dedicated equipment that has nothing to do with computers, routers or mobile phones.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
