Can I somehow use my laptop/desktop Linux microphone and speaker or headset to call a regular phone line through my (GrapheneOS) Android 13 phone?
SIP sadly is not an option as my mobile phone provider does not hand out SIP information, it’s only possible to call with an attached SIM card.
Microsoft apparently supports something called Phone Link on Windows 11 which makes this possible. Is there a Phone Link alternative for Linux, possibly even wired via USB?
Found this discussion on the scrcpy repository and via bluetooth it only seems to work with very specific hardware, whereas injecting the audio stream from the PC microphone to the Android microphone input doesn’t seem to work.
No, sadly you can see SMS and calls and even initiate calls in some cases, but you can’t use the PC microphone and speakers/headset for talking to people.
